Why Should I Neuter My Dog?

Gus Schwabe DVM

There are three groups of people who will tell you to neuter your dog:

1) the humane societies because they have such a problem with a run-away dog population. Imagine what they go through every day having to euthanize healthy dogs (and cats) just because there are no homes for them to go to!!
2) Your local municipalities (town, county, etc.) because they don't need the complaints from residents. "your dog got into my yard and mated with my dog! I'm going to sue you!" The courts don't need to be bothered by this issue.
3) Your Veterinarian - we are concerned about the long term health of your dog.

Who should neuter their dog? Everyone who does not intend to show their dog in conformation for breeding purposes, and does not have a "stud rights" clause in their contract should have it done.

What is Neutering? Neutering is a complete castration of a male dog, not a vasectomy. The purpose is to remove the source of testosterone. The procedure is done under general anesthesia.

When should neutering be done? This has been a point of contention lately. Traditionally neutering has been done at or around six months of age because that is the age of puberty in dogs. Many groups have shown an interest in neutering earlier for a variety of reasons. Recent studies have shown that there is no harm in neonatal neutering, the only long term effect is that the growth plates of the bones close later which results in a larger or taller dog. There is essentially no difference in anesthetic risk. I would recommend neutering anytime after a puppy has had at least two of it's puppy vaccinations for immune reasons. An adult dog can be neutered anytime and this is recommended for retired show dogs who are no longer at stud. It may also be a required part of the treatment for adult and geriatric dogs. The anesthetic risk is, of course, lower in young dogs.

Why should a dog be neutered? Here are the MEDICAL reasons, there are also many other good and valid reasons to neuter. Testosterone is a very powerful anabolic steroid with many short and long term effects. Here is a list of some of the medical conditions proven to be influenced by Testosterone.

1) Prostate effects -

  *Benign Prostatic hypertrophy - a gross enlargement of the prostate gland, as occurs in human men. In the dog this enlargement does not cause difficulty in urination but may create serious constipation.

  *Primary Prostatic Carcinoma - a highly metastatic form of cancer which is usually fatal.
  *Generalized Noninfectious Prostatitis - an acute inflammation of the prostate which causes pain on urination and is usually accompanied by hematuria, blood in the urine.

  *Prostatic Abscess - either single or multiple microabscesses, this is an infection of the gland caused by bacteria. The gland is more susceptible to infection when under the influence of testosterone.

2) Hernias - There are a number of hernias caused by Testosterone, they include: Scrotal hernias, inguinal hernias (in the groin), and perineal hernias (the area next to the tail). These hernias all require surgical correction. These hernias can be severe and life threatening especially if an organ becomes entrapped in the hernia.

3) Cancer - numerous cancers have been directly associated with testosterone, they include: Sertolli Cell tumors, Leydig Cell tumors, Perianal adenocarcinoma, Seminomas and interstitial cell tumors. Also Primary Prostatic Carcinoma, as above, All require surgery and some may also require Radiation and/or Chemotherapy as well.

4) Infections - Brucellosis is the worst, it has only slight chronic signs in the dog but causes abortion in the bitch. Balanoposthitis a chronic infection of the prepuce and penis, inside the sheath, this is the dog that is dripping droplets of pus from the opening of the prepuce (or sheath).

5) Miscellaneous - Paraphimosis - the inability to resolve an erection, the penis is stuck in an erectile condition and is very painful. Perianal and Rectal fistulas - infected tracts from the rectum to an opening near the anus which is usually draining blood, pus and faeces. This is a particularly nasty condition and usually requires a board certified surgeon. The treatment may require removal of the anus and or rectum and the dog may experience faecal incontinence afterwards.
There may be other conditions as well, I've written this "off the top of my head".

All of the above conditions can be prevented by neutering your dog. Every man who owns a dog should read this and consider if he wants to put his dog through this. It is a proven fact that neutered dogs live longer, healthier, and happier lives. We should not anthropromorphize our dogs. That is to put human emotions on them, a dog doesn't care if there is anything in his scrotum!! For those who feel there is a cosmetic need for it there are prosthetic implants, called Neuticles tm, which can be placed in the scrotum at the time of neutering. I hope that this helps people to come to the right decision and resolves some family arguments.

Why Should I Spay My Bitch

Gus Schwabe DVM

There are three groups of people who will tell you to spay your bitch:

1) the humane societies - because they have such a problem with a run-away dog population. Imagine what they go through every day having to euthanize healthy dogs just because there are no homes for them to go to!!

2) Your local municipalities (towns, counties, etc.) because they don’t need the complaints from residents. “Your dog got into my yard and mated with my dog. I’m going to sue you!” The courts don’t need to be bothered by this issue.

3) Your Veterinarian - we are concerned about the long-term health of your dog.

Who should have their dog spayed? Everyone who does not intend to show their dog in conformation for breeding purposes, and does not have a “breeding clause” in their contract should have it done.

What is a spay operation? - A spay is a complete Ovariohysterectomy. The standard surgical sterilization of a female dog. In the United States, at least, the Ovaries and the entire Uterus are removed. In speaking with colleagues in other parts of the world this may not be the case universally. I have heard that in some countries only the ovaries are removed and the uterus is left intact. In my mind there is no advantage to this. The purpose is to remove the source of Estrogen and prevent uterine complications such as infections as well as sterilization. The procedure is an abdominal surgery and is done under general anesthesia.

When should the spay be done? - This has been a source of contention lately. Traditionally, a spay is done at or about six months of age because this is the age of puberty in dogs. Some have recommended allowing the bitch to have her first heat cycle, as you will see this is not advised. Many groups have shown an interest in spaying earlier for a variety of reasons. Recent studies have shown that there is no harm in neonatal spaying, the only long-term effect is that the growth plates of the bones close later which results in a larger and/or taller bitch. There is essentially no difference in anesthetic risk. I would recommend spaying anytime after a puppy has had at least two of its puppy vaccinations for immune reasons. An adult dog can be spayed anytime and this is recommended for retired show dogs or breeding bitches that have had a history of reproductive problems. Such problems include, but are not limited to, a history of pregnancy failures such as early embryonic death and reabsorbtion, repeated failure to conceive, abortion or difficulty whelping in breeds not usually requiring cesarean sections. It may also be a required part of the treatment for conditions occurring in adult or geriatric dogs. The anesthetic risk is, of course, lower in young healthy bitches.

Why should a bitch be spayed? - Here are the MEDICAL reasons, there are also many other good and valid reasons to have your bitch spayed. Estrogen is a very powerful anabolic steroid with many short and long term effects. Here is a list of some of the medical conditions proven to be influenced by Estrogen.

1) Ovarian - Primary Ovarian Cancer - just as lethal id dogs as it is in Women, Cystic conditions of the Ovaries - follicular cysts cause a prolonged “heat cycle”, leuteal cysts cause profound hormonal changes in the uterus.

2) Uterine - Many of the conditions occurring in women also occur in the bitch including fibroid growths, endometritis, endometriosis, hydrometra, mucometra, and pyometra, leiomyoma, leiomyosarcoma of the uterine wall and cervical cancer. Uterine torsion, as dangerous as gastric torsion, uterine prolapse and uterine rupture.

3) Vaginal Hyperplasia.

4) The presence of Estrogen in the body has a profound effect on the effectiveness of the treatments for Diabetes and Epilepsy. Diabetes is much more common in intact bitches than in spayed bitches. Management of these diseases is much simpler in the spayed bitch.

5) Mammary Glands - The occurrence of Mammary Cysts and Tumors is directly related to the age of spaying. Spaying before the first estrus cycle decreases the incidence of mammary tumors to less than 0.5% compared to intact bitches, if done after one estrus cycle the risk of mammary tumors rises to 8.0%, after two cycles the risk increases to 26%. Spaying a bitch after 2 1/2 years of age has no preventative effect on mammary gland tumors.* There is anecdotal evidence, however, that spaying as an adult reduces the risk of metastatic and malignant tumors of the mammary glands.
*Fanton, J.W. and Withrow, S.J., Calif. Vet. 35:12, 1981

All of the above conditions can be prevented by spaying your bitch at an early age. Anyone who owns a dog should read this and consider if they want to take the risk of having their pet go through this. It is a proven fact that spayed bitches live a longer, happier, and healthier life. I hope this helps people come to the right decision, keeping the dog’s welfare in mind.

I want to say a few words about “spay/neuter health
benefits” for dogs.  I do this to rebut a
number of rumors, exaggerations and overt lies. 
 It is sad, I believe, that many
people make important decisions based only on rumors and do not do good research
before spaying or neutering their dogs.

I am originally from Europe -Ukraine.  People spay and neuter dogs there in only rare
cases, and lots of dogs live long and happy lives. I was shocked, when I found
out, that the most American dogs are going through these kinds of procedures
without real necessity most of the time.  I want to tell about my personal canine behavioral
observations, and research on the spay/neuter subject.

Behavior.

I do agree, that dogs of “fighter” breed (Rottweiler, Pit
bull terriers, Staffordshire terriers, etc.)  should be neutered, because it doesn’t matter
how well trained they are, they can lose their minds sometimes.  It’s simply in their nature.  However, I don’t agree that the toy breed
males should be neutered, unless they are not monitored.  

People tell stories about “nasty male habits of marking in
the house”, which was another “discovery” for me.  What the heck are people talking about?  We’re talking about DOGS, but not CATS!  Here are a couple of observations that prove the
insanity of this point.  I’ve had two
male Poms.  Neither of them were used for
breeding.  They NEVER marked in the
house, because they were simply well-trained and were doing potty only outside,
like any other well-behaved dog.  It is a
matter of good training!!!  Another thing
is; when we recently bred our female Pom to a nice small KENNEL male Pom (which
was not potty trained --and he was trying to mark things inside the house) Omg!
Oh miracle! I trained him to quit doing that “nasty male habit” in just 5
days!!!!!!!!  I’m talking about an intact
male dog that was NEVER potty trained!

                    My research on health benefits of the spay/neuter
subject.

First of all, spaying/neutering has both positive AND
adverse health effects on the dogs.

I found one good scientific research report on this subject.
 It appears, that spaying has more
advantages , than disadvantages, because it 
eliminates small risks of mammary tumors and pyometra.  Neutering, on the on other hand, has more
disadvantages, than advantages like “quadruples the small risk (<0.6%)
of prostate cancer”.  All of those risks
have a very small rate of health problems, and you can read about them in
“summary” down below.

Another thing is, if spaying/neutering is done before
1 year of age, it increases the risk of osteosarcoma (bone cancer) in both
sexes.  This is a common problem that can
appear in medium and larger breeds.  Many
“experienced” breeders suggest fixing the dog before 1 year of age, which is
risky kind of thing… Breeders don’t know everything. Heck, nobody knows
everything; but if you are ready to make an important and life changing
decision for your dog –you had better do full research on this subject.

This is the summary of the
research, that was done at Rutgers University (see link below)
after numerous dogs had been tested, and large amount of data compiled --which
makes it an excellent reference on this subject.

“SUMMARY

An objective reading of the
veterinary medical literature reveals a complex situation with respect to the
longterm

health risks and benefits
associated with spay/neuter in dogs. The evidence shows that spay/neuter

Page 2 of 12

correlates with both positive AND
adverse health effects in dogs. It also suggests how much we really do

not yet understand about this
subject.

On balance, it appears that no
compelling case can be made for neutering most male dogs, especially

immature male dogs, in order to
prevent future health problems. The number of health problems associated

with neutering may exceed the
associated health benefits in most cases.

On the positive side, neutering
male dogs

 eliminates the
small risk (probably <1%) of dying from testicular cancer

 reduces the risk
of non-cancerous prostate disorders

 reduces the risk
of perianal fistulas

 may possibly
reduce the risk of diabetes (data inconclusive)

On the negative side, neutering
male dogs

 if done before 1
year of age, significantly increases the risk of osteosarcoma (bone cancer);
this is a

common cancer in medium/large and
larger breeds with a poor prognosis.

 increases the
risk of cardiac hemangiosarcoma by a factor of 1.6

 triples the risk
of hypothyroidism

 increases the
risk of progressive geriatric cognitive impairment

 triples the risk
of obesity, a common health problem in dogs with many associated health
problems

 quadruples the
small risk (<0.6%) of prostate cancer

 doubles the small
risk (<1%) of urinary tract cancers

 increases the
risk of orthopedic disorders

 increases the
risk of adverse reactions to vaccinations

For female dogs, the situation is
more complex. The number of health benefits associated with spaying may

exceed the associated health
problems in some (not all) cases. On balance, whether spaying improves the

odds of overall good health or
degrades them probably depends on the age of the female dog and the

relative risk of various diseases
in the different breeds.

On the positive side, spaying
female dogs

 if done before
2.5 years of age, greatly reduces the risk of mammary tumors, the most common

malignant tumors in female dogs

 nearly eliminates
the risk of pyometra, which otherwise would affect about 23% of intact female

dogs; pyometra kills about 1% of
intact female dogs

 reduces the risk
of perianal fistulas

 removes the very
small risk (_0.5%) from uterine, cervical, and ovarian
tumors

On the negative side, spaying
female dogs

 if done before 1
year of age, significantly increases the risk of osteosarcoma (bone cancer);
this is a

common cancer in larger breeds
with a poor prognosis

 increases the
risk of splenic hemangiosarcoma by a factor of 2.2 and cardiac hemangiosarcoma
by

a factor of >5; this is a
common cancer and major cause of death in some breeds

 triples the risk
of hypothyroidism

 increases the
risk of obesity by a factor of 1.6-2, a common health problem in dogs with many

associated health problems

 causes urinary
“spay incontinence” in 4-20% of female dogs

 increases the
risk of persistent or recurring urinary tract infections by a factor of 3-4

 increases the
risk of recessed vulva, vaginal dermatitis, and vaginitis, especially for
female dogs

spayed before puberty

 doubles the small
risk (<1%) of urinary tract tumors

 increases the
risk of orthopedic disorders

 increases the
risk of adverse reactions to vaccinations

One thing is clear – much of the
spay/neuter information that is available to the public is unbalanced and

contains claims that are
exaggerated or unsupported by evidence. Rather than helping to educate pet

Page 3 of 12

owners, much of it has contributed
to common misunderstandings about the health risks and benefits

associated of spay/neuter in dogs.

The traditional spay/neuter age of
six months as well as the modern practice of pediatric spay/neuter appear

to predispose dogs to health risks
that could otherwise be avoided by waiting until the dog is physically

mature, or perhaps in the case of
many male dogs, foregoing it altogether unless medically necessary.

The balance of long-term health
risks and benefits of spay/neuter will vary from one dog to the next. Breed,

age, and gender are variables that
must be taken into consideration in conjunction with non-medical factors

for each individual dog.
Across-the-board recommendations for all pet dogs do not appear to be

supportable from findings in the veterinary medical
literature.”

                My research on
health benefits of the spay/neuter subject.

     First of all, spaying/neutering has both positive AND
adverse health effects on the dogs.

   I found one good scientific research report on this subject.
 It appears, that spaying has more
advantages , than disadvantages, because it 
eliminates small risks of mammary tumors and pyometra.  
Neutering, on the on other hand, has more
disadvantages, than advantages like “quadruples the small risk (<0.6%)
of prostate cancer”.  All of those risks
have a very small rate of health problems, and you can read about them in
“summary” down below.

   Another thing is, if spaying/neutering is done before
1 year of age, it increases the risk of osteosarcoma (bone cancer) in both
sexes.  This is a common problem that can
appear in medium and larger breeds.  Many
“experienced” breeders suggest fixing the dog before 1 year of age, which is
risky kind of thing… Breeders don’t know everything. Heck, nobody knows
everything; but if you are ready to make an important and life changing
decision for your dog –you had better do full research on this subject.<link rel="File-List" href="file:///C:%5CUsers%5Cowner%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_filelist.xml"><!--[if gte mso 9]>

after numerous dogs had been tested, and large amount of data compiled --which
makes it an excellent reference on this subject.

Gus Schwabe DVM There are three groups of people who will tell you to neuter your dog: 1) the humane societies because they have such a problem with a run-away dog population. Imagine what they go through every day having to euthanize healthy dogs (and cats) just because there are no homes for them to go to!! 2) Your local municipalities (town, county, etc.) because they don't need the complaints from residents. "your dog got into my yard and mated with my dog! I'm going to sue you!" The courts don't need to be bothered by this issue. 3) Your Veterinarian - we are concerned about the long term health of your dog. Who should neuter their dog? Everyone who does not intend to show their dog in conformation for breeding purposes, and does not have a "stud rights" clause in their contract should have it done. What is Neutering? Neutering is a complete castration of a male dog, not a vasectomy. The purpose is to remove the source of testosterone. The procedure is done under general anesthesia. When should neutering be done? This has been a point of contention lately. Traditionally neutering has been done at or around six months of age because that is the age of puberty in dogs. Many groups have shown an interest in neutering earlier for a variety of reasons. Recent studies have shown that there is no harm in neonatal neutering, the only long term effect is that the growth plates of the bones close later which results in a larger or taller dog. There is essentially no difference in anesthetic risk. I would recommend neutering anytime after a puppy has had at least two of it's puppy vaccinations for immune reasons. An adult dog can be neutered anytime and this is recommended for retired show dogs who are no longer at stud. It may also be a required part of the treatment for adult and geriatric dogs. The anesthetic risk is, of course, lower in young dogs. Why should a dog be neutered? Here are the MEDICAL reasons, there are also many other good and valid reasons to neuter. Testosterone is a very powerful anabolic steroid with many short and long term effects. Here is a list of some of the medical conditions proven to be influenced by Testosterone. 1) Prostate effects - Benign Prostatic hypertrophy - a gross enlargement of the prostate gland, as occurs in human men. In the dog this enlargement does not cause difficulty in urination but may create serious constipation. Primary Prostatic Carcinoma - a highly metastatic form of cancer which is usually fatal. Generalized Noninfectious Prostatitis - an acute inflammation of the prostate which causes pain on urination and is usually accompanied by hematuria, blood in the urine. Prostatic Abscess - either single or multiple microabscesses, this is an infection of the gland caused by bacteria. The gland is more susceptible to infection when under the influence of testosterone. 2) Hernias - There are a number of hernias caused by Testosterone, they include: Scrotal hernias, inguinal hernias (in the groin), and perineal hernias (the area next to the tail). These hernias all require surgical correction. These hernias can be severe and life threatening especially if an organ becomes entrapped in the hernia. 3) Cancer - numerous cancers have been directly associated with testosterone, they include: Sertolli Cell tumors, Leydig Cell tumors, Perianal adenocarcinoma, Seminomas and interstitial cell tumors. Also Primary Prostatic Carcinoma, as above, All require surgery and some may also require Radiation and/or Chemotherapy as well. 4) Infections - Brucellosis is the worst, it has only slight chronic signs in the dog but causes abortion in the bitch. Balanoposthitis a chronic infection of the prepuce and penis, inside the sheath, this is the dog that is dripping droplets of pus from the opening of the prepuce (or sheath). 5) Miscellaneous - Paraphimosis - the inability to resolve an erection, the penis is stuck in an erectile condition and is very painful. Perianal and Rectal fistulas - infected tracts from the rectum to an opening near the anus which is usually draining blood, pus and faeces. This is a particularly nasty condition and usually requires a board certified surgeon. The treatment may require removal of the anus and or rectum and the dog may experience faecal incontinence afterwards. There may be other conditions as well, I've written this "off the top of my head". All of the above conditions can be prevented by neutering your dog. Every man who owns a dog should read this and consider if he wants to put his dog through this. It is a proven fact that neutered dogs live longer, healthier, and happier lives. We should not anthropromorphize our dogs. That is to put human emotions on them, a dog doesn't care if there is anything in his scrotum!! For those who feel there is a cosmetic need for it there are prosthetic implants, called Neuticles tm, which can be placed in the scrotum at the time of neutering. I hope that this helps people to come to the right decision and resolves some family arguments. Why Should I Spay My Bitch Gus Schwabe DVM There are three groups of people who will tell you to spay your bitch: 1) the humane societies - because they have such a problem with a run-away dog population. Imagine what they go through every day having to euthanize healthy dogs just because there are no homes for them to go to!! 2) Your local municipalities (towns, counties, etc.) because they don’t need the complaints from residents. “Your dog got into my yard and mated with my dog. I’m going to sue you!” The courts don’t need to be bothered by this issue. 3) Your Veterinarian - we are concerned about the long-term health of your dog. Who should have their dog spayed? Everyone who does not intend to show their dog in conformation for breeding purposes, and does not have a “breeding clause” in their contract should have it done. What is a spay operation? - A spay is a complete Ovariohysterectomy. The standard surgical sterilization of a female dog. In the United States, at least, the Ovaries and the entire Uterus are removed. In speaking with colleagues in other parts of the world this may not be the case universally. I have heard that in some countries only the ovaries are removed and the uterus is left intact. In my mind there is no advantage to this. The purpose is to remove the source of Estrogen and prevent uterine complications such as infections as well as sterilization. The procedure is an abdominal surgery and is done under general anesthesia. When should the spay be done? - This has been a source of contention lately. Traditionally, a spay is done at or about six months of age because this is the age of puberty in dogs. Some have recommended allowing the bitch to have her first heat cycle, as you will see this is not advised. Many groups have shown an interest in spaying earlier for a variety of reasons. Recent studies have shown that there is no harm in neonatal spaying, the only long-term effect is that the growth plates of the bones close later which results in a larger and/or taller bitch. There is essentially no difference in anesthetic risk. I would recommend spaying anytime after a puppy has had at least two of its puppy vaccinations for immune reasons. An adult dog can be spayed anytime and this is recommended for retired show dogs or breeding bitches that have had a history of reproductive problems. Such problems include, but are not limited to, a history of pregnancy failures such as early embryonic death and reabsorbtion, repeated failure to conceive, abortion or difficulty whelping in breeds not usually requiring cesarean sections. It may also be a required part of the treatment for conditions occurring in adult or geriatric dogs. The anesthetic risk is, of course, lower in young healthy bitches. Why should a bitch be spayed? - Here are the MEDICAL reasons, there are also many other good and valid reasons to have your bitch spayed. Estrogen is a very powerful anabolic steroid with many short and long term effects. Here is a list of some of the medical conditions proven to be influenced by Estrogen. 1) Ovarian - Primary Ovarian Cancer - just as lethal id dogs as it is in Women, Cystic conditions of the Ovaries - follicular cysts cause a prolonged “heat cycle”, leuteal cysts cause profound hormonal changes in the uterus. 2) Uterine - Many of the conditions occurring in women also occur in the bitch including fibroid growths, endometritis, endometriosis, hydrometra, mucometra, and pyometra, leiomyoma, leiomyosarcoma of the uterine wall and cervical cancer. Uterine torsion, as dangerous as gastric torsion, uterine prolapse and uterine rupture. 3) Vaginal Hyperplasia. 4) The presence of Estrogen in the body has a profound effect on the effectiveness of the treatments for Diabetes and Epilepsy. Diabetes is much more common in intact bitches than in spayed bitches. Management of these diseases is much simpler in the spayed bitch. 5) Mammary Glands - The occurrence of Mammary Cysts and Tumors is directly related to the age of spaying. Spaying before the first estrus cycle decreases the incidence of mammary tumors to less than 0.5% compared to intact bitches, if done after one estrus cycle the risk of mammary tumors rises to 8.0%, after two cycles the risk increases to 26%. Spaying a bitch after 2 1/2 years of age has no preventative effect on mammary gland tumors.* There is anecdotal evidence, however, that spaying as an adult reduces the risk of metastatic and malignant tumors of the mammary glands. *Fanton, J.W. and Withrow, S.J., Calif. Vet. 35:12, 1981 All of the above conditions can be prevented by spaying your bitch at an early age. Anyone who owns a dog should read this and consider if they want to take the risk of having their pet go through this. It is a proven fact that spayed bitches live a longer, happier, and healthier life. I hope this helps people come to the right decision, keeping the dog’s welfare in mind.

I do this to rebut a number of rumors, exaggerations and overt lies. It is sad, I believe, that many people make important decisions based only on rumors and do not do good research before spaying or neutering their dogs. I am originally from Europe -Ukraine. People spay and neuter dogs there in only rare cases, and lots of dogs live long and happy lives. I was shocked, when I found out, that the most American dogs are going through these kinds of procedures without real necessity most of the time. I want to tell about my personal canine behavioral observations, and research on the spay/neuter subject. Behavior. I do agree, that dogs of “fighter” breed (Rottweiler, Pit bull terriers, Staffordshire terriers, etc.) should be neutered, because it doesn’t matter how well trained they are, they can lose their minds sometimes. It’s simply in their nature. However, I don’t agree that the toy breed males should be neutered, unless they are not monitored. People tell stories about “nasty male habits of marking in the house”, which was another “discovery” for me. What the heck are people talking about? We’re talking about DOGS, but not CATS! Here are a couple of observations that prove the insanity of this point. I’ve had two male Poms. Neither of them were used for breeding. They NEVER marked in the house, because they were simply well-trained and were doing potty only outside, like any other well-behaved dog. It is a matter of good training!!! Another thing is; when we recently bred our female Pom to a nice small KENNEL male Pom (which was not potty trained --and he was trying to mark things inside the house) Omg! Oh miracle! I trained him to quit doing that “nasty male habit” in just 5 days!!!!!!!! I’m talking about an intact male dog that was NEVER potty trained! My research on health benefits of the spay/neuter subject. First of all, spaying/neutering has both positive AND adverse health effects on the dogs. I found one good scientific research report on this subject. It appears, that spaying has more advantages , than disadvantages, because it eliminates small risks of mammary tumors and pyometra. Neutering, on the on other hand, has more disadvantages, than advantages like “quadruples the small risk (<0.6%) of prostate cancer”. All of those risks have a very small rate of health problems, and you can read about them in “summary” down below. Another thing is, if spaying/neutering is done before 1 year of age, it increases the risk of osteosarcoma (bone cancer) in both sexes. This is a common problem that can appear in medium and larger breeds. Many “experienced” breeders suggest fixing the dog before 1 year of age, which is risky kind of thing… Breeders don’t know everything. Heck, nobody knows everything; but if you are ready to make an important and life changing decision for your dog –you had better do full research on this subject. This is the summary of the research, that was done at Rutgers University (see link below) after numerous dogs had been tested, and large amount of data compiled --which makes it an excellent reference on this subject. “SUMMARY An objective reading of the veterinary medical literature reveals a complex situation with respect to the longterm health risks and benefits associated with spay/neuter in dogs. The evidence shows that spay/neuter Page 2 of 12 correlates with both positive AND adverse health effects in dogs. It also suggests how much we really do not yet understand about this subject. On balance, it appears that no compelling case can be made for neutering most male dogs, especially immature male dogs, in order to prevent future health problems. The number of health problems associated with neutering may exceed the associated health benefits in most cases. On the positive side, neutering male dogs eliminates the small risk (probably <1%) of dying from testicular cancer reduces the risk of non-cancerous prostate disorders reduces the risk of perianal fistulas may possibly reduce the risk of diabetes (data inconclusive) On the negative side, neutering male dogs if done before 1 year of age, significantly increases the risk of osteosarcoma (bone cancer); this is a common cancer in medium/large and larger breeds with a poor prognosis. increases the risk of cardiac hemangiosarcoma by a factor of 1.6 triples the risk of hypothyroidism increases the risk of progressive geriatric cognitive impairment triples the risk of obesity, a common health problem in dogs with many associated health problems quadruples the small risk (<0.6%) of prostate cancer doubles the small risk (<1%) of urinary tract cancers increases the risk of orthopedic disorders increases the risk of adverse reactions to vaccinations For female dogs, the situation is more complex. The number of health benefits associated with spaying may exceed the associated health problems in some (not all) cases. On balance, whether spaying improves the odds of overall good health or degrades them probably depends on the age of the female dog and the relative risk of various diseases in the different breeds. On the positive side, spaying female dogs if done before 2.5 years of age, greatly reduces the risk of mammary tumors, the most common malignant tumors in female dogs nearly eliminates the risk of pyometra, which otherwise would affect about 23% of intact female dogs; pyometra kills about 1% of intact female dogs reduces the risk of perianal fistulas removes the very small risk (_0.5%) from uterine, cervical, and ovarian tumors On the negative side, spaying female dogs if done before 1 year of age, significantly increases the risk of osteosarcoma (bone cancer); this is a common cancer in larger breeds with a poor prognosis increases the risk of splenic hemangiosarcoma by a factor of 2.2 and cardiac hemangiosarcoma by a factor of >5; this is a common cancer and major cause of death in some breeds triples the risk of hypothyroidism increases the risk of obesity by a factor of 1.6-2, a common health problem in dogs with many associated health problems causes urinary “spay incontinence” in 4-20% of female dogs increases the risk of persistent or recurring urinary tract infections by a factor of 3-4 increases the risk of recessed vulva, vaginal dermatitis, and vaginitis, especially for female dogs spayed before puberty doubles the small risk (<1%) of urinary tract tumors increases the risk of orthopedic disorders increases the risk of adverse reactions to vaccinations One thing is clear – much of the spay/neuter information that is available to the public is unbalanced and contains claims that are exaggerated or unsupported by evidence. Rather than helping to educate pet Page 3 of 12 owners, much of it has contributed to common misunderstandings about the health risks and benefits associated of spay/neuter in dogs. The traditional spay/neuter age of six months as well as the modern practice of pediatric spay/neuter appear to predispose dogs to health risks that could otherwise be avoided by waiting until the dog is physically mature, or perhaps in the case of many male dogs, foregoing it altogether unless medically necessary. The balance of long-term health risks and benefits of spay/neuter will vary from one dog to the next. Breed, age, and gender are variables that must be taken into consideration in conjunction with non-medical factors for each individual dog. Across-the-board recommendations for all pet dogs do not appear to be supportable from findings in the veterinary medical literature.” The link to the full version: http://www.naiaonline.org/pdfs/LongTermHealthEffectsOfSpayNeuterInDogs.pdf The same study has been used to oppose the Californian legislation on mandatory spay/neuter by AVMA ( American Veterinary Medical Association) http://saveourdogs.net/category/health/

Date Posted：06/29/2010 6:43 AMCopy HTML First of all, spaying/neutering has both positive AND adverse health effects on the dog. I found one good scientific research report on this subgect.(Rutgers University) It appears, that spaying has more advantages, than disadvantages, because it eliminates small risks of mammary tumors and pyometra. Neutering, on the other hand, has more disadvantages, than advantages like "quadruples the small risk (<0.6%) of prostate cancer." All of those risks have a very small rate of health problems and you can read about them here<link rel="File-List" href="file:///C:%5CUsers%5Cowner%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_filelist.xml"><!--[if gte mso 9]> <link rel="colorSchemeMapping" href="file:///C:%5CUsers%5Cowner%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_colorschememapping.xml"><!--[if gte mso 9]> Normal 0 false false false EN-US X-NONE X-NONE <!-- /* Font Definitions / @font-face {font-family:Helvetica; panose-1:2 11 6 4 2 2 2 2 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-536859905 -1073711037 9 0 511 0;} @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-1610611985 1107304683 0 0 415 0;} @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-520092929 1073786111 9 0 415 0;} / Style Definitions / p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin-top:0in; margin-right:0in; margin-bottom:10.0pt; margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} a:link, span.MsoHyperlink {mso-style-priority:99; color:blue; mso-themecolor:hyperlink; text-decoration:underline; text-underline:single;} a:visited, span.MsoHyperlinkFollowed {mso-style-noshow:yes; mso-style-priority:99; color:purple; mso-themecolor:followedhyperlink; text-decoration:underline; text-underline:single;} .MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} .MsoPapDefault {mso-style-type:export-only; margin-bottom:10.0pt; line-height:115%;} @page WordSection1 {size:8.5in 11.0in; margin:1.0in 1.0in 1.0in 1.0in; mso-header-margin:.5in; mso-footer-margin:.5in; mso-paper-source:0;} div.WordSection1 {page:WordSection1;} --> <!--[if gte mso 10]> / Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} : http://www.naiaonline.org/pdfs/LongTermHealthEffectsOfSpayNeuterInDogs.pdf Another thing is, if spaying/neutering is done before 1 year of age, it increases the risk of osteosarcoma(bone cancer) in both sexes. This is the common problem that can appear in medium and larger breeds. Many "experienced" breeders suggest fixing the dog before 1 year of age, which is risky kind of thing... Breeders don't know everything. Heck, nobody knows everything; but if you are ready to make an important and life changing decision for your dog - you had better do full research on this subject.
