We went to visit my daughter last Sunday ,she has a Chihauhau around six months old and her daughter has a Dachshund around the same age,and they were told when they took the dogs for their vaccinations,that it is law now here in south australia for the dogs to be desexed by the time they are six months old and apparently pups in the animal welfare shelters have to be desexed before they are adopted no matter what age.
It is because of the back yard and puppy mill breeders, that the councils have brought in the new laws which is fair enough,but just imagine the problems the poor little dogs will have when they get older.
Do they have similar laws in your part of the world?

there is no law here on spay and neuter, shelters do it before the dog or cat can be adopted but owners can do it or not its up to them. I understand why the spay and neuter before adoption because of irresponsible owners and the over population problem but they aren't taking into account the effect it can have on the dog. Spay and neuter done before the animal is fully matured can have life long problems. Those hormones are there for a reason, let them do their job and let the dog grow properly. Unless there is a medical reason I do not neuter my males, an intact male is healthier than a neutered one. and my females I do after the second heat cycle. The legs and nose grow longer in both sexes if done early and this leads to stretching the ligaments in the knees which contributes to crucia tears requiring surgery. And done before they are mentally mature stops them from maturing and you have a dog that always acts like a puppy. Among other things that is the reason I wait to spay. And neither sex should be done before the growth plates have closed

First of all there is no such thing as desexing. Taking out the gonads does not change X and Y chromosomes in every cell. They are still males and females.

I beg to differ with Linda. There is no consequence to spaying female dogs before their first heat. I have read early neutering increases the risk the lower urethra will be blocked, which is treated by reconstructive surgery, but this claim has been debunked; it is no worse at 3 months than it is at 6 months. I think that is just an excuse some people who don't want to get their puppies and kittens neutered made up.

I don't know where you get your information but obviously what you read is biased towards early spay and neuter So read this article and there are many more like it

. Spay/Neuter and Joint Disease
We’ll get to the Vizsla study that I mentioned later. They didn’t investigate the link between spay/neuter and joint disease, but they didn’t really need to – there was already plenty of research showing the link.

Hip Dysplasia
A study on Golden Retrievers found that male dogs who were neutered before 12 months of age had double the risk of hip dysplasia than their intact counterparts (Torres de la Riva G, Hart BL, Farver TB, Oberbauer AM, Messam LLM, et al. (2013) Neutering Dogs: Effects on Joint Disorders and Cancers in Golden Retrievers)

Other research shows that dogs sterilized before the age of six months have a 70% increased risk of developing hip dysplasia. The authors of this study (Spain et al, JAVMA 2004), propose that …

it is possible that the increase in bone length that results from early-age gonadectomy results in changes in joint conformation, which could lead to a diagnosis of hip dysplasia.

There’s even more evidence that spay/neuter can increase the risk of hip dysplasia.

Van Hagen et al (Am J Vet Res, Feb 2005), found that of the sample dogs diagnosed with hip dysplasia, those that were neutered six months prior to the diagnosis were nearly twice as likely to develop hip dysplasia.

Interestingly, a study by Dannuccia et al (Calcif Tissue Int, 1986), found that removing the ovaries of Beagles caused increased remodeling of the pelvic bone, which also suggests an increased risk of hip dysplasia with spay.

Cruciate Ligament Tears
Cranial cruciate ligament tears have also been linked to spay/neuter in numerous studies.

The Golden Retriever study found that although there were no cases of cruciate tear in the intact dogs, 5% of males neutered before 12 months and 8% of females did suffer tears.

Whitehair et al (JAVMA Oct 1993), found that spayed and neutered dogs of any age were twice as likely to suffer cranial cruciate ligament rupture. Slauterbeck et al also found an increased risk (Clin Orthop Relat Res Dec 2004).

Chris Zinc DVM PhD DACVP explains,

…if the femur has achieved its genetically determined normal length at eight months when a dog gets spayed or neutered, but the tibia, which normally stops growing at 12 to 14 months of age continues to grow, then an abnormal angle may develop at the stifle. In addition, with the extra growth, the lower leg below the stifle likely becomes heavier (because it is longer), and may cause increased stresses on the cranial cruciate ligament.

Additionally, sterilization can cause a loss of bone mass (Martin et al, Bone 1987), and obesity (Edney et al, Vet Rec Apr 1986).

Both of these factors could lead to an increased risk of cranial cruciate ligament tear and hip dysplasia. Furthermore, spayed/neutered dogs are greater than three times more likely to suffer from patellar luxation (Vidoni et al, Wien Tierartztl Mschr 2005).

But there are even more sinister issues with spay/neuter.

2. Spay/Neuter and Cancer
Contrary to popular belief, we can’t spay/neuter cancer and, in fact, this surgery largely increases the risk of many common canine cancers.

MALES vs FEMALES: The Golden Retriever study looked at cancer rates and found that the incidence of lymphosarcoma was three times higher in males neutered before 12 months of age. Interestingly the percentage of hemangiosarcoma in females spayed after 12 months was four times higher than that of intact and even early-spayed females. Additionally, 6% of females spayed after 12 months were affected with mast cell cancer, while there were zero cases among the intact females.

These results are similar to other studies.

The more recent Vizsla study found that spayed females had significantly higher rates of hemangiosarcoma (nine times higher) than intact females.

They also found that spayed/neutered dogs were 3.5% more likely to suffer mast cell cancer and 4.3 times more likely to suffer lymphoma. (M. Christine Zink, DVM, PhD et al., Evaluation of the risk and age of onset of cancer and behavioral disorders in gonadectomized Vizslas. JAVMA, Vol 244, No. 3, February 1, 2014)

SPAYED vs INTACT: In fact, the incidence of all cancers in spayed females was 6.5 times higher and in neutered males was 3.6 times higher than intact dogs.

YOUNG DOGS: They also found that the younger the dogs were spayed/neutered, the younger they were when diagnosed with cancer.

Waters et al. (Exploring mechanisms of sex differences in longevity: lifetime ovary exposure and exceptional longevity in dogs) found similar results in their study of female Rottweilers. The researchers set out to determine whether retaining the ovaries contributed to longevity. In Rottweilers, the major causes of death are sarcoma and other cancers, which account for 38% and 73% of deaths respectively.

After excluding all cancer deaths, females who kept their ovaries during the first seven years of life were more than nine times more likely to reach exceptional longevity than females with the shortest ovary exposure. Although intact female dogs were more likely than males to achieve exceptional longevity, that advantage was erased with spay.

3. Spay/Neuter and Behavior
Although spay/neuter had been previously linked to cognitive impairment and even a three fold risk of hypothyroidism, which often creates behavior changes, the Viszla study yielded some particularly interesting insight into this link.

In the study, spayed and neutered dogs were also more likely to develop behavior disorders than intact dogs.

This included:

  • fear of storms
  • separation anxiety
  • fear of noises
  • timidity
  • excitability
  • aggression
  • hyperactivity
  • fear biting.
Another study found neutered dogs were more:

  • aggressive
  • fearful
  • excitable
  • less trainable than intact dogs
(Parvene Farhoody @ M. Christine Zink, Behavioral and Physical Effects of Spaying and Neutering Domestic Dogs, May 2010)

This is contrary to the popular belief that neutering reduces aggression and other behavior problems.

There’s Nothing Routine About Spay/Neuter
These findings also present a conundrum for shelters and rescues who advocate spay/neuter.

Although reducing the number of dogs in shelters is an important goal, it’s more important to prevent them from ending up at the shelter. While most people believe that shelters are full because of over population, behavior problems are the most common reason owners give up their dogs.

Moreover, is it fair for shelters to burden adoptive families with the increased risk of cancer and joint disease?

There are alternatives to the complete removal of the reproductive organs and this might play a role in reducing the risk of cancer, joint disease and behavior issues.

Spay is “instant menopause” and immediately shuts off the supply of protective hormones that are obviously involved in much more than just reproduction. Modified spay/neuter surgeries have less impact on the hormones and endocrine system, so dogs will enjoy more protection, even when sterilized.

Hormones produced by the reproductive organs not only are essential for reproduction, but in the development of:

  • homeostasis
  • body condition
  • cholesterol levels
  • energy levels
  • urinary continence
  • muscle tone
  • cognition
  • behavior
  • and, most importantly, they also play a role in the immune system
The rise in the risk of many cancers in response to the removal of the reproductive organs is evidence of this.

I noticed the studies you cited were on medium sized dogs. It would be interesting to see how they compare to studies on small dogs.

There's no law like that in Canada that I'm aware of although shelter pets get fixed before they are adopted out. None of the chihuahuas that I had were spayed. If it ain't broke don't fix it is what I say. Of course if there is a chance for unwanted puppies or kittens it may be wise to do so.

It is broke. As long as people buy puppies just to breed them, nothing is more humane than getting every dog fixed before it is adopted.

I agree with you linda,when they first got the pups I told them not to get them spayed to early because of your information,but it seems the vets talked them into it because of the new laws,they had no intention of breeding with the dogs. Oh well I tried,I just hope they dont have problems in the future.
I know our Shephed had uti problems and cruciate ligament problems,(before she went to Rainbow bridge) probably because of spaying to early.

because the growth plates have not closes completely the legs keep growing longer, putting strain on the knees plus gives them a funny shape. They will be taller than normal for the breed and when the fill out and gain weight it puts strain on the knees resulting in injury to the ligiaments. Then the ligament tears, if its just a partial tear it will repair itself with rest, but a full tear requires then its not uncommon to blow the other knee within a year or so because when the first knee is bad the dog tends to shift their weight to the good knee weakening that one
