(Warning: This is an extremely controversial topic that is heavily debated and more studies are on the way. This is simply the other side that is being presented. By no means is anyone advocating for irresponsible pet ownership or non-sterilization.

Yet another study confirming the link between spaying/neutering and the increase of cancer rates in pets!

Last June, we posted a study conducted on the increased rates of cancer in desexed Vizslas and methods of sterilization that help decrease the rates. The post almost broke the internet with comments. (

What we the pet owners, and the veterinarians of the medical profession, have been taught about spaying and neutering our pets early (6 months) to prevent mammary and testicular cancer seems to be all wrong, according to all the new research that is being spit out!

“… maybe what I learned in vet school about early spay/neuter was not so straightforward after all!” - Dr Sue Cancer Vet, DVM, Dip. ACVIM (Oncology)

“Sterilization increases the risk of joint disease and cancer in both golden retrievers and Labrador retrievers.” - Veterinary Practice News

“The removal of hormone-producing organs during the first year of a dog’s life leaves the animal vulnerable to the delayed closure of long-bone growth plates,” said Dr. Benjamin Hart of the UC Davis School of Veterinary Medicine.

This was in reference to the latest study conducted on spaying and neutering by the researchers at the University of California, Davis (published in the journal PLOS ONE). (

The UC Davis researchers further confirmed what previous studies have shown - intact dogs of both breeds have lower rates of joint disorders and cancer than desexed dogs.

A study conducted at the Gerald P. Murphy Cancer Foundation found: “Taking away ovaries during the first four years of life completely erased the female survival advantage. We found that female rottweilers that kept their ovaries for at least six years were four times more likely to reach exceptional longevity compared to females who had the shortest lifetime ovary exposure." (

So what other methods are there instead of desexing our pets? Research is now pointing to another direction: the possibility of sterilization.

“To sterilize without desexing. This means performing a procedure that will prevent pregnancy while sparing the testes or ovaries so that they continue to produce hormones essential for the dog's health and well-being. This typically involves a vasectomy for male dogs, and either a tubal ligation or modified spay for females. The modified spay removes the uterus while preserving the hormone-producing ovaries,” explains Doctor Karen Becker.

Dr. Becker continues: “Whenever possible, I prefer to leave dogs intact. However, this approach requires a highly responsible pet guardian. […] My second choice is to sterilize without desexing.” (

By spaying and neutering our pets, we are ripping out their parts, including their hormones, (complete removal of the ovaries and uterus in female dogs, and the testes in males) to prevent over population and behavioral problems from developing. By desexing our pets, some argue that they are no longer male nor female, as we have altered their sex. However, research is showing that our pets drastically need these hormones in order to prevent the most aggressive cancers (osteosarcoma, bladder transitional cell carcinoma, prostate cancer, lymphoma, and mast cell tumors) and other diseases from developing.

The problem is that most veterinarians do not have the proper training to conduct this not-so-new technique of sterilization and often opt for the desexing methods as demanded by pet owners. So, if this option is not available to you, what else can you do?

Quoting the world’s top veterinarian Cancer Doctor, Dr. Damian Dressler ( “Most dogs reach sexual maturity at about 24 months approximately at the fourth heat in females at this point in their development dogs have received the protective benefit of adult sexual hormones and are at a decreased risk for cancers mentioned above.

If you choose to spay or neuter your dog my general recommendation is to spay females sometime between the third and fourth heats which will have the added benefit of reducing the risk of mammary cancer and neuter males sometime between the ages of 18 and 24 months.” (

I write this blog for one reason and one reason only. I do not want to promote irresponsible pet ownership and overpopulation. I do, however, want to encourage you, the pet owner, to make the right decision for you and your pet. In order to do so, you need to know all the facts! Today, the cancer rate is 1 in 2 dogs and 1 in 3 cats. It’s time we better ourselves.

This is an X-ray of a 2 week old puppy. 

Look at how far the bones have to grow before they become a proper bony joint! This is why you should never let puppies jump, walk up/down stairs, over exercise or over train. Doing to much impact activity at a young age will cause serious issues later in life, or even at a young age as hip dysplasia and other orthopaedic conditions are rising in puppies! 
Remember the puppy rule for every month increase activity by 5 minuets! For example an 8 week old puppy only needs 10 minuets physical activity a day - a 6 month old only needs 30 minuets a day of physical activity!!
*physical activity includes - going for a walk, training, playing fetch, running, playing with other dogs etc. Genetic testing is only going to tell us so much. So do not allow your puppy to jump off of things, and do not allow high impact sports before 6 months old. Make sure they have a proper diet with good food (not Ole roy). Keeping their weight ideal helps for growth and structure. Don't allow them to be over weight but also Make sure nutrition is kept well or they can lose bone density and muscle mass when malnurished. Later spay/neuter to help make sure their hormones develop their muscles and bones to support each other. We as breeders try to create sound healthy puppies. But it's up to you as new pup parents to make good choices regarding your pups health once they are in your care! Don't be afraid to use your breeders knowledge. Ask them questuons.Thats what they are there for. 

Enjoy your new puppy but remember you wouldn't make a 6 month old baby run a mile a day so don't make your puppy either!
