To Neuter/Spay or Not? Cancer?

"In a study of 745 purebred rottweilers, Dr. B. C. Beranek and colleagues from the departments of veterinary clinical science and veterinary pathology found that 15% of all the dogs developed bone cancer. However, the risk of bone cancer was 65% higher for castrated males and 34% higher for spayed females."

Further on in this study,

 it was noted the risk of cancer in Rotties neutered before 18 months was higher than it was after that age.

Dr. Mary Wakeman, a specialist in canine reproduction: "The situation in dogs (male dogs), is not equivalent.

It is no longer medically justifiable to castrate dogs for prevention of cancer.

The overwhelming mass of data to the contrary can no longer be ignored, and

publications are out there so that no veterinarian can use the excuse of ignorance.

 Castration predisposes to highly malignant prostatic cancer.

Nearly all ogs afflicted with this nasty tumor are neutered individuals.

Testicular cancers are very rare and almost always benign.

Perianal adenoma can be treated by castration if and when it arises.

It too is benign although messy."

 

 

My feelings on the subject are that neutering/spaying should be something each caregiver gives serious thought to before making this decision.

If you are going to have this sugery performed make sure you consider all of the possiblities before making this decision.

I recommend you at least let them have two or three seasons before spaying

and for males I recommend you wait until they are two years old if at all possible.
