The evidence shows that spay/neuter correlates with both positive AND adverse health effects in dogs. Breed, age, and gender are variables that must be taken into consideration in conjunction with non-medical factors for each individual dog. Please support the hard working holistic vets who make this information possible. And there is an increased incidence of mammary cancer in unspayed female dogs and a pretty high rate of uterine infection as well.

Does it justify the anger and opposition that meets me and anyone else who openly discusses the medical risks to spaying and neutering? Although this summary specifically analyzes the effects of spaying and neutering on a dog’s risk to develop osteosarcoma, the study also conducts other in depth case studies pertaining to other prevalent diseases.

Mammary tumors in dogs have been found to have estrogen receptors17, and the published research18 shows that the relative risk (odds ratio) that a female will develop mammary cancer compared to the risk in intact females is dependent on how many estrus cycles she experiences: The same data when categorized differently showed that the relative risk (odds ratio) that females will develop mammary cancer compared to the risk in intact females indicated that: Age at Spaying                      Odds Ratio, ≤ 29 months                               0.06, ≥ 30 months                               0.40 (not statistically significant at the P<0.05 level) Intact       1.00. 57: 545-548, 1976.

Pet owners, animal advocates and veterinarians should be able to talk about them openly and honestly. Based on their results, the researchers suggest a cause-and-effect relationship: “this suggests that castration does not initiate the development of prostatic carcinoma in the dog, but does favor tumor progression”5 and also “Our study found that most canine prostate cancers are of ductal/urothelial origin….The relatively low incidence of prostate cancer in intact dogs may suggest that testicular hormones are in fact protective against ductal/urothelial prostatic carcinoma, or may have indirect effects on cancer development by changing the environment in the prostate.”6.
