Good Dog is collaborating with Canine Sports Productions to conduct a study exploring the potential effects of spay/neuter, alternative surgeries (vasectomy, ovary-sparing spay), and leaving dogs intact.

In recent years there has been great interest in the potential long-term effects of removing the gonads (the testes and ovaries) in dogs, including risk for some cancers, orthopedic conditions, and changes in behavior. As a result, some dog owners have chosen surgery for their dog that prevents breeding but leaves the gonads intact, such as a vasectomy or ovary-sparing spay (OSS).

To date, however, there is no published information on the long-term effects of these alternative surgeries. We are hosting this survey to learn more about the effects of vasectomy and ovary-sparing spay on dogs compared to the more traditional surgeries (neuter or spay) or leaving dogs intact.

By filling out this survey, you will be doing a great service to the dog world, helping people make more informed decisions about what, if any, reproductive surgery might be best for their canine companions.

Please fill out one survey for each of your current and past dogs. After filling out the survey for one dog, you can return to the link to start another survey for a different dog. The estimated time to fill out the survey for one dog is no more than 5 minutes.

 At the end of each survey, you will have an opportunity to provide any additional information you think might be important.

Intact – A dog that has not had any of its reproductive organs (ovaries, uterus, testes) removed, or a dog who has at least one testicle
Castration (neuter) – Removal of both testes
Spay – removal of both the ovaries and the uterus
Vasectomy – surgical cutting and sealing of the vas deferens
Ovary-sparing spay (hysterectomy) – removal of just the uterus, leaving the ovaries behind
Ovariectomy – removal of just the ovaries, leaving the uterus behind

First, please answer some simple questions about you and your dog.
