Delayed Spaying and Breast Cancer

[SusanneS]

Does delaying spaying increase risk of breast cancer in female dogs?

Glad you have the forum working for you, Susanne.
No, it does not. @Dr. Jean Hofve will have some study information.
And, of course, building and maintaining a healthy vital force is the best prevention.

Yes. Spaying provides protective effects against mammary cancer in dogs, and it's most protective if done before first heat cycle. However, spaying has negative effects in other areas, especially in larger dogs. As Dr. Christina said, the best defense against all kinds of health issues is a strong vital force.

My daughter's Chihuahua is 15 months and she has had 2 heat cycles already so I hope we haven't placed her at risk of breast cancer later on. Anyway, we will get her spayed ASAP. Does every heat cycle increase the risk?

I guess it does increase risk according to Jean's post.
