Now here is one such study out of Sweden, you will recall that Sweden does not allow s+n unless for medical reasons: Breed variations in the incidence of pyometra and mammary tumours i... - PubMed - NCBI This study shows a rather large cross section of dogs - info gleaned from I believe an Insurance company. It shows a higher rate of both mammary cancers and pyrometra than I have seen in North American studies. And as the abstract was only available to me, I don't know if that study only looked at 2 health concerns.
Again the decision to s+n should be a well thought out one, taking into account the breed you own, your particular dog and a comprehensive understanding of all risks vs benefits. |
No it's not anecdotal. Her vet told her this was the reason: lack of spay. Since he is a surgeon in a large vet hospital, I think he would know. Similarly, the dog's oncologist also agreed. I guess they're lying???
