When to spay?
We have a 6 month old Nova Scotia Duck Tolling Retriever.
Our vet wants to spay her.
Our breeder says we have to wait until she has her first heat or 1 year, whichever comes first.
Vet says there is a high risk of Mammary tumors if we wait (googled and found it goes from 0.5% to 9% if not spayed before 1st heat)
Breeder says she hasn't seen problems with breeding dogs; but spaying early causes joint problems and urinary incontinence.
Vet says there are some reports of that, but it is not conclusive. Besides, they can be treated while mammary tumor likely can't be.
It is so confusing. I am leaning to 8 months; should miss the first heat, but will give 2 extra months for development.
Any strong opinions?
