Just back from the vets with my 11 month setter and been told that as his testes hadn't yet descended he would need an op.
Vet said that as I bought him when he was four months old I should have been advised of this as it can cause problems for the dog and that the breeder would have been advised of this by her vet when doing inoculations.
I can't believe I never noticed either, always had bitches.
Do you think the breeder should have made me aware of this?
