Spayed bitches

I'm afraid your vet is right Jo and spayed bitches can and do have a bladder incontinence problem. It's the loss of oestrogen that is the cause and the vet can give you medication which will improve the situation. I suppose it's like HRT! I know because my little springer suffered from it. We did give her medication for a time but for some reason it improved after a while and she didn't need it. There are in fact notices up in our vets explaining the possible after effects of spaying.
