My 9yo lab has been neutered this morning. He came to us at 3 and a half, having been left entire by previous owner. The vet at the time advised us that neutering him at that age carried as many risks as advantages (which I now realise isn't exactly true), so we left it. About 3 weeks ago he developed an abcess on his prostate, fortunately he is getting better and the vet (we've changed practice recently) recommended having him done.
That's the background anyway
now for the actual question - I picked him up about 3 hours ago, he seems OK, just sleepy. The vet hasn't given us a cone for him to wear, the dog hasn't really shown any interest or licked the area as yet, but would it be a normal practice to maybe put him in a cone just in case? I don't know, as he's not had any surgery before, and didn't think to ask at the time.
