Hi all, a friend of mine had a dog of me 3 years ago, about 18 months ago he got the smell of a bitch in season, and spent about three days going crazy trying to find her, my friend decided to have him done 12 months ago and all went well, however last week he had her up in the night scratchin the door crying, just would not settle exactly the same as before the op, she took him for a check to the vets and all was fine.
So has anyone heard of this before, or his he just a very horny boy..lol

I have several castrated male dogs, and they haven't changed at all, they still mate and tie with in season bitches given half a chance, so not all that unusual. :)
