I have searched and searched for one on my favorite stories but can't remember the title and can find it. Help me if you know the title. It is a story about a guy who takes a dog to the Vet and sees porn on the vets computer, He ends up castrated and used by the dogs in the kennel. Becoming a bitch to his dog and many others. thanks

It sounds like Will it hurt? by Artistic Licence. A boy goes to the vet with his dog and get castrated himself, that is the first part. Someone else wrote a second part, which I don't know.
