I agree. "de-sexing" - what sort of a term is that? - at 3 months old is cruel. In which country is this done?How can you say that? No dog should be neutered until it is fully mature, it's cruel. No vet I know would do that just for convenience. For a bitch it is major surgery.Why is this one of the "worst" and strangest things to do to a dog? Many puppies are desexed before they leave the breeder, meaning they are desexed at 3 months of age. Not strange at all, widely accepted and im sure this is not one of the worst surgical interventions a dog must endure.One of the worst is neutering at 4 months old. For convenience
