cats

They can still bark, or at least the one dog I've met that had it done to it could, it just sounded more like a cough than a bark.

It's often looked down on as unnecessary surgery, as it does nothing to address why the dog was barking to begin with. There are some groups that support it, as it can be looked at as something that can allow the dog to be out in public without being considered a nuisance or as a procedure that can prevent the dog from being put down.
