Which Dogs Have Bobbed Tails?

Are any dogs born with bobbed tails?

Dogs that are born without tails or with small ones fall under the category of bobtailed breeds. Responsible for the most known bobtail breeds is an ancestral T-box gene mutation (C189G). Dogs with a bobtail are naturally born with this trait and should not be confused with docking.

Why are some dogs tails bobbed?

Historically, tail docking was thought to prevent rabies, strengthen the back, increase the animal's speed, and prevent injuries when ratting, fighting, and baiting. Tail docking is done in modern times either for prophylactic, therapeutic, cosmetic purposes, and/or to prevent injury.
