Why don Doberman Pinschers tails grow?
A doberman’s natural tail is actually long. Many owners and breeders decide to have their tails docked (shortened) while they are puppies to give them the traditional doberman appearance. Also, if the dog is to be trained as a guard dog having the tail docked serves a purpose. During a physical engagement (fight) the dog’s tail is more difficult to grab thus making it hard to defend against the dog.
