Why Do People Dock Dogs Tails. In the early times in england, this procedure was done because dogs’ tails were taxed. Many people believed that a dog’s tail helped the dog to run and hunt.

With a docked tail, none of this would be possible. Some breeds of dogs have a natural tendency to tuck their tails beneath them when they are scared, anxious or in pain. Other historical reasons for tail docking include strengthening the dog’s back, preventing bites during fights, and improving running speed.
