Selective breeding of various Bull, Mastiff and even English Lab in the beginning breeds has created an ultimate companion Bull breed dog. A medium energy, friendly, loyal, low prey drive, trainable, healthy, sturdy, non-game bred dog. They can be used to pull farm equipment, non vicious guard, for search, as service dogs, or just kept as a pet and walking buddy. Human and dog aggression is not characterstic or tolerated. Can have blue, brown, heterochromatic eyes. #ultimate #bulldog #dog #bully
