These aren't my dogs. But I do know the breeder. I've been to his kennel about 5 plus hours away from me. He believes that the presa is first a working dog. He also competes with his dogs on Conformation. I this scenario 2 dogs were sent to take down a specific person and ignore the other person nearby. The dogs do not allow that barrier to stop them. The dogs had to work together. I have been impressed with Travis and his dogs.
