Maybe there was no "dog whisperer" show during his time. Dogs will listen and obey the owner only if the owner is a worthy leader who takes good care of the pack and protects them. The pack will challenge the leader if the pack feel that the leader is not capable of leading, uncaring and weak. There are already many warning signs . If he believes in folk tales that once trained, dogs will remain faithful and loyal, regardless of the situation, then it is time that he invites the dog whisperer over for a lesson on pack behavior.
