Please help! I have the most wonderful dog, she obeys in the house and never is aggressive with any of us. Until someone comes to our door or when she escapes outside! She barks and lunges at the door if someone knocks. And today she slipped through the front door and actually bit my neighbor on the heel. My neighbor was in her own yard!
I do not want to have to put Lupe to sleep. But I'm afraid I will have to do it if I can't change her behavior.
