Are you giving excuses for your dogs bad behavior? Ex. "Well, he only bit you cause he was scared!", "He's only food aggressive because he thinks he won't get anymore!", "My dog only barks at other dogs on a walk because he just wants to play with the other dog!". If you are doing this, STOP! The harsh reality is you are only protecting your dog's failure. You are only encouraging him to do the wrong thing. Teach your dog the right way to behave. CORRECT what is not acceptable and reward behaviors you want. Protect your dog's success, NOT his failures!
