:roll: I have an 8 week old american pit terrier, he is a good dog at times, but he is really spoiled, which is my fault. Lately, while trying to train him, I notice that he growls or barks at me when I try to discipline him. I use strong voice commands, and a lite spanking with the newspaper. He is showing signs of aggression and I don't want it to get worst. Suggestions please!
