I have a 7 month old puppy mix breed. Not sure what he is but I attached a picture. He's about 16 lbs now.
Training is going very well so far. He is energetic and very friendly. He loves people and other dogs. He is comfortable with us opening his mouth for checkups. He rarely shows signs of aggression.
The Problem Is:
When he is chewing something he shouldn't be chewing, there is no way to stop him! He growls, gets very aggressive and will bite if I don't stop. I have tried tilting his head down and applying pressure to his lips by his rear teeth. I have tried using a treat as motivation to drop what he is chewing... Nothing.
Does anyone have any other suggestions or success stories?
