I have a new puppy and I can't get him to stop chewing my stuff up. The only exception to normal training is he is doing it when I am not around. The same goes for trash digging. He has food and gets walked and played with. He just chewed up a pair of shoes I have had for 4+ years and I don't know what to do. I can't punish him because he won't know what I am punishing him for. Dog experts help me please. I know associating a barrier around things he should stay away from is what I should do but the trash can is in the kitchen on the way to his dog door.
