oh! also! have you tried Bitter Apple? You spray it on furniture, shoes, whatever, and it deters the dog from chewing (it tastes gross). There are rare dogs who actually like the taste, but most really hate it. It worked for me! Now my dog will try to chew on something that’s been sprayed just out of principle – I can chew on this if I want to! look at me, I’m being bad! – but then he gets this grossed out look on his face, like, ugh, and if I don’t pay attention to him he stops right away.
