I have two puppies ones my grandma's and ones mine and no matter what I do they still want to chew on the carpet wooden things and our underwear. I've tried everything my friend has told me to do and still doesn't work. I've tried spanking them but not hard, I've tried vinegar, I've tried positive scolding. They just won't learn not to and they are both smart just stubborn. And my dog barks at every little sound or movement. My dog is a Chihuahua/Dachshund mix that is 8 months old and my grandma's is a Dachshund that is about 4 to 5 months. I don't know if that has anything to do with anything. And they are pretty good at not peeing in the house its just pooping is more of a problem. Oh and none of them are neutered. I need some major tips and help, because we live in an apartment and we can't afford anymore damage to it. So if anyone can help me please do.
