Stop Inappropriate Chewing
If you see your dog chewing on something they shouldn’t, take it away from them immediately and scold them. Then, present them with a proper chew toy and praise them. This will teach your dog the difference between what they can and cannot chew. You can also apply bitter apple as a taste deterrent to items that you cannot store away from the dog. It’s not going to be an easy process, especially with puppies, but being persistent and taking away all inappropriate items will eventually get through to the dog.
