Chewing on the Furniture
Puppies are just like small babies. They like to chew on things to get rid of the pain from teething. If your pet is chewing on furniture and different things like this when he is no longer a puppy, it could mean something else. That doesn’t mean the dog is badly behaved or trying to destroy everything.
This could just mean that they need more physical activity and probably need to be taken out more to release their energy. Start with a walk and go from there. You can also try to take them to a dog park so they can run around more freely.
