First, know that most dogs learn their chewing behaviours as puppies. When teething, they seek out anything in sight to chew on. Owners who give them old socks, shoes, or toys from the house are basically telling them that those items are okay. If your adult dog is constantly raiding your closet for shoes or old t-shirts, try to remember if you did this when they were young.

Even if you did not give your puppy household items to chew on, you‟ll need to retrain them to understand that those items are not okay to chew on. Simply yelling at the dog will almost never have a positive impact. They are doing something natural and until you show them that your belongings are not okay to chew on, the behaviour will not stop.
To start, you may consider crate training your dog.

By removing the dog from an environment as large as your home, you can control what they do when you‟re not home. To that end, when you are at home, make sure you have a chewing substitute to hand them when they start chewing on a shoe, or a cushion, or whatever else in

your home they gravitate towards. A rawhide is often a good substitute if they like leather, fabric, or suede. Some dogs are partial toward rawhide, however, so you may want to take them to the pet store with you and have them choose a chew toy from the racks there.
