Chewing is a very normal dog behavior that is usually healthy. Excessively destructive chewing may be a sign that something is wrong, but otherwise, expect dogs to enjoy chewing. The trick isn’t to stop them from chewing, but rather, to modify their chewing behavior so that it is appropriate, non-destructive, healthy for the dog, and not causing any problems for you.
The first step is to provide your dog with options for chewing. Chew toys should be plentiful in your home. Praise your dog when you see it chewing on one of its toys. If you find your dog chewing on something other than a toy, quickly remove the item (or the dog from the area), hand over a chew toy and praise the dog when it switches to chewing on the toy.
Help your dog learn what to chew by using flavors or scents that appropriate. Never give your dog anything to chew that smells like you- this will create an association you don’t want. Your dog can’t tell the difference between your old hiking boots and your new ones, and will begin chewing on your personal belongings. On the other hand, if you use chew toys the hide treats or rub something tasty on the outside of chew toys and bones, that will be the flavor and smell that is associated with chewing.
Use bitter apple or hot pepper spray on household items that your dog shouldn’t be chewing on- like the walls or your table. Also, remember you can’t punish your dog for chewing on something after the fact; they won’t understand why you are angry.
