Chewing a destructive behavior when your dog is chewing on the wrong thing. Give him something that’s okay to chew.Puppy chewing is an important part of the teething process. As adults, dogs often chew for fun, or to relieve boredom. Chewing or tearing things up (like paper) can also be a displacement behavior, a way to release pent-up energy or stress.
Puppy proof your house. With any type of behavior you wish to change, one of the most important things to do is manage the environment. We are all familiar with “puppy proofing” our houses you learn to put shoes away and put pups in the crate when we are not watching them.
Give him a chew toy instead. If your dog is chewing on an inappropriate item while in your presence, simply re-direct him to an appropriate chew toy. Many pups have certain times of day when they are more likely to chew, so you can head this behavior off at the pass if you choose this time of day to give the dog an approved chewy.
Bad-tasting repellents and sprays. You can keep puppies and adult dogs away from some items by using impersonal correction, preferably where the “environment” does the correcting. For example, spray items with Bitter Apple spray or Boundary dog repellent, or use a Scat Mat at the edge of a counter top, to stop counter surfers. This type of training operates on the same principle as a child touching a hot stove – if something is particularly unpleasant, most likely the child or the dog will make the decision not to repeat that behavior.
