Destructive Chewing in Dogs
It's normal for puppies and dogs to chew on objects as they explore the world. Chewing accomplishes a number of things for a dog. For young dogs, it's a way to relieve pain that might be caused by incoming teeth. For older dogs, it's nature's way of keeping jaws strong and teeth clean. Chewing also combats boredom and can relieve mild anxiety or frustration.
Rule Out Problems That Can Cause Destructive Chewing
Dogs who chew to relieve the stress of separation anxiety usually only chew when left alone or chew most intensely when left alone. They also display other signs of separation anxiety, such as whining, barking, pacing, restlessness, urination and defecation.

Some dogs lick, suck and chew at fabrics. Some experts believe that this behavior results from having been weaned too early (before seven or eight weeks of age). If a dog's fabric-sucking behavior occurs for lengthy periods of time and it's difficult to distract him when he attempts to engage in it, it's possible that the behavior has become compulsive. If you think this might be the case with your dog, please see our article, Finding Professional Help, for information about finding a Certified Applied Animal Behaviorist (CAAB), a board-certified veterinary behaviorist (Dip ACVB) or a Certified Professional Dog Trainer (CPDT) with specialized training and experience in treating compulsive behavior. You can also learn more about compulsive behaviors by reading our article, Compulsive Behavior in Dogs.
A dog on a calorie-restricted diet might chew and destroy objects in an attempt to find additional sources of nutrition. Dogs usually direct this kind of chewing toward objects related to food or that smell like food.
