Destructive Chewing in Dogs
Normal Chewing Behavior
Chewing is a perfectly normal behavior for dogs of all ages. Both wild and domestic dogs spend hours chewing bones. This activity keeps their jaws strong and their teeth clean. Dogs love to chew on bones, sticks and just about anything else available. They chew for fun, they chew for stimulation, and they chew to relieve anxiety. While chewing behavior is normal, dogs sometimes direct their chewing behavior toward inappropriate items. Both puppies and adult dogs should have a variety of appropriate and attractive chew toys. However, just providing the right things to chew isn’t enough to prevent inappropriate chewing. Dogs need to learn what is okay to chew and what is not. They need to be taught in a gentle, humane manner.
- “Dog-proof” your house. Put valuable objects away until you’re confident that your dog’s chewing behavior is restricted to appropriate items. Keep shoes and clothing in a closed closest, dirty laundry in a hamper and books on shelves. Make it easy for your dog to succeed.
- Provide your dog with plenty of his own toys and inedible chew bones. Pay attention to the types of toys that keep him chewing for long periods of time and continue to offer those. Try Nylabones®, Greenies® Smart Chew™ bones, Dental KONGs® and natural bones. It’s ideal to introduce something new or rotate your dog’s chew toys every couple of days so that he doesn’t get bored with the same old toys. (Use caution: Only give your dog natural bones that are sold specifically for chewing. Do not give him cooked bones, like leftover t-bones or chicken wings, as these can splinter and seriously injure your dog. Also keep in mind that some intense chewers may be able to chip small pieces off of natural bones or chip their own teeth while chewing. If you have concerns about what’s safe to give your dog, speak with his veterinarian.)
- Offer your dog some edible things to chew, like bully sticks, pig ears, rawhide bones, pig skin rolls, other natural chews, Dentastix®, Dentabones® and Nylabone® Healthy Edibles® bones. Dogs can sometimes choke on edible chews, especially if they bite off and swallow large hunks. If your dog is inclined to do this, make sure he’s separated from other dogs when he chews so he can relax. (If he has to chew in the presence of other dogs, he might feel that he has to compete with them and try to quickly gulp down edible items.) Also be sure to keep an eye on your dog whenever he’s working on an edible chew so that you can intervene if he starts to choke.
- Identify times of the day when your dog is most likely to chew and give him a puzzle toy, such as a KONG®, Squirrel Dude™, Twist ‘n Treat™ or Buster® Cube, filled with something delicious. You can include some of your dog’s daily ration of food in the toy.
- Discourage chewing inappropriate items by spraying them with chewing deterrents. When you first use a deterrent, apply a small amount to a piece of tissue or cotton wool. Gently place it directly in your dog’s mouth. Allow him to taste it and then spit it out. If your dog finds the taste unpleasant, he might shake his head, drool or retch. He won’t pick up the piece of tissue or wool again. Ideally, he will have learned the connection between the taste and the odor of the deterrent, and he’ll be more likely to avoid chewing items that smell like it. Spray the deterrent on all objects that you don’t want your dog to chew. Reapply the deterrent every day for two to four weeks. Some commonly used deterrents are Grannick’s Bitter Apple® spray or gel, Veterinarian’s Best® Bitter Cherry Spray, Yuk-2e Anti-Lick Gel, Bitter YUCK!™ No Chew Spray, Chew Guard® Spray and Tabasco® sauce. Please realize, however, that successful treatment for destructive chewing will require more than just the use of deterrents. Dogs need to learn what they can chew as well as what they can’t chew. Please see our article, Using Taste Deterrents, for more information.
- Do your best to supervise your dog during all waking hours until you feel confident that his chewing behavior is under control. If you see him licking or chewing an item he shouldn’t, say “Uh-oh,” remove the item from your dog’s mouth, and insert something that he CAN chew. Then praise him happily. If you suspect that your dog might react aggressively if you remove an item from his mouth, please see our Finding Professional Help article for information about finding a Certified Applied Animal Behaviorist (CAAB or Associate CAAB), a board-certified veterinary behaviorist (Dip ACVB) or a Certified Professional Dog Trainer (CPDT) with specialized training in treating aggression for guidance.
- When you can’t supervise your dog, you must find a way to prevent him from chewing on inappropriate things in your absence. For example, if you work during the day, you can leave your dog at home in a confinement area for up to six hours. Use a crate or put your dog in a small room with the door or a baby gate closed. (For help with crate training, please see our article, Weekend Crate Training.) Be sure to remove all things that your dog shouldn’t chew from his confinement area, and give him a variety of appropriate toys and chew things to enjoy instead. Keep in mind that if you confine your dog, you’ll need to give him plenty of exercise and quality time with you when he’s not confined.
- Provide your dog with plenty of physical exercise (playtime with you and with other dogs) and mental stimulation (training, social visits, etc.). If you have to leave your dog alone for more than a short period of time, make sure he gets out for a good play session beforehand.
- To help your dog learn the difference between things he should and shouldn’t chew, it’s important to avoid confusing him by offering unwanted household items, like old shoes and discarded cushions. It isn’t fair to expect your dog to learn that some shoes are okay to chew and others aren’t.
Some puppies and juvenile dogs like to chew dirty underwear. This problem is most easily resolved by always putting dirty underwear in a closed hamper. Likewise, some puppies and dogs like to raid the garbage and chew up discarded sanitary napkins and tampons. This can be very dangerous. If a dog eats a sanitary item, it can expand while moving through his digestive system. Discard napkins and tampons in a container that’s inaccessible to your dog. Most young dogs grow out of these behaviors as they mature.
