Destructive Chewing: The Complete Guide to Why Your Dog Destroys Things and How to Fix It

Why Your Dog Chews Up Your Stuff

Before we talk about the fix, we need to be clear about one thing: chewing is not a behavior problem. Chewing is a normal, healthy, necessary dog behavior. The problem is not that your dog chews. The problem is that he's chewing the wrong things — your things, instead of his things.

Dogs chew for four overlapping reasons, and most destructive chewers have more than one:

1. Teething. Puppies lose their baby teeth between 4 and 7 months of age. The adult teeth are pushing through, the gums hurt, and chewing is the only thing that relieves the pressure. The veterinary behaviorists at the American College of Veterinary Behaviorists (ACVB) — the board-certified specialists who wrote the consensus guide Decoding Your Dog — note that teething-driven chewing is intense, focused on hard surfaces, and is temporary.
2. Boredom and under-stimulation. A dog with no job will find one. Jane Arrowsmith's The Dog Behavior Answer Book calls this the "enrichment audit" problem. The dog is not "being naughty." The dog is not "getting back at you." The dog is a working animal who has nothing to work on, so he is working on your coffee table.
3. Anxiety. Separation anxiety, noise phobia, generalized anxiety, fear of a specific room or trigger. An anxious dog chews to self-soothe. The chewing is a coping mechanism, not a misbehavior. Decoding Your Dog lists "medical rule-out; teething; provision" as the first three things to address in any destructive chewing case.
4. Insufficient exercise. Mike Ritland, the former Navy SEAL and founder of Team Dog, has a clean version of the rule: "A tired dog is a good dog." A dog with pent-up physical energy will discharge it the only way available — usually on the nearest object that is not bolted down. The chewing is not the cause. The chewing is the symptom.

Your job this week is to figure out which of those four is driving your dog's chewing — and often it's a combination. The fix is the same in all four cases, but the priority is different.

First: See Your Vet

This is the step most owners skip, and for a chronic chewer, it matters. The ACVB is explicit: any sudden change in chewing behavior, any chewing focused on a specific body area, or any chewing that comes with vomiting, diarrhea, or weight loss needs a vet appointment first.

There are real medical drivers of destructive chewing. Dental disease can cause a dog to chew obsessively to relieve oral pain. Gastrointestinal issues can make a dog chew on inappropriate objects (a behavior called pica). Nutritional deficiencies, while rare in dogs on commercial diets, can drive chewing on rocks, dirt, or wood. Hypothyroidism, cognitive decline in older dogs, and partial seizures can all present as new or escalating chewing. Have your vet rule those out, especially if the chewing started suddenly or the dog is chewing on strange objects. A dog who's chewing because he's in pain is a medical patient, not a training problem.

One more vet reason: if your dog is chewing and swallowing non-food items, the next emergency surgery may be a foreign body obstruction. Strings, socks, rocks, and small toys are the most common offenders. The chewing itself is a behavior problem. The swallowing is a life-threatening medical problem.

The "Just Give Him a Bone" Myth (And Why It Backfires)

You've been told to give the dog a bone, a Kong, a Nylabone, or a bully stick and the problem will solve itself. Sometimes that works. Most of the time, it doesn't — and here's why.

Arrowsmith's enrichment audit framework is the cleanest version of the rule. The dog needs four things every day: physical exercise, mental exercise, social contact, and an outlet for normal species-typical behaviors (which for a dog includes chewing, sniffing, and digging). Giving a dog a bone satisfies one of the four. The other three are still unaddressed. The dog who is bored, under-exercised, and lonely will ignore the bone and eat the sofa.

Ritland puts it the other way. "The dog doesn't have a problem. The dog's needs are not being met." That sentence reframes the entire fix. You are not training the dog to stop chewing. You are giving the dog a life full enough that chewing your stuff is no longer the most interesting option.

"The dog doesn't have a problem. The dog's needs are not being met." — Mike Ritland, Team Dog

There is also a management problem most owners miss. Decoding Your Dog is clear: "Insufficient management" is one of the most common reasons behavior programs fail. The owner who leaves a 6-month-old Labrador unsupervised in the living room for 4 hours is not running a training program. The owner is running an experiment to see what gets destroyed next. Management is not a substitute for training. It is the foundation that makes training possible.

The 4 Body-Language Cues That Mean a Chewing Episode Is Coming

You can usually predict a chewing episode 30-60 seconds before it starts. Here is the sequence:

1. The dog disengages from you. Eyes come off you, the body turns away, the dog moves toward the object in question. This is the "I have an idea" moment. The dog is not being sneaky. The dog is doing what comes naturally.
2. The investigative sniff. A short, focused sniff at the object. The dog is gathering information: is this food, is this a toy, is this something new?
3. The lip-lick and pause. Patricia McConnell, the applied animal behaviorist who wrote The Other End of the Leash, lists lip-licking as one of the four stress signals. In this context, it's also a "I'm about to commit" moment. The dog has decided to chew and is about to start.
4. The first mouth-contact. The dog puts his mouth on the object. This is the moment to interrupt. A calm "ah-ah" and a redirect to a legal chew. Not a yell, not a chase, not a scruff-shake. A neutral interruption and a swap to the right thing.

If you see cues 1-2, you can redirect before the chewing starts. The cleanest fix is the one that prevents the chew, not the one that interrupts it.

The Fix: The Four-Part Plan

Every effective method for reducing destructive chewing shares four parts, McConnell and the ACVB agree: manage the environment, meet the dog's real exercise needs, give the dog mental work, and supervise. Here is the plan:

Part 1: Management (The 24-Hour Fix)

Management is the part most owners skip and the part that makes everything else work. The rule: if you cannot supervise the dog, the dog cannot have access to the wrong things. That means:

• Crates, exercise pens, or baby gates for the times you can't watch.
• Shoes, books, remote controls, kid toys, socks, and any small chewable object put away or behind closed doors.
• The dog is not "trusted" until the chewing is gone. Trust is earned over months, not assumed at the start.
• Rotating the dog's access to different rooms. A dog in the kitchen can't chew the living-room rug.

Arrowsmith is clear: "The first 2-4 weeks should be 90% management and 10% training." Set the dog up to succeed. Do not test the dog by leaving the wrong thing in the wrong place at the wrong time.

Part 2: Real Exercise (Not Just a Backyard)

Ritland's "a tired dog is a good dog" is not a cute saying. It is a training principle. The dog who is destructive at 3pm is the dog who did not work off his morning energy. The minimum daily exercise budget for a working breed (Lab, Shepherd, Border Collie, Husky, etc.) is 90 minutes of real physical activity — on-leash walking or jogging, off-leash fetch, swimming, flirt pole. For a low-energy breed (Bulldog, Basset, Greyhound) it is less, but it is never zero. If your dog is destructive, the first question is "is he actually tired?"

Note: yard time is not exercise. A dog left in a backyard is usually lying near the door, waiting to come back in. He is not running laps. He is not burning energy. He is not tiring himself out. For a real exercise effect, the dog needs structured activity with you.

Part 3: Mental Enrichment (The Chewing Cure)

This is the part that has the biggest impact on chewing. Arrowsmith's "enrichment audit" — logging how much physical exercise, mental exercise, social contact, and chewing the dog gets per day — is the diagnostic. The fix is to add mental work in five forms:

1. Long-lasting chews. Stuffed Kongs, frozen lick mats, bully sticks, Himalayan chews, raw bones (supervised). Rotate them so the dog doesn't get bored with the same one.
2. Food puzzles. Snuffle mats, Nina Ottosson puzzles, frozen toppl, scatter-feeding in the yard. The dog spends 20-60 minutes working for his meal.
3. Scent work. Hide treats around the house or yard. Let the dog find them. Patricia McConnell: "Let them use their nose — that's their primary sense." A 10-minute scent game tires a dog more than a 30-minute walk.
4. Trick training. Teach a new behavior every week. Sit, down, paw, spin, crawl, roll over, get a toy, put it away. The mental work is the point.
5. Sniff walks. A walk where the dog is allowed to sniff everything he wants to sniff. The mental work of processing a thousand smells tires a dog's brain as effectively as a run tires his body.

The combination of physical exercise plus mental enrichment is what Ritland calls the "daily ration in the pouch" approach. The dog has a job. The dog has a tired body. The dog has a tired brain. The dog is not interested in your shoes.

Part 4: Supervise and Redirect

When you are home and the dog is loose, you are supervising. That means: eyes on the dog, treats in the pouch, and a plan for the moment the dog wanders toward something he shouldn't have. The "trade-up" method is the cleanest redirect: when the dog picks up the wrong thing, calmly offer a high-value chew in exchange, take the wrong thing away, and reward the dog for letting it go. The dog learns: chewing my toys gets me treats. Chewing your stuff gets me treats too, but only if I give it back. Trade, don't punish.

When to Call a Professional

If the chewing is focused on doors, windows, or the area where you leave the house — and only happens when you're gone — that's separation anxiety, not a chewing problem, and the fix is different. If the chewing is escalating despite consistent management, if the dog is injuring himself (broken teeth, broken nails, mouth lacerations), or if the chewing comes with other anxiety signs (pacing, panting, drooling, escape attempts) — get help. The ACVB tier system:

• Board-certified veterinary behaviorist (DACVB) — the gold standard for anxiety-driven chewing, compulsive chewing, and cases where medication may be part of the plan. This is a vet with 4+ additional years of behavior specialty training.
• Certified Applied Animal Behaviorist (CAAB) — PhD-level non-vet behaviorist. Also excellent for chronic cases.
• CPDT-KA — Certified Professional Dog Trainer. Good for building an enrichment plan, training a "leave it" cue, and working with families on consistency.

That doesn't mean your dog is broken. It means the fix needs a coach. Most destructive chewing resolves in 2-6 weeks with a solid four-part plan. The chronic cases — the dog who has been chewing for months, the dog who chews through crates, the dog whose chewing has cost you a security deposit — those benefit from a professional. Your job is to manage the environment (no access, no unsupervised time) while the trainer builds the new behavior.

What To Do This Week

1. Day 1: Vet appointment to rule out medical causes — dental disease, GI issues, pica, hypothyroidism. Bring a list of what the dog is chewing, when, and any photo/video of the chewing. Note: if the dog has swallowed something dangerous, this becomes an emergency vet visit immediately.
2. Day 2: Do a full puppy-proofing sweep. Shoes up. Books up. Remote controls in a drawer. Kid toys in a basket. Cords covered or sprayed with bitter apple. Anything small enough to swallow goes away. The dog cannot be tempted by what the dog cannot reach.
3. Day 3: Buy three to five long-lasting chews. Stuffed Kongs, bully sticks, Himalayan chews, frozen lick mats. Rotate them. The dog should have a legal chew available any time he is unsupervised.
4. Day 4: Do the enrichment audit. Write down how much physical exercise, mental exercise, social contact, and chewing the dog gets per day. If any of those four numbers is low, the chewing is partly a needs problem. Fix the input before you fix the output.
5. Day 5: Set up the trade-up game. Sit on the floor with the dog. Put a low-value chew (his normal toy) on one side and a high-value chew (stuffed Kong) on the other. When he goes for the Kong, mark and reward. When he goes for the toy, mark and reward. You're building a "leave it" cue from the dog's own choices. Do this 5-10 times. End the session.
6. Day 6: Add a 10-minute sniff walk or scent game. Hide 10 treats around the living room. Let the dog find them. The mental work is what tires a dog's brain. A tired brain is the best cure for destructive chewing.
7. Day 7: Review the enrichment audit. If the four numbers are all healthy and the chewing is still happening, the dog may be anxious. Schedule a CPDT-KA or veterinary behaviorist consult. The ACVB website has a directory.

The Honest Truth

Destructive chewing is the most expensive dog behavior problem in America — between chewed furniture, eaten shoes, and emergency vet bills for foreign bodies, owners spend billions every year. And it's also one of the most-often made worse by well-meaning owners who try to "fix" it with punishment. The 50-year-old "rub his nose in it" advice persists because it's dramatic. The 30-year-old science says it doesn't work and makes the anxiety worse. The fix is a four-part plan that takes 2-6 weeks, costs less than a new sofa, and requires you to look honestly at whether the dog's needs are actually being met.

Most dogs with destructive chewing can be helped — many dramatically, in a matter of weeks. A small number of cases are anxiety-driven, and those need professional help. The deciding factor in almost every case is whether the owner commits to the full four-part plan — management, exercise, enrichment, and supervision — and stops relying on the dog to figure it out on his own.

You're not alone in this. The dog is doing what dogs do. He just needs the right things to chew. You've got this.
