How Do You Stop a Dog Chewing Everything?

The dog who chews the sofa leg at 6 months is rarely the same problem as the dog who chews the door frame at 3 years old. The damage looks identical. The fix does not.

Work out which dog you have, and it is usually quicker than you fear.

Why Does My Dog Chew Everything?

A splintered corner of the coffee table, and a dog looking delighted with itself. Dogs chew for 6 reasons: teething, exploration, boredom, stress (including being left alone), hunger or an unbalanced diet, and habit.

Chewing is normal. It releases tension and exercises the jaw, and it is never spite; the PDSA calls that idea a myth.

Teething is the one most owners meet first. A puppy’s gums ache while 42 adult teeth push through, and a good chew eases that ache.

Exploration comes next. Dogs investigate with their mouths, so a new dog will taste the table leg, the rug fringe and the skirting board at least once.

Boredom is the big one between 1 and 3 years old. An adolescent Labrador who has had a 20-minute walk and then 8 hours of nothing has energy to spend, and the cushion is the nearest thing that gives way.

Stress is the quietest cause. A dog who chews only when you are out, and goes for doors and sills rather than toys, is telling you it is about your absence.

Hunger shows up as chewing wood or cardboard before meals. Habit is a dog returning to one spot long after the original reason has gone.

Which of those is your dog?

When Do Puppies Stop Chewing?

Around 6 months, the worst of it eases. By then all 42 permanent teeth are through and the 28 milk teeth have gone.

Milk teeth arrive from about 3 weeks, are all in by 6 weeks, and start falling out at around 12 weeks. VCA’s veterinary guidance has the full timeline.

So 12 weeks to 6 months is peak chewing, landing in the same weeks you are working out how to toilet train a puppy and surviving the “land shark” phase.

Then comes the surprise at 7 to 12 months, when the chewing returns. This time it is not about teeth. The teeth are in.

It is about a bigger dog with a stronger jaw, more energy, and 3 months of learning that chewing is fun. You are shaping a habit now, not waiting out a growth stage.

Same plan, different reason.

Puppy chewing usually travels with puppy mouthing, and both respond to the same redirect-and-reward routine. The approach for stopping puppy biting and nipping is the one you will use on the skirting board.

Is Puppy Chewing Different From Adult Destructive Chewing?

Yes, even when the teeth marks look the same. Puppies chew because of teething and curiosity, whether or not you are home, and they go for whatever is nearest.

Adult chewing is about boredom, stress or habit, usually happens when the dog is alone, and often targets exits or things that smell of you.

Notice when it happens, what gets chewed, and whether the dog takes a toy when offered one. A 4-month-old spaniel who gnaws the chair leg while you cook, then happily takes a frozen carrot, is teething.

A 2-year-old collie who shreds the post only on the days you are out for 5 hours, and ignores the toys you left down, finds being alone hard.

Sound like anyone you live with?

Rescue dogs often arrive with a third pattern: chewing learned in another home and never redirected. That is habit, and it responds to the patient work you would use when training a rescue dog who arrives with old habits: management first, correction never.

Now for the bit you can actually do something about.

How Do You Stop a Dog Chewing Furniture and Skirting Boards?

Five steps. Stick with them for 2 to 4 weeks and the habit changes.

1. Dog-proof first. For 2 to 4 weeks, the dog only has unsupervised access to a room where the worst thing available is a toy. A dog cannot practise a habit on a table leg it cannot reach.
2. Provide legal outlets every day. Put down 2 or 3 chews the dog is allowed, and rotate them. Never hand over an old shoe or sock; dogs cannot tell the retired trainer from the new pair by the door.
3. Swap and reward. When you catch the dog on the sofa arm, say its name in a normal voice, offer the legal chew, and praise the moment teeth land on it. Do not grab the forbidden item out of the mouth. The dog learns that giving something up gets it something better.
4. Freeze things. A wet flannel twisted and frozen, a rubber toy stuffed and frozen overnight, or a chilled carrot gives sore puppy gums the cold pressure they want.
5. Tire the brain, not just the legs. Ten minutes of sniffing and problem-solving takes more out of a dog than a second lap of the park.

A bored dog and an anxious dog leave the same mess but need different things.

Notice that none of those fixes involves telling the dog off.

Why Does Punishing a Dog for Chewing Backfire?

Because dogs connect a telling-off to whatever is happening right now, not to the damage done an hour ago. Tell a dog off when you walk in, and it learns that your coming home is unpleasant.

Grabbing things out of the mouth goes badly too. In one survey of ordinary pet dogs, forcing an item from the mouth got an aggressive response from 39% of them (Herron, Shofer and Reisner, Applied Animal Behaviour Science, 2009).

There is a quieter cost too. The PDSA points out that punished dogs “will probably learn to hide their chewing by doing it when you are not there, rather than stopping”.

The habit does not end. It moves to the hours you cannot see.

And the “guilty look” is not guilt. The lowered head and flattened ears are appeasement, a dog trying to switch off the storm.

Your favourite trainers were chewed because they smelled most of you. Tidy up, breathe, and plan for next time.

What Should You Do When Your Dog Chews While You Are Out?

You come home to a gnawed door frame and a perfectly intact chew toy. That is a dog struggling with your absence, and the RSPCA lists chewing and destroying furniture among the classic signs.

It starts younger than most owners realise. A long-running UK study following puppies through life, Generation Pup, found chewing, scratching at doors and howling when alone in puppies as young as 6 months.

One finding belongs on the fridge. Puppies settled in a crate or single room overnight with 9 or more hours of sleep, at 16 weeks or younger, were less likely to develop it, while puppies whose owners fussed over them on return were more likely to (Dale and colleagues, Animal Welfare, 2024).

So what does that look like on a Tuesday morning? Most of us have fussed at the door at least once.

Start with absences the dog can cope with, even 2 minutes behind a stair gate, and build up in small steps. Leave a frozen stuffed toy as you go, so your leaving predicts something good.

Then come home boring, and say hello once the dog has settled.

The RSPCA advises against regularly leaving a dog for more than 4 hours, and much less for puppies. How long can you leave a dog alone depends on the individual, and a dog chewing the door frame at hour 2 is answering that for you.

If chewing continues alongside howling after 4 to 6 weeks of steady practice, ask your vet for a referral to a clinical animal behaviourist.

Which Household Items Are Dangerous for a Dog to Chew?

The phone charger trailing off the sofa is top of the list. Live cables, batteries (especially the button cells in remotes and key fobs), medicines, cleaning products, some houseplants and cut flowers, and small things like socks that block the gut are the ones to worry about.

A chewed cable or a swallowed battery is a same-day vet emergency.

Cables come first because a live cable can injure a dog mid-chew. Cable tidies and unplugging chargers sort it in an afternoon.

Batteries are the sneaky one. A punctured battery can leak within minutes, so a chewed remote means a call to the vet, not a wait-and-see. Remotes, headphone cases and key fobs live in a drawer for the first year.

Plants are easy to forget because they were there before the dog. A 10-minute check of your windowsills against a list of flowers and houseplants that are toxic to pets settles it.

If a dog swallows wood or paint and then seems off colour, a call to the vet rules out a blockage.

Which Chew Toys Are Best for Destructive Chewers?

Try this in the pet shop aisle. Press a fingernail in: a good toy dents, and bends rather than staying rigid.

The PDSA suggests chews “soft enough to indent with your fingernail” and “bigger than your dog’s throat”. Vet dentists steer clear of anything that will not bend.

That rules out a lot of what is sold as indestructible. Antlers, hooves, hard nylon and weight-bearing bones are rigid enough to crack a tooth, and rawhide, cooked bones and anything that splinters carry a blockage risk.

Indestructible, it turns out, is a warning rather than a selling point.

The right toy also depends on how your dog chews. A Staffie and a whippet want different things. Five minutes watching your dog with a new toy tells you which row you are in.

Supervise anything new, because no chew is completely safe.

What Does a Week of Enrichment Look Like?

It looks like 10 to 20 minutes a day of sniffing, puzzling and allowed chewing, using things already in your kitchen. That uses up the mental energy that would otherwise go into the cushions.

No fancy kit required.

So where does the bitter spray by the till fit in?

Do Anti-Chew Sprays Work?

Sometimes, and only on the spot you spray. A bitter spray on one chair leg stops that chair leg being chewed; it does not stop chewing.

It is a helper, never a plan on its own.

Some dogs recoil at the first lick and never go back. A few treat it as seasoning. Reapply every day or two, because the taste fades.

How Long Does It Take to Stop a Dog Chewing?

For a boredom or habit chewer, 2 to 4 weeks of steady management. Teething chewing eases on its own by about 6 months.

Chewing when alone takes longer, typically 6 to 12 weeks of gradual alone-time training. Measure progress in minutes of calm absence rather than in undamaged furniture.

Somewhere in week 3, you notice the dog walk past the chair leg and pick up the rubber toy instead. Reward it like the best thing that has happened all day.

Two biscuits. Not the tin.

Most chewing is a phase, a habit or a message. Sort out which, remove the opportunity, and give the dog something better to do with its mouth.

Pet insurance covers unexpected vet bills for accidents and illnesses, subject to the policy terms and annual renewal. A dog who chews is a dog who occasionally swallows something it should not, which is one reason many owners look at cover while their dog is still young.

Whether cover is appropriate depends on your finances, your pet’s health profile and how much risk you are comfortable carrying yourself. You can find out more about Perfect Pet Insurance.

Chewing that only happens while you are out is a different problem from chewing generally, and the usual chew-swapping advice will not touch it. Our guide to separation anxiety in dogs explains how to tell the two apart using a camera and the first two minutes of footage.
