The first time my dog chewed through a chair leg, I genuinely thought I could sand it smooth and nobody would notice. I was wrong. There was a two-inch chunk missing, and the chair wobbled for the rest of its life. That dog was not a monster! She was bored and teething and doing exactly what dogs do when nobody tells them otherwise. The good news is that furniture-chewing is one of the more solvable dog behavior problems. It just takes a combination of the right approach for your specific dog and some patience on your end.
Quick Answer: How to Stop Dog Chewing Furniture
The most effective way to stop a dog from chewing furniture is to combine redirection with management. Provide appropriate chew toys that satisfy the urge to chew, use a safe bitter deterrent spray on furniture surfaces, and limit unsupervised access to rooms with tempting items. For puppies, address teething specifically with cold chew toys. For anxious dogs, tackle the root anxiety rather than just the symptom. Consistency is the key variable. Most methods fail because they are applied once and then abandoned.
Why Dogs Chew Furniture (The Root Causes)
Before you can fix the problem, it helps to understand why it is happening. Dogs chew furniture for several distinct reasons, and the approach that works for one may not work for another.
Teething in puppies: Between three and six months of age, puppies experience significant discomfort as their adult teeth come in. Chewing provides relief, and unfortunately your sofa leg is just as good as anything else if nothing better is offered. This type of chewing tends to taper off once the teething phase ends, but establishing good habits during this window matters.
Boredom and excess energy: A dog that is not getting enough physical exercise or mental stimulation will find ways to occupy itself. Chewing is satisfying, engaging, and time-consuming, which makes it a natural go-to. If your dog chews mainly when you are out or inactive, boredom is a strong candidate.
Anxiety, particularly separation anxiety: This is the one that catches many owners off guard. Anxious chewing typically intensifies when the dog is left alone, and the targets are often items that smell like their owner (sofa cushions, shoes, the edge of the bed). If your dog seems distressed when you leave (pacing, whining, destructive behavior), the chewing is a symptom of something bigger.
Natural chewing instinct: Some dogs, particularly working and retriever breeds, have a strong innate drive to chew. There is nothing wrong with the dog, they simply need the behavior redirected rather than extinguished.
1. Redirect to Appropriate Chew Toys
This is the foundation of any chewing solution. The goal is not to stop your dog from chewing (that is fighting biology) but to give them something that satisfies the urge and survives the process.
The toys that hold up best are durable rubber chews like Kongs, nylon bones, and bully sticks. What I have found works better than simply handing over a toy is making the toy genuinely more appealing than the furniture. Stuff a Kong with peanut butter or kibble and freeze it overnight. The frozen version takes significantly longer to work through, which means your dog is occupied for a real stretch of time rather than three minutes.
Rotate the toys regularly. Dogs, not unlike toddlers, quickly lose interest in the same object. Keeping four or five toys in rotation and swapping two out every few days keeps things novel. A toy that reappears after a week away is practically new again.
For teething puppies specifically, chilled or frozen rubber toys provide relief alongside distraction. Dampen a thick rope toy and freeze it, or freeze a Kong stuffed with wet food. The cold helps with gum discomfort in a way a room-temperature toy cannot.
2. Use Bitter Deterrent Sprays Safely
Bitter sprays are exactly what they sound like: non-toxic sprays with an intensely unpleasant taste that makes furniture surfaces unappealing to chew. The most commonly recommended options are Grannick’s Bitter Apple and similar products from Fooey or Rocco & Roxie.
A few things to know before you start:
- Test the spray on a hidden area of the furniture first, particularly on wood or leather, to confirm it does not leave a residue or discolouration.
- Reapply every few days. The taste dissipates with time, and a dog that encounters the sprayed surface once and finds it unpleasant may return a week later once the effect has worn off.
- Some dogs are unfazed by bitter apple (I had one that appeared to find it perfectly acceptable). If your dog seems indifferent, try a different product or formulation.
Do not use hot sauce, chilli, or any homemade concoctions. These can irritate eyes and mucous membranes if a dog rubs their face after mouthing a surface, and they are genuinely unkind in a way that commercial deterrents are not.
3. Positive Reinforcement Training
Punishment-based approaches (shouting, spraying with water) do not teach a dog what to chew, they just create a dog that learns to chew when you are not watching. Positive reinforcement builds the habit you actually want.
The process is straightforward. When you catch your dog about to chew furniture or actively starting to chew it, calmly interrupt them with a firm “leave it” or “no,” then immediately offer a chew toy. The moment they engage with the toy, praise them warmly. Over time, the dog learns that the toy is the thing that earns attention and praise, while the furniture is just furniture.
Timing matters a great deal here. Praising the dog seconds after they have moved on from the furniture does not work. You need to mark and reward the correct behavior as it happens. If you come home to a chewed chair leg, do not react to it at all. The dog will not connect your frustration to something that happened three hours ago.
4. Managing the Environment (Crating, Baby Gates, and Supervision)
This one is less glamorous than training, but it is the most reliable short-term tool: if your dog cannot access the furniture, they cannot chew it. Management is not a substitute for training, but it buys you time to build good habits without ongoing damage.
Crate training, done correctly, gives a dog a calm, secure place to rest when unsupervised rather than the run of a room full of tempting objects. A well-crate-trained dog genuinely enjoys their crate. The key is to introduce it gradually and positively, never use the crate as punishment.
Baby gates and closed doors work just as well for keeping a dog out of the living room or office during the training period. This is not a forever arrangement; it is a temporary management tool while the redirection and training take hold.
Tethering your dog near you on a long lead during the initial training weeks also works surprisingly well. They can settle at your feet, but every time they start to wander toward the sofa with that look, you can redirect them before the chewing begins.
5. Address Anxiety-Related Chewing
If your dog’s chewing intensifies specifically when they are left alone, or if it is accompanied by other signs of distress like excessive barking, toileting indoors, or destruction concentrated near exits, separation anxiety may be the driver. This is worth taking seriously because addressing only the chewing while the anxiety remains unresolved is not a real solution.
Mild cases often improve with the following:
- Keeping departures and arrivals low-key, so your comings and goings are not major events that spike the dog’s arousal.
- Providing a stuffed Kong or long-lasting chew toy as you leave, so the dog’s first association with your departure is something positive.
- Increasing exercise before periods of time alone, so the dog has less anxious energy to burn.
More significant separation anxiety warrants a consultation with a veterinary behaviourist or a certified professional dog trainer. There is no shame in asking for help with this, it is a recognised condition, and it responds well to structured behaviour modification when the approach is right.
6. Increase Physical Exercise and Mental Stimulation
I have said this to friends probably a dozen times: a tired dog is a well-behaved dog. If a dog is chewing out of boredom or excess energy, no amount of bitter spray or redirection will solve the underlying problem until that energy has somewhere to go.
Most medium and large breeds need more exercise than a short walk around the block twice a day. An hour of vigorous exercise (fetch, off-lead running, a long hike) makes a noticeable difference to a dog’s resting state. On days when that is not possible, mental stimulation can partially compensate. Puzzle feeders, sniff games, and short training sessions all burn mental energy in a way that leaves a dog pleasantly tired.
If your dog is chewing mainly in the evenings or after long indoor days, the energy equation is probably the first thing to address.
7. Repairing Furniture After Dog Chewing
Once you have the chewing under control, you may be left with some cosmetic damage to deal with. Minor gnaw marks on wood furniture can often be filled with wood filler, sanded smooth, and touched up with matching stain or paint. More significant damage to chair legs, table corners, or upholstered pieces depends on the material and extent of the chewing.
If you have a pet that is still working through the transition, investing in slipcovers or furniture protectors on the most-used pieces is a sensible middle ground. If you are also dealing with dogs who like to be on your furniture, my guide to keeping your dog off the furniture entirely walks through the most effective approaches for that problem alongside boundary training.
Frequently Asked Questions
Why is my dog chewing furniture all of a sudden?
Sudden-onset chewing in an adult dog that did not chew before is usually triggered by a change in routine (new work hours, a move, a new family member), boredom, or a developing anxiety issue. If there is no obvious environmental cause, a vet check is worthwhile to rule out pain-related stress, which can also drive unusual chewing behaviour.
Does bitter apple spray actually work?
For most dogs, yes. But not universally. It works best as part of a combined approach (deterrent spray plus redirection to appropriate toys plus supervised training). On its own, a determined chewer will often just shift to an unsprayed surface.
At what age do puppies stop chewing everything?
The peak teething phase runs roughly from three to six months. Many puppies calm down significantly once their adult teeth are fully in, between six and eight months. However, if chewing has become a habit or a stress response, it can persist into adulthood without intervention.
Is it too late to train an older dog to stop chewing furniture?
No. Older dogs can absolutely learn new habits. The process may take a little longer because you are replacing an established behaviour rather than shaping a new one, but the same principles of redirection and positive reinforcement apply.
A Note on Pets and Furniture More Broadly
Dogs that chew furniture are often also dogs that jump on furniture, leave odours behind, and do other things that test your goodwill toward the species. If you are dealing with persistent dog smell even after the chewing is resolved, the techniques in my post on getting rid of dog gland smell on furniture cover the most effective deodorising approaches. If you also have cats who scratch rather than chew, the same logic of redirection and deterrents applies. I have a separate guide on home remedy approaches for stopping cats from scratching furniture if that is also relevant to your household.
The honest version of this whole topic is that living with dogs and good furniture requires some ongoing compromise and management. The chewing is solvable. The muddy paw prints, on the other hand, I have not fully cracked yet.
