Dog Chewing: Why Dogs Chew & How to Stop Destructive Chewing (2026)

Chewing is a completely natural dog behavior — but when it’s directed at your shoes, furniture, or baseboards, it becomes a serious problem. The good news is that destructive chewing is almost always addressable with the right approach.

This guide is for informational purposes. Consult a professional trainer or veterinary behaviorist for severe or compulsive chewing cases.

Why Dogs Chew

Chewing is not a behavioral problem in itself — it’s a fundamental canine behavior serving several purposes:

• Teething relief: Puppies between 3-6 months old experience significant gum discomfort as adult teeth push through. Chewing provides relief. See our detailed guide on puppy teething.
• Jaw strength and dental health: Chewing on appropriate surfaces keeps jaw muscles strong and helps clean teeth. See dog dental treats for vet-recommended options.
• Mental stimulation: Chewing is cognitively engaging — it occupies a dog’s mind in a way that passive rest cannot.
• Stress relief: Just as humans fidget or stress-eat, dogs chew to self-soothe during anxiety, boredom, or frustration.
• Exploration: Dogs, especially puppies, explore their world through their mouths.

Causes of Destructive Chewing

Boredom and Under-Stimulation

The #1 cause of destructive chewing in adult dogs. Dogs need both physical exercise and mental stimulation. A dog that isn’t getting enough of either will find ways to entertain themselves — your furniture is one option. High-energy breeds (Border Collies, Huskies, Vizslas, Jack Russell Terriers) need significantly more mental and physical engagement than calmer breeds.

Separation Anxiety

Dogs with separation anxiety often chew destructively when left alone. Classic signs: chewing focused on exit points (doors, windows), chewing owner’s worn clothing (which smells of the absent person), combined with other anxious behaviors like howling, pacing, and inappropriate elimination.

Puppy Teething (Normal Phase)

Expected in dogs 3-6 months old. The goal is not to stop teething chewing but to redirect it to appropriate surfaces consistently. This phase resolves on its own — most puppies reduce random chewing significantly by 18 months once adult teeth are in and basic training is established.

Attention-Seeking

Dogs quickly learn that chewing something forbidden gets an immediate, strong reaction. Even negative attention (shouting, chasing) is rewarding to some dogs. If this pattern develops, ignoring the behavior entirely and redirecting calmly is more effective than reactive punishment.

Nutritional Deficiencies

In rare cases, pica (compulsive eating of non-food objects) and excessive chewing can stem from nutritional deficiencies. If your dog chews or eats unusual things (dirt, rocks, fabric), consult your vet to rule out dietary causes.

How to Stop Destructive Chewing

Step 1: Manage the Environment

Until chewing is under control, prevent access to tempting items. Use baby gates, closed doors, and crates when unsupervised. Crate training is one of the most effective tools for protecting your home and your dog simultaneously — see our guide on crate training.

Step 2: Increase Exercise and Mental Stimulation

A tired dog is a well-behaved dog. For most medium to large breeds, this means at least 45-60 minutes of vigorous exercise daily plus training sessions and puzzle feeders. Consider dog daycare if you’re away for long periods — it provides both socialization and activity.

Step 3: Provide Appropriate Chew Outlets

Always have safe, appropriate chew toys available. Rotate toys to maintain novelty. Freeze treats inside Kongs to extend engagement. Appropriate chewing satisfies the drive; absence of appropriate options redirects it to your belongings.

Step 4: Use Taste Deterrents

Bitter apple spray and similar taste deterrents applied to furniture and cables can reduce appeal. Most dogs dislike the taste and will stop chewing treated objects. Reapply regularly and always combine with providing an appropriate alternative.

Step 5: Redirect, Don’t Punish

When you catch your dog chewing something inappropriate, say a calm “no,” take the item away, and immediately redirect to an appropriate chew toy. If they engage with the toy, praise warmly. Punishment after the fact (even seconds later) is ineffective — dogs don’t connect the punishment to the act once the moment has passed.

Choosing Appropriate Chew Toys

• Kongs and stuffed rubber toys: Durable, safe for most dogs, can be stuffed with food for extended engagement
• Bully sticks and raw hides: Natural chews that dogs typically love. Monitor during chewing; remove when reduced to a piece that could be swallowed
• Dental chews: Double as plaque reducers — see our guide on dog dental treats
• Antlers and hard bones: Long-lasting but can crack teeth. Avoid weight-bearing bones from large animals (“recreational bones”) which are too hard for most dogs
• Avoid: Shoes, socks, or similar items as toys — this teaches dogs that footwear is fair game

When Chewing Signals a Medical Issue

See your vet if chewing is accompanied by:

• Pica — eating non-food items (rocks, plastic, fabric, wood)
• Sudden onset chewing in a previously well-behaved adult dog
• Chewing at own body parts (paws, tail, flanks) — may indicate allergies, pain, or OCD
• Signs of oral pain — dropping food, excessive drooling, pawing at mouth
