Why Dogs Chew Furniture & How to Stop It

Common Reasons Dogs Chew Furniture and Household Items

Dogs chew on household items like couches and tables for a variety of reasons. Puppies often chew because they’re teething—just like human babies, their gums itch and hurt as new teeth come in. Chewing helps relieve that discomfort through counterpressure. Even after teething ends, many dogs keep using their mouths to explore their environment, as their sense of taste and touch develops early in life. Older dogs may chew due to boredom, pent-up energy, or because they never learned what’s acceptable to chew. Some dogs chew out of habit, especially if they were never taught otherwise.

In some cases, chewing is linked to anxiety or stress, particularly when dogs are left alone. This is known as separation anxiety, and it requires specific attention. Regardless of the cause, chewing is a natural behavior—dogs have evolved to chew on bones and tough materials for survival. The challenge comes when that instinct clashes with household items.

Why Chewing Can Be Dangerous

Chewing on inappropriate items can lead to serious health risks. Dogs may fracture teeth, cut their gums, or swallow objects that cause intestinal blockages, which may require surgery. Ingesting non-food items like fabric, plastic, or paper is called pica and is a concerning behavior that needs attention. Even if the dog isn’t swallowing something dangerous, chewing on furniture, shoes, or electronics can cause expensive damage and create safety hazards. For example, chewing on electrical cords can lead to shocks or fires.

How to Prevent and Redirect Chewing Behavior

The best way to stop destructive chewing is prevention. Keep shoes, trash, and valuable items out of reach—store them in closed cabinets, behind doors, or in toy boxes with lids. If your dog is unsupervised, limit access to tempting areas. Always provide safe, appropriate chew toys like durable rubber toys, rawhides, or vet-approved alternatives. Let your dog explore different textures and types to find what they like.

When you catch your dog chewing something they shouldn’t, calmly replace it with a proper chew toy. Click and reward them when they switch to the correct item. This helps them make the connection between the right behavior and a positive outcome. Use a cue like “chew” or “toy” to reinforce the desired action. Over time, your dog will learn to choose the right item on command.

Training Tips for Puppies and Adult Dogs

Puppies are especially prone to chewing due to teething and curiosity. Instead of punishing them, guide them toward safe chew options. If your puppy starts on a shoe, redirect them to a chew toy and reward them. Consistency is key—repeat this process every time to build the habit.

For adult dogs with long-standing chewing habits, training may take longer. These dogs may need stronger deterrents, such as rubbing wintergreen oil on furniture (a natural, non-toxic scent dogs dislike). Avoid chasing your dog or grabbing the item they’re chewing, as this can feel like a game. Instead, use a firm “No” and redirect their attention.

When to Seek Help for Anxiety-Related Chewing

If your dog chews only when left alone or shows signs of panic, fear, or distress, the issue may be separation anxiety. This requires more than basic training—specialized strategies are needed. Chapter 17 of *Lucky Dog Lessons* and other resources offer guidance for managing anxiety-driven behaviors. Addressing the root emotional cause is essential for long-term success.
