Why Is My Dog Chewing Everything?

Why Do Dogs Chew So Much?

Dogs chew for many reasons, especially during puppyhood. Puppies chew because their teeth are coming in—just like human babies—and gnawing helps relieve the pain and itching in their gums. This teething phase typically lasts about six months. Even after their adult teeth grow in, many dogs continue to chew because it’s a natural way to explore their world. Since dogs are born blind and deaf, their mouth is their first sense to develop, making chewing a key way to learn about objects.

Older dogs may chew due to boredom, anxiety, or because chewing has become a comforting habit. Some dogs chew simply because they enjoy it. In some cases, chewing can be a sign of separation anxiety or fear. If your dog chews when left alone or seems overly stressed, it may point to deeper emotional needs that require attention.

Common Triggers for Chewing

Chewing is often triggered by a lack of stimulation or a need for relief. Dogs may chew on shoes, furniture, remote controls, or even socks and underwear—items that are often within reach and have strong smells. This behavior isn’t always about destruction; sometimes it’s a way to get attention, even negative attention. If your dog learns that chewing leads to a reaction from you, it can reinforce the behavior.

In some cases, chewing becomes dangerous. Dogs can swallow non-edible items like rocks, books, or hairbands, leading to intestinal blockages or tooth damage. In severe cases, surgery may be needed. That’s why it’s important to act early and manage your dog’s environment.

How to Stop Problem Chewing

The key to stopping destructive chewing is not to stop chewing altogether—but to redirect it. Dogs need to chew, so instead of trying to eliminate the behavior, teach them what’s acceptable to chew on. Provide a variety of safe, durable toys with different textures—like rubber toys, antlers, or rawhides—so your dog can find what they like.

When you catch your dog chewing something they shouldn’t, calmly replace it with a proper chew toy. As soon as they show interest in the right toy, click (if using a clicker) and reward with a treat. Repeat this consistently so your dog learns the connection between the correct choice and the reward.

Training Tips for Success

Start by preventing access to forbidden items. Put shoes in closed cabinets, use toy boxes with lids, and secure trash bins. Supervision is critical—your dog can’t chew your couch if you’re watching them. If you can’t supervise, use a crate or dog-proofed space.

Use a cue word like “chew” or “toy” to signal what they’re allowed to chew. Practice by placing tempting items (like a shoe) near a chew toy and asking your dog to choose the right one. Click and reward when they pick the toy. Over time, this builds a strong habit.

For dogs with deep-rooted habits or anxiety-related chewing, basic obedience training is essential. Skills like “leave it,” “sit,” and “look at me” help redirect attention and build self-control. A strong foundation makes it easier to manage chewing issues.

When to Seek Help

If your dog chews only when left alone, it may be a sign of separation anxiety. Chapter 17 of *Lucky Dog Lessons* offers specific strategies for this issue. If your dog is chewing dangerous items or seems distressed, consult your vet to rule out medical causes. In all cases, consistent training and environmental management are your best tools.
