Why Dogs Chew Excessively & How to Stop It

Why Dogs Chew Excessively

Dogs chew for a variety of reasons, many rooted in natural instincts and developmental stages. Puppies chew primarily because they’re teething—just like human babies, their gums itch and hurt as adult teeth come in. Chewing provides counterpressure that helps relieve this discomfort. Even after teething ends, many dogs continue to chew out of habit or because they’re exploring their environment with their mouths, a behavior that begins early in life when they’re born blind and deaf.

Older dogs may chew due to boredom, anxiety, or unmet energy needs. Dogs with high energy levels often chew to occupy themselves when not given enough mental or physical stimulation. Some dogs also chew for attention—even negative attention is attention, which can reinforce the behavior. In some cases, chewing is linked to separation anxiety or fear during storms, especially if the dog is left alone for long periods.

Common Triggers & Hidden Risks

Chewing can become destructive when dogs target household items like shoes, furniture, cords, or plants. This isn’t just frustrating—it’s dangerous. Chewing on inedible or toxic items can lead to broken teeth, gum injuries, or intestinal blockages that may require surgery. Electrical cords, cleaning supplies, and medications are especially risky if left within reach.

Dogs adopted from shelters or those new to indoor living may chew more because they’re unfamiliar with household items. Without proper training, they may see furniture, shoes, or remote controls as fair game. The longer a dog continues chewing without correction, the harder it becomes to stop—especially if the behavior has become a deeply ingrained habit.

How to Stop Excessive Chewing

The key to stopping excessive chewing is prevention and redirection. First, pet-proof your home by securing trash cans, hiding cords, locking cabinets with cleaning products, and keeping shoes and valuables out of reach. Supervision is critical—dogs can’t chew your couch if you’re watching them.

Instead of punishing chewing, teach your dog what’s acceptable. Provide a variety of safe, durable chew toys with different textures—rubber toys, rawhides, antlers, or bones. Let your dog experiment to find what they prefer. When you catch them chewing something inappropriate, calmly replace it with a proper toy and reward them with a treat when they switch.

Use a consistent cue like “chew” or “toy” to help your dog make the connection between the correct behavior and the reward. Over time, this positive reinforcement helps them learn to choose safe items on their own.

Training Tips for Long-Term Success

Consistency is essential. Practice the toy replacement method multiple times until your dog reliably chooses the right item. Gradually introduce tempting objects (like a shoe or pillow) near the correct toy and use your cue to guide the choice. Click and treat when they pick the right one.

For dogs with severe habits or anxiety-related chewing, consider additional strategies like deterrent sprays or consulting a professional. If anxiety is suspected—especially during separation or loud storms—addressing the root cause is crucial. Chapter 17 of *Lucky Dog Lessons* offers specific guidance for separation anxiety.

Remember: You’re not trying to stop chewing entirely—dogs naturally chew. Instead, you’re teaching them what is safe and acceptable to chew.

Final Thoughts: Patience & Prevention Win

No dog is born knowing what not to chew. It’s up to you to guide them. Whether your dog is a teething puppy or an older dog with bad habits, the solution lies in supervision, safe alternatives, and consistent training. With patience and the right tools, you can redirect chewing behavior and protect both your belongings and your dog’s health.
