How to Stop Your Dog from Grinding Teeth

Why Dogs Chew (Not Grind) Their Teeth

Dogs don’t typically “grind” their teeth like humans. What you may be observing is destructive chewing—gnawing on shoes, furniture, or other household items. This behavior stems from natural instincts: puppies chew during teething, while older dogs may chew due to boredom, anxiety, or simply because they explore the world with their mouths. As Dr. Herron notes, dogs use their mouths to investigate, and chewing is an ancient survival instinct from when they needed to break down bones and marrow.

Chewing isn’t caused by a lack of dental cleaning or the need to “clean” teeth. The idea that chewing helps clean teeth is a myth—dogs don’t floss or brush, and their back teeth remain uncleaned without human help. The only way to truly clean a dog’s teeth is with a toothbrush or finger brushing, not chewing.

Common Causes of Destructive Chewing

Chewing can be driven by several factors: boredom, pent-up energy, anxiety, or even a habit formed over time. Adult dogs may chew because it feels good or because they’ve never been taught what’s acceptable to chew. Some dogs chew when left alone, which may signal separation anxiety—a complex issue that requires specific strategies beyond basic training.

Puppies are especially prone to chewing due to teething, though the discomfort is usually mild and not severe. The key is not to stop chewing entirely—dogs need to chew—but to teach them what’s appropriate. If your dog is chewing dangerous or valuable items, it’s essential to intervene early and redirect the behavior.

How to Redirect Chewing Behavior

The most effective approach is redirection, not punishment. When you catch your dog chewing something forbidden, calmly replace it with a safe, approved chew toy. Use a clicker and treats to reinforce the correct choice—click and reward when your dog starts chewing the right item. Over time, this builds a strong association between the toy and positive reinforcement.

Consistency is critical. Repeat the process every time your dog reaches for something off-limits. You can also teach a cue like “chew” or “toy” to help your dog understand what’s expected. Gradually introduce tempting items (like shoes) alongside safe toys and reward only the correct choice.

Prevention and Environmental Management

Prevention is key. Dog-proof your home by keeping shoes, trash, and valuables out of reach—behind closed doors or in cabinets. Use toy boxes with lids and lockable trash bins. Supervise your dog closely, especially when they’re unsupervised. If you can’t watch them, confine them to a safe space with appropriate chew toys.

Even older dogs can learn new habits. The longer a dog has chewed, the harder it may be to change—but with patience, consistency, and proper tools, it’s possible at any age. For severe cases, consider using deterrents or consulting a professional trainer.

When to Seek Professional Help

If chewing is linked to separation anxiety, it may require targeted strategies beyond basic training. Chapter 17 of *Lucky Dog Lessons* addresses this issue in depth. If your dog is chewing dangerous items—like electrical cords or toxic substances—consult your vet immediately. In some cases, a vet may recommend behavioral evaluation or treatment.
