Why Does My Dog Keep Putting Things in Its Mouth?

Why Dogs Chew on Things Like Socks and Toys

Dogs explore the world through their mouths—this is natural and instinctual. Puppies, born blind and deaf, rely on taste and touch to learn about their environment. Chewing helps relieve teething pain, just as it does for human babies. Older dogs may chew due to boredom, anxiety, or pent-up energy. Some dogs chew because they’ve never been taught what’s appropriate to chew on. In rare cases, chewing can be linked to nutritional deficiencies or tooth problems.

The behavior isn’t always about hunger. Dogs may chew socks, shoes, or even coins not because they’re hungry, but because they’re curious, seeking attention, or trying to relieve stress. In one case, a Great Dane in Portland, Oregon, had 43½ socks removed during emergency surgery—proof that this behavior can be dangerous if unchecked.

Common Triggers for Chewing Behavior

Boredom, anxiety, and lack of stimulation are top reasons dogs chew on inappropriate items. Without enough mental or physical activity, dogs turn to chewing as a way to pass time. Some dogs chew to get attention—even negative attention is attention. Others may chew because they’re stressed or scared, especially during loud noises or changes in routine.

Teething is a major factor in puppies. As their adult teeth grow in, chewing helps ease the discomfort. This instinct comes from thousands of years of survival—dogs once had to chew through bone and marrow to eat. Even today, many dogs still have this natural urge to chew.

How to Stop Dangerous Chewing Safely

The key to stopping destructive chewing is supervision and management, not punishment. Never leave your dog unattended with small toys or chew items that can be swallowed. If a chew toy breaks or becomes too small, it can cause intestinal blockages or tooth damage. Always supervise play and remove any item that’s been torn apart.

Instead of banning chewing entirely, teach your dog what’s acceptable. Provide a variety of safe, durable chew toys—like rubber bones, antlers, or food puzzles. Rotate toys every few days to keep them interesting. Dogs, like children, get bored with the same toys over time.

Training Your Dog to Choose the Right Chew

Use positive reinforcement to teach your dog what to chew. When you catch your dog chewing something inappropriate, calmly replace it with a proper chew toy. Click and reward them when they show interest in the right toy. Over time, they’ll learn to associate the correct behavior with a treat.

You can also add a cue like “chew” or “toy” to help your dog understand what’s expected. Practice by placing tempting items (like a shoe) next to a toy. Use your cue and reward only when they choose the toy. This builds a clear mental connection between the command and the desired behavior.

Avoid Mistakes That Make Chewing Worse

Never give your dog old shoes or socks as toys—even if you no longer wear them. Many dogs can’t tell the difference between a “safe” item and your personal belongings. If they chew one, they may assume all shoes are fair game. This can lead to more chewing and even ingestion of dangerous materials.

Also, avoid leaving valuable items like shoes or trash out in the open. Use closed doors, toy boxes with lids, or locked cabinets. Make sure your dog has plenty of appealing, safe alternatives. If your dog prefers food-based toys, try interactive ones like Kongs or Busy Buddy toys that require effort to get treats out.
