Why Dogs Chew on Random Objects

Teething Causes Chewing in Puppies

Puppies chew because their teeth are coming in, which causes discomfort and itching. This process is similar to human babies teething. Chewing helps relieve the pain by applying counterpressure to sore gums. This stage typically lasts about six months until all adult teeth are in place. During this time, puppies may chew on anything they can find—soft toys, slippers, furniture legs, or even household items.

It’s unrealistic to expect a teething puppy to understand what’s safe to chew. Instead of punishing them, provide a variety of safe, durable chew toys with different textures. This helps satisfy their natural urge while protecting your belongings.

Boredom and Anxiety Drive Chewing in Older Dogs

Older dogs may chew due to boredom, anxiety, or excess energy. If they’re not mentally or physically stimulated, they may resort to chewing as a way to occupy themselves. Some dogs chew out of habit—especially if they were never taught as puppies what they should chew on.

Anxiety can also trigger chewing. Dogs may chew when left alone or in stressful situations. Even negative attention—like being scolded—can reinforce the behavior because the dog still gets interaction. This makes it important to address the root cause, not just the symptom.

Instinct and Exploration Shape Chewing Behavior

Dogs use their mouths to explore the world, especially when they’re young. Born blind and deaf, their sense of taste and touch in the mouth is one of the first developed. This makes chewing a natural way to investigate new objects.

This instinct is also rooted in survival. Thousands of years ago, dogs needed to chew through bone and marrow to survive. Many dogs still have this innate desire to chew, even in modern homes. That’s why they may chew on furniture, shoes, or even inedible items like rocks or books.

How to Stop Unwanted Chewing with Training

The key to stopping destructive chewing is not punishment—but redirection. Supervise your dog closely and prevent access to forbidden items when you can’t watch. Store shoes, trash, and valuables out of reach or in locked cabinets.

When you catch your dog chewing something inappropriate, calmly replace it with a safe, approved chew toy. Click and reward them when they switch to the correct item. This teaches them what’s acceptable through positive reinforcement.

Use a cue like “chew” or “toy” to help them associate the behavior with the right object. Practice with tempting items nearby to build their self-control. Consistency and timing are crucial for success.

Why Basic Training Is Essential for Chewing Control

Effective chewing control relies on foundational obedience skills. Commands like “sit,” “leave it,” and “look at me” help redirect your dog’s attention from forbidden items to you.

A dog with strong basic training can be guided away from temptation more easily. For example, if your dog starts chewing a couch, a simple “leave it” command can stop the behavior. This is why training isn’t just about one issue—it’s about building a strong foundation that makes solving other problems easier.
