Why Do Dogs Chew Everything? Causes and Solutions

If your dog seems determined to chew everything in sight—from your shoes and furniture to electrical cords and anything else they can reach—you are definitely not alone.

Chewing is a completely normal behaviour for dogs. The problem starts when your dog doesn't understand the difference between something that's okay to chew and something that isn't.

So, why do dogs chew everything?

Dogs may chew because they're puppies going through teething, bored, curious, looking for attention, anxious, or simply because chewing is enjoyable. Understanding the reason behind the behaviour is the first step toward stopping it.

The good news is that destructive chewing can often be reduced by giving your dog appropriate alternatives, providing enough exercise and mental stimulation, and making unwanted objects harder to access.

Why Do Dogs Chew Everything?

There isn't always one single reason a dog chews. Different dogs may chew for completely different reasons.

Here are some of the most common causes.

1. Puppies Chew Because They're Teething

If you have a puppy, chewing is particularly common.

Puppies explore their environment with their mouths, and chewing can become even more noticeable while they're going through the teething stage. Your puppy may chew furniture, shoes, toys, blankets, or practically anything else within reach.

Instead of expecting a puppy to stop chewing altogether, the goal should be to teach them what they are allowed to chew.

Providing appropriate puppy-safe chew toys gives them an outlet for this natural behaviour.

When your puppy chooses an appropriate toy, praise them or otherwise reinforce the behaviour you want to see.

2. Your Dog Is Bored

A bored dog may find its own entertainment.

And unfortunately, your dog's idea of entertainment might be destroying your favourite pair of shoes.

Dogs need more than food and a place to sleep. They also need physical activity and mental stimulation.

If a dog spends most of the day with very little to do, chewing can become an easy way to occupy itself.

Interactive toys, puzzle toys, training sessions, sniffing activities, and regular play can give your dog more appropriate ways to stay occupied.

3. Your Dog Has Too Much Energy

Sometimes destructive chewing is connected to a lack of physical activity.

A dog with plenty of unused energy may look for something to do around the house. Chewing furniture or grabbing household objects can become part of that activity.

The amount of exercise a dog needs depends on factors such as age, breed, health, and individual temperament.

Instead of simply trying to stop the chewing, consider whether your dog is getting enough appropriate activity throughout the day.

Walks, play sessions, training, and age-appropriate activities can all help.

4. Chewing Can Be a Way to Explore

Dogs experience the world differently from humans.

They use their noses, eyes, ears, and mouths to investigate their surroundings. A new object on the floor can be extremely interesting to a curious dog.

This is one reason puppies in particular seem determined to investigate everything.

Rather than relying entirely on punishment after your dog picks something up, make appropriate items available and keep tempting objects out of reach.

Over time, your dog can learn which things are appropriate to chew.

5. Anxiety or Stress May Play a Role

Some dogs chew when they are stressed or anxious.

For example, a dog that becomes distressed when left alone may chew doors, furniture, or other objects while its owner is away.

Chewing does not automatically mean your dog has anxiety, but destructive behaviour that happens mainly when the dog is alone can be worth paying attention to.

Look for patterns.

Does the chewing happen when you leave the house? Does your dog also bark excessively, pace, try to escape, or show other unusual behaviours?

If destructive chewing appears connected to significant anxiety or distress, consider speaking with a veterinarian or qualified animal behaviour professional.

6. Your Dog May Have Learned That Chewing Gets Attention

Dogs learn from the reactions they receive.

If your dog grabs a shoe and everyone immediately starts chasing them around the house, your dog may learn that stealing shoes is a great way to start a game.

Instead of turning it into a chase, calmly redirect your dog toward an appropriate toy.

The goal is to make the correct behaviour more rewarding than the unwanted behaviour.

How to Stop a Dog From Chewing Everything

Once you understand why your dog is chewing, you can start working on the behaviour.

Keep Tempting Objects Out of Reach

One of the easiest ways to prevent destructive chewing is to remove opportunities for it.

Put shoes away. Keep clothing off the floor. Store household items where your dog cannot reach them.

This is particularly important with puppies because they are still learning what is appropriate.

You shouldn't have to constantly tell your dog not to chew something if you can simply remove access to it.

Give Your Dog Appropriate Chew Toys

Your dog needs something they are allowed to chew.

Choose toys designed for dogs and appropriate for your dog's size and chewing habits.

Different dogs prefer different textures, shapes, and types of toys, so you may need to try a few options to discover what your dog enjoys.

Always supervise your dog with new toys and regularly check them for damage. Replace toys that become broken or unsafe.

Redirect Instead of Punishing

Imagine your dog picks up your shoe.

You could shout, chase them around the room, and take the shoe away.

Or you could calmly exchange it for an appropriate toy and praise your dog when they start playing with the toy.

The second approach teaches your dog what you want them to do.

The goal isn't simply:

"Don't chew that."

It's:

"Chew this instead."

That distinction can make training much easier.

Use Puzzle Toys for Mental Stimulation

Chewing isn't the only way to keep a dog occupied.

Puzzle toys can encourage dogs to think, investigate, and work for rewards.

They're particularly useful for dogs that seem to get bored easily.

You can also provide mental stimulation through basic obedience training, scent games, hide-and-seek, and supervised exploration.

Mental exercise can be just as valuable as physical activity for keeping your dog engaged.

Make Your Home Dog-Friendly

If you have a dog that loves chewing, take a look around your home from your dog's perspective.

What can they reach?

Are there shoes beside the door? Electrical cables within reach? Food on low surfaces? Children's toys on the floor?

Managing the environment can prevent many problems before they happen.

This is especially important because some household objects can be dangerous if chewed or swallowed.

Keep potentially dangerous objects securely away from your dog, and seek veterinary advice promptly if you believe your dog has swallowed something potentially harmful.

What If Your Dog Chews Furniture?

Furniture can be particularly frustrating because replacing it isn't cheap.

If your dog repeatedly chews a particular chair, table, or sofa, prevent access when possible.

You can also increase supervision and redirect your dog toward an appropriate chew toy whenever they show interest in the furniture.

Most importantly, look at why the behaviour is happening.

If your dog is bored, provide more stimulation.

If they're a puppy, provide suitable chewing alternatives.

If the behaviour happens primarily when they're alone, consider whether separation-related stress could be involved.

Solving the underlying problem is usually more effective than simply trying to stop the behaviour.

How to Teach Your Dog What They Can Chew

Consistency matters.

Everyone in your household should follow the same rules.

If your dog is allowed to chew old shoes but punished for chewing new shoes, they may struggle to understand the difference.

Instead, make the rule simple:

Dog toys are for chewing. Household items are not.

When your dog chooses their toy, reinforce that choice.

When they pick up something inappropriate, calmly redirect them.

With repetition, your dog can gradually learn which objects are acceptable.

How to Prevent Chewing When You're Away

Before leaving your dog alone, make sure their environment is safe and free from tempting objects.

Give them appropriate toys or activities that they can use safely while you're away.

Some dogs may also benefit from having a predictable routine involving exercise, feeding, rest, and play.

However, if your dog consistently destroys things only when left alone, don't assume they're simply being naughty. Consider whether there could be an underlying separation-related issue and seek professional guidance if necessary.

When Should You Be Concerned About Chewing?

Occasional chewing is normal.

However, speak with your veterinarian if your dog's chewing behaviour is sudden, extreme, or accompanied by other concerning changes.

You should also seek professional advice if your dog repeatedly swallows non-food objects or if you're struggling to manage destructive behaviour despite consistent training and environmental changes.

A veterinarian can help rule out potential medical causes and determine whether additional behavioural support may be appropriate.

Frequently Asked Questions

Why do dogs chew everything?

Dogs may chew because of teething, boredom, curiosity, excess energy, attention-seeking, anxiety, or simply because chewing is a natural and enjoyable behaviour.

How do I stop my dog from chewing furniture?

Limit access to the furniture, provide appropriate chew toys, supervise your dog, and calmly redirect them whenever they begin chewing something they shouldn't.

Why does my puppy chew everything?

Puppies naturally explore their environment with their mouths, and teething can increase their desire to chew. Providing appropriate puppy-safe toys and consistent training can help.

What are the best toys for dogs that chew a lot?

Look for dog toys designed for chewing and appropriate for your dog's size and chewing style. Always supervise your dog with new toys and replace damaged ones.

Does exercise help stop destructive chewing?

Regular physical activity can help prevent boredom and give your dog an appropriate outlet for energy. Mental stimulation and training can also be important.

Should I punish my dog for chewing?

Punishment isn't usually the most effective way to teach your dog what you want them to do. Redirecting your dog toward an appropriate toy and reinforcing good choices can be more useful.

Final Thoughts

So, why do dogs chew everything?

Usually, there's a reason behind the behaviour.

Your dog may be teething, bored, curious, full of energy, seeking attention, or experiencing stress. Once you understand the reason, it becomes much easier to address the problem.

Don't focus only on stopping your dog from chewing. Give them something appropriate to chew, provide enough physical and mental stimulation, manage their environment, and consistently reinforce the behaviour you want.

With patience and consistency, your dog can learn that your furniture, shoes, and other household belongings aren't chew toys.
