Why Is My Dog Chewing Everything?
You come home to find another destroyed couch cushion. Or your favorite shoes. Or the TV remote. Again. Dog chewing is one of the most frustrating behavior problems — and one of the most common reasons dogs are surrendered to shelters.
But here’s what most dog owners don’t understand: chewing is completely normal and natural dog behavior. Dogs explore the world with their mouths, relieve boredom and anxiety through chewing, and teethe through chewing as puppies. The problem isn’t chewing itself — it’s that they’re chewing the WRONG things.
Why Dogs Chew Destructively: The 5 Main Causes
1. Puppy Teething
Puppies between 3-6 months old are teething — their baby teeth are falling out and adult teeth are coming in. Chewing relieves the discomfort. This phase will naturally pass, but you need to provide appropriate outlets and protect your belongings in the meantime.
2. Boredom and Under-Stimulation
This is the #1 cause of destructive chewing in adult dogs. A dog left alone all day with nothing to do will find SOMETHING to do. Chewing is self-rewarding — it releases endorphins and relieves stress. If your dog is chronically bored, destructive chewing is the predictable result.
3. Separation Anxiety
Dogs with separation anxiety often chew destructively when left alone as a coping mechanism for extreme stress. You’ll notice the chewing is concentrated near exit points (doors, windows) and is accompanied by other anxiety signs like soiling, vocalization, and pacing.
4. Lack of Appropriate Chew Outlets
If your dog doesn’t have access to appropriate chewing objects, they’ll find their own. You can’t stop the chewing drive — you can only redirect it.
5. Attention-Seeking
Some dogs learn that chewing the furniture gets them immediate attention. Even negative attention (shouting, chasing) is rewarding if your dog is desperate for interaction.
8 Proven Strategies to Stop Destructive Chewing
Strategy 1: Dog-Proof Your Space
While you’re training, you need to manage the environment to prevent rehearsal of the behavior. When you can’t directly supervise your dog: confine them to a dog-proofed space, use a crate, or keep them in an area with only safe, appropriate chew items available.
Strategy 2: Provide Abundant Appropriate Chew Outlets
Your dog NEEDS to chew. Provide a rotating variety of appropriate chew items: Kongs stuffed with frozen peanut butter, bully sticks, Nylabones, deer antlers, and safe raw marrow bones. Rotate items to keep them interesting — novelty is motivating.
Strategy 3: Use Bitter Apple Spray
Apply bitter apple or bitter cherry spray to items you can’t remove from reach. The unpleasant taste deters chewing. Reapply daily for best results. Note: this manages the symptom but doesn’t address the root cause.
Strategy 4: Redirect, Don’t Just Punish
When you catch your dog chewing something inappropriate, calmly say “No” and immediately redirect to an appropriate chew toy. When they chew the appropriate item, reward with praise and treats. Punishment alone is ineffective and damages your relationship.
Strategy 5: Dramatically Increase Exercise
A physically exhausted dog doesn’t have the energy for destructive behavior. If you’re dealing with a high-energy breed, ensure they’re getting adequate physical exercise before you leave them alone. Two walks a day may not be enough for high-drive breeds.
Strategy 6: Mental Stimulation Through Brain Training
This is often more effective than physical exercise alone. Mental activity tires dogs out faster and more completely. Puzzle feeders, sniff mats, training sessions, and structured brain training games give your dog a productive outlet for their mental energy — dramatically reducing the destructive behavior that stems from boredom.
Strategy 7: Teach “Leave It” and “Off”
A solid “Leave It” command gives you an off-switch for chewing in the moment. Train this command until it’s bomb-proof by practicing with progressively more tempting items.
Strategy 8: Address Separation Anxiety
If chewing is concentrated when you’re away and accompanied by other anxiety symptoms, you’re dealing with separation anxiety. This requires a specific desensitization protocol to the triggers of your departure — not just “exercise more” or “get more toys.”
The #1 Solution: Address Boredom with Brain Training
For the majority of dogs, destructive chewing is a boredom and under-stimulation problem. The most effective long-term solution is giving your dog an appropriate outlet for their mental energy.
The Brain Training For Dogs program includes specific exercises designed to deeply satisfy your dog’s need for mental stimulation — making destructive chewing dramatically less appealing because they’re getting their cognitive needs met through appropriate channels.
Frequently Asked Questions
At what age do dogs stop chewing everything?
Puppy teething-related chewing typically eases by 6-7 months. However, adult dogs can remain destructive chewers indefinitely if the underlying issue (boredom, anxiety) isn’t addressed. Training and enrichment are more important than waiting for them to “grow out of it.”
What can I spray on furniture to stop dogs from chewing?
Bitter apple spray is most commonly used and effective for most dogs. Some dogs are undeterred by any spray — for these dogs, physical management and addressing the root cause are more effective approaches.
Should I punish my dog for chewing?
Only if you catch them in the act — after the fact, your dog won’t connect punishment to the chewing. Even then, redirection to an appropriate chew item is more effective than punishment alone.
