How to Stop Destructive Chewing in Puppies and Dogs
By Dr Duncan Houston
Quick Answer
Destructive chewing in dogs is usually caused by teething, boredom, anxiety, or lack of structure. The solution is not to stop chewing, but to redirect it by increasing mental and physical stimulation, removing access to high-risk items, and consistently rewarding appropriate chewing behavior. If chewing is persistent or escalating, it may indicate anxiety or a medical issue and should be assessed by a veterinarian.
Why Dogs Chew
Chewing is normal. The problem is not the behavior itself. It is where that behavior is directed.
In practice, destructive chewing almost always comes down to one of a few core drivers.
Puppies
-
Teething, typically up to 6 to 8 months of age
-
Exploring the environment through the mouth
-
Lack of structure or supervision
-
Play and curiosity
Adult Dogs
-
Boredom or excess energy
-
Separation anxiety or stress
-
Lack of mental enrichment
-
Hunger or lack of foraging outlets
-
Learned behavior from lack of early training
Most owners underestimate how much stimulation their dog actually needs. What looks like “bad behavior” is often an under-stimulated brain.
What Vets Actually See Behind Destructive Chewing
This is where it matters clinically.
What starts as chewing furniture can sometimes be linked to:
-
Separation anxiety that escalates into self-injury
-
Pica, where dogs ingest non-food items
-
Gastrointestinal obstruction from swallowed objects
-
Dental pain causing abnormal chewing behavior
If your dog is not just chewing but also swallowing objects, this moves from a behavior issue to a medical risk.
The 4 Levels of Chewing: When to Worry
Level 1: Normal
-
Puppy chewing appropriate toys
-
Mild curiosity chewing
Monitor and redirect.
Level 2: Mild Problem
-
Occasional damage to household items
-
Happens when unsupervised
Increase structure and enrichment.
Level 3: Concerning
-
Repeated destruction despite intervention
-
Targeting specific objects or areas
-
Occurs during owner absence
Consider behavioral assessment.
Level 4: High Risk
-
Eating non-food items
-
Breaking teeth on hard objects
-
Signs of anxiety or distress
-
Vomiting, lethargy, or reduced appetite
This needs veterinary input.
How to Stop Destructive Chewing
These are the strategies that actually work in real households.
1. Increase Physical and Mental Stimulation
Most dogs are under-stimulated.
-
Daily exercise matched to breed and age
-
Food-based enrichment such as puzzle feeders
-
Training sessions that challenge the brain
Feeding from a bowl takes minutes. Feeding through enrichment can take 20 to 40 minutes and dramatically reduces destructive behavior.
2. Control the Environment
Prevention is not optional. It is essential.
-
Remove shoes, remotes, and loose items
-
Restrict access to high-risk areas
-
Keep the environment predictable
Dogs rehearse behaviors. Every time they successfully chew something, the habit strengthens.
3. Supervise or Contain
Freedom is earned, not given.
-
Supervise closely during free time
-
Use crates, pens, or safe rooms when unsupervised
-
Tether training can help with real-time correction
If you cannot supervise, you must control the environment.
4. Provide Appropriate Chew Outlets
Not all chew toys are equal.
-
Use durable, flexible chew toys
-
Rotate toys to maintain novelty
-
Reinforce when your dog chooses the correct item
Timing matters. Reward immediately when they chew the right thing.
5. Redirect, Do Not Punish
Punishment increases anxiety and often worsens the behavior.
Instead:
-
Interrupt calmly
-
Redirect to an appropriate chew
-
Reward heavily when they switch
This builds understanding rather than fear.
6. Use the Trade System
If your dog grabs something inappropriate:
-
Offer a higher-value item
-
Wait for voluntary release
-
Reward the decision
This prevents resource guarding and builds trust.
7. Avoid Mixed Signals
Do not give old household items as toys.
Dogs do not understand the difference between:
-
Old shoe
-
Expensive shoe
Consistency matters.
8. Watch for Early Signs of Anxiety
Chewing linked to anxiety often shows patterns:
-
Happens when you leave
-
Targets doors, windows, or barriers
-
Escalates over time
This is not a training issue alone. It requires a different approach.
9. Rule Out Medical Causes
Less common, but important:
-
Dental pain
-
Gastrointestinal issues
-
Nutritional deficiencies
-
Neurological or compulsive disorders
If the behavior is unusual, persistent, or worsening, it should be assessed.
Safe vs Risky Chew Items
Not all chew options are safe.
Safer options
-
Durable rubber toys
-
Food-dispensing toys
-
Vet-approved dental chews
Higher risk items
-
Hard bones that can fracture teeth
-
Rawhide that can cause choking or obstruction
-
Cheap plastic toys that splinter
If a chew item is harder than your dog’s teeth, it can break them.
Common Mistakes Owners Make
-
Waiting for the dog to “grow out of it”
-
Giving too much freedom too early
-
Using punishment instead of redirection
-
Not providing enough mental stimulation
-
Ignoring early warning signs of anxiety
-
Leaving high-value items within reach
These are the patterns that prolong the problem.
What To Do Right Now
If your dog is currently destructive:
-
Remove access to high-risk items immediately
-
Increase daily physical and mental stimulation
-
Introduce structured chew options
-
Supervise or contain when unsupervised
-
Track when the behavior occurs
If there is no improvement within 2 to 4 weeks, escalate to professional input.
Frequently Asked Questions
Why is my dog suddenly chewing everything?
Sudden changes are often linked to boredom, stress, or changes in routine. In some cases, it can indicate anxiety or medical discomfort.
Do dogs grow out of destructive chewing?
Some improve with age, but most do not “grow out of it” without proper structure and training.
Is chewing a sign of anxiety?
It can be. Especially if it happens when you leave, or targets doors, windows, or confined areas.
Can teething cause destructive chewing?
Yes. Puppies chew to relieve discomfort. This phase peaks between 3 to 6 months but still requires management.
Should I use bitter sprays or deterrents?
They can help in some cases, but they should never replace training, supervision, and enrichment.
How much exercise does my dog actually need?
More than most owners think. High-energy breeds may need 1 to 2 hours daily plus mental stimulation.
Why does my dog only chew when I leave?
This strongly suggests separation-related stress or anxiety.
Can chewing be dangerous?
Yes. Swallowing objects can lead to intestinal blockages, which are surgical emergencies.
What if my dog eats what they chew?
This is a high-risk situation. You need to involve a veterinarian immediately.
Are bones safe for dogs?
Some are, but many cause tooth fractures or digestive issues. Risk varies significantly.
How long does it take to fix destructive chewing?
With consistency, most cases improve within weeks. Severe anxiety-related cases take longer.
Should I crate my dog?
Crates can be very effective when used correctly and positively, especially during training phases.
What toys are best for aggressive chewers?
Durable rubber toys and food-dispensing toys tend to be the safest and most effective.
Can diet affect chewing behavior?
Yes. Hunger, poor satiety, or lack of foraging outlets can contribute.
When should I see a vet?
If the behavior is persistent, worsening, linked to anxiety, or involves eating objects.
Final Thoughts
Destructive chewing is not a personality flaw. It is a signal.
In most cases, it reflects unmet needs, lack of structure, or underlying stress. When you address the cause, not just the symptom, the behavior improves quickly.
The difference between a destructive dog and a well-behaved one is usually not intelligence. It is guidance, structure, and consistency.
