By Dr. Duncan Houston BVSc

Hello—I’m Dr Duncan Houston BVSc, veterinarian and Ask A Vet founder. Destructive chewing and scratching are common but often avoidable with insight and planning. In this vet‑approved guide, learn:

🐾 Why dogs chew and scratch—normal behavior or deeper issues
🧩 How to determine the motivation: teething, boredom, anxiety, escape
🛠 Practical solutions: management, training, enrichment, deterrents

1. Why Dogs Chew & Scratch

Chewing and scratching serve many purposes:

Teething/exploration: Puppies explore with mouths and claws
Boredom or lack of enrichment: Dogs need mental and physical challenges to stay content
Anxiety or stress: Separation anxiety or barrier frustration can trigger destructive behavior
Attention seeking or habit: Learned over time when behaviors are reinforced
Medical causes: Pain, dental issues, or allergies may be the underlying trigger

2. Behavior Detective: The What, When & Where

What? Are they chewing shoes, furniture, walls, or digging in yard?
When? Only alone? While you’re home? At specific times?
Where? At doors, barriers, crates, couches, yard areas protruding to wildlife?

Mapping patterns helps you tailor solutions—whether it's anxiety-related, boredom-driven, or instinctual behavior.

3. Step‑by‑Step Solutions

3.1 Rule Out Medical Issues

A vet check is essential to rule out pain, dental disease, allergy, infection, or pica.

3.2 Dog‑Proof Your Environment

Keep valuables out of reach—shoes, cords, remote controls
Use crates or gated safe zones when you can’t supervise
Block visual triggers to reduce barrier or prey-driven behavior

3.3 Offer Enrichment & Exercise

Long walks, fetch, training sessions, treadmill activity
Mental games—food puzzles, nose work, Doggy day care
Chew toys—durable, varied types and rotated to prevent boredom

3.4 Apply Deterrents & Redirection

Use bitter-spray deterrents on off-limit items
Redirect to acceptable chew options; reward compliance
Avoid punishment—redirect instead of scolding to prevent fear

3.5 Manage Anxiety & Barrier Frustration

Use crates strategically (when not stress-causing)
Desensitize barriers; train calm behavior at crates/doors
Consider pheromone diffusers, white noise, or calming wraps

3.6 Consistency & Supervision

Supervise closely and use baby gates or crates until safe behavior becomes habit.

4. How Ask A Vet,

Ask A Vet App: Share behavior videos and get expert guidance on stress, training tips, and rule-out medical issues.

5. When to Seek Professional Help

Persistent chewing or escalation (destruction of doors, walls)
Aggressive guarding of items or reactivity when redirected
Signs of severe anxiety—pacing, drooling, vocalizing, and self-trauma
No improvement after consistent management and enrichment
Consider a veterinary behaviorist or certified trainer

📌 Final Thoughts from a Vet

Destructive chewing and scratching are rarely rebellion—they signal your dog’s needs: attention, stimulation, comfort, or relief from stress. By observing carefully, vet-checking, enriching their life, and using management tools, you can redirect behaviors into positive outlets.
