I've walked into houses where the furniture was shredded, the baseboards were chewed to splinters, and the owner had given up on having nice things. In almost every case, the dog wasn't destructive out of spite or malice. They were destructive because something wasn't being addressed.
Destructive behavior is a symptom. The fix depends on the cause.
Why Dogs Chew
Teething. Puppies between 3-6 months are uncomfortable, and chewing provides relief. This is normal, predictable, and temporary. The response is management (remove access to what you don't want chewed, provide appropriate chews) and patience.
Natural drive. Many dogs have strong oral drives — labs, goldens, terriers, herding breeds. These dogs need to chew the way other dogs need to run. Denying the behavior without providing an appropriate outlet produces increasingly creative destruction.
Under-stimulation. A bored dog with unspent energy will find things to do. Chewing, digging, and destruction are all ways of creating self-stimulation when the environment doesn't provide enough. This is the most common cause in otherwise healthy adult dogs.
Separation anxiety. Dogs with genuine anxiety about being alone often focus their distress on exit points — doors, windows, sometimes the owner's belongings that carry their scent. This type of destruction is specific, concentrated, and usually accompanied by other anxiety symptoms.
Why Dogs Dig
Digging has a different set of drivers:
Natural drive. Terriers were literally bred to dig. Nordic breeds dig to create cool resting spots. This is instinct, and attempts to eliminate it entirely are swimming upstream.
Temperature regulation. Dogs digging to create a cool hole or a sheltered depression are meeting a comfort need. Providing shade and cool resting spots addresses the need directly.
Scent of prey. Dogs that smell rodents, grubs, or other animals under the soil will dig to investigate. This can be motivated by the prey drive and is particularly strong in terriers and some sporting breeds.
Boredom. Same as chewing — an under-stimulated dog with high energy turns to environmental manipulation.
The Universal First Response: Management
Whatever the cause, management stops the damage while you address the root cause.
For chewing: puppy-proof the environment. Remove access to items you don't want destroyed. Crate or pen the dog when unsupervised. Provide rotating, high-quality chews and monitor the dog's preference — some dogs prefer harder chews, others prefer softer ones.
For digging: supervise outdoor time. Don't leave the dog unsupervised in the yard with nice landscaping. Consider a dedicated "dig zone" — a specific area where digging is permitted and encouraged.
Addressing Root Causes
Increase exercise and mental stimulation for under-stimulated dogs. A dog who's had a forty-five minute off-leash run and a ten-minute training session doesn't have the same energy surplus as a dog who got a ten-minute leash walk.
Provide appropriate outlets. A dog that needs to chew should have access to appropriate chews at all times. A dog that needs to dig should have somewhere to do it. Managing the natural behavior toward appropriate outlets is more sustainable than suppression.
Address anxiety appropriately. Separation-related destruction needs a separation anxiety protocol, not just chew toys. See a trainer or veterinary behaviorist for significant cases.
For puppies: patience and management. Teething ends. The destruction that started at 12 weeks is usually dramatically reduced by 8 months with consistent management and appropriate chew provision.
FAQ
My dog only destroys things when I'm not home. Is that separation anxiety?
Not necessarily — it might also be boredom, opportunity, or habit. Check for other anxiety symptoms (the camera diagnostic from the separation anxiety article applies here too). Does the destruction start quickly after you leave? Is it focused on exit points? Does the dog show distress signals before or during departure? If yes to these, lean toward anxiety. If the destruction happens after a long period alone and is more diffuse, lean toward boredom/opportunity.
My adult dog just started chewing things suddenly. What changed?
Sudden onset destructive behavior in an adult dog that previously didn't have this problem warrants investigation. Common causes: a change in schedule that's left the dog alone more, a new stressor in the environment, adolescence (if the dog is between 6-18 months), or occasionally a medical issue causing increased anxiety or oral sensitivity.
Is it ever okay to let a dog chew furniture?
No, because allowing access to the furniture undermines the "not this, but this instead" message you're trying to send. The dog can't distinguish between "the corner of this couch is okay but the couch overall is not." Redirect consistently to appropriate items.
What are the best chews for heavy chewers?
This is individual to the dog. What works well: bully sticks, raw bones appropriate to the dog's size, rubber chew toys with food stuffed inside, deer antlers for very hard chewers. Rotate through different options to find what your dog values most. Avoid anything that requires a lot of force or has caused dental fractures — very hard items (like cow hooves in some cases) can break teeth. When in doubt, the "thumbnail test" is useful: if you can press your thumbnail into the surface, it's generally safe for chewing.
The most important thing: every dog that's destroying things is trying to meet a need. Figure out the need, redirect appropriately, and the behavior changes.
