Why does my dog destroy things when left alone?

By Dr. Ruben Castro

You come home to find shredded pillows, chewed shoes, or damaged furniture. If your dog turns into a wrecking crew when left alone, you’re not alone. Destructive behavior is common among dogs. The good news is that your dog isn’t being vengeful; the reasons behind the chaos are more emotional.

It’s Not Spite, It’s Stress

Dogs are social animals that need companionship and routine. Unlike cats, dogs can develop separation anxiety when left alone for long periods or without a consistent daily routine. This often leads to unwanted behaviors, such as chewing or digging, as they cope with stress, resulting in damage to furniture and belongings.

Boredom Is a Real Issue

Boredom is another common culprit for destructive behavior in dogs. When left at home without stimulation or interaction, they may resort to entertaining themselves, which can often cause damage. High-energy breeds, such as Border Collies and Labrador Retrievers, are especially prone to this if their mental and physical needs aren’t met.

Pent-Up Energy Has to Go Somewhere

Even dogs that aren’t anxious or bored may still need a healthy outlet for their energy. Dogs are natural explorers. If they don’t get enough walks, playtime, or training, that energy builds up. Chewing, tearing, or digging becomes an outlet for pent-up emotions. And for puppies or young dogs, who are still learning what’s okay to chew, anything left within reach is fair game.

The Scent Factor

Here’s something many owners overlook: your dog is drawn to your scent. Laundry, shoes, and bedding are full of your smell, which can be comforting or confusing. Some dogs will cuddle with your worn shirt, while others might chew it up out of stress or curiosity. If your dog tends to target personal items, it may be their way of feeling closer to you when you’re away.

What Can You Do?

The good news is that destructive behavior can be managed, and often, completely prevented. Here are a few simple steps:

A. Exercise Before You Leave: A tired dog is a calm dog. A brisk walk or play session before you leave can help reduce anxiety and restlessness.

B. Create a Safe Space: Crate training or setting up a dog-proofed room with toys and water can give your pup a secure environment while you’re gone.

C. Provide Enrichment: Puzzle toys, treat-dispensing balls, or frozen Kongs can keep your dog busy and distracted in your absence.

D. Practice Departures: Desensitize your dog to your comings and goings. Short trips away, followed by calm returns, can help reduce separation anxiety over time.

E. Consider a Pet Sitter or Doggy Daycare: If your schedule keeps you out for long hours, hiring help or enrolling your pup in daycare can be a great way to prevent loneliness and boredom.

Final Thoughts

Your dog’s destructive behavior is a sign of struggle, not personal defiance. With patience, training, and creativity, you can help them feel secure and less inclined to tear things apart. They need understanding, not punishment.
