You come home to a chewed cushion, a raided bin or scratched paintwork — and the guilty look that follows. Before you label your dog ‘naughty’, ask a better question: why did it happen? Destructive behaviour when a dog is left alone almost always comes from one of two places — boredom or separation anxiety — and telling them apart is the key to fixing it for good.
Boredom: too much energy, nothing to do
A bored dog destroys things because it’s the most interesting option available. The clues are in the timing and the target: chewing spread across the day, focused on things that are fun to shred (cushions, shoes, cardboard), and a dog that settles happily once you offer something better. Under-exercised, under-stimulated and young dogs are the usual candidates.
Separation anxiety: panic, not mischief
Anxiety-driven behaviour feels different. It tends to start within minutes of you leaving, centres on exits (doors, windowsills, crates), and comes with other signs of distress — pacing, drooling, howling, toileting indoors, or a dog that shadows you and can’t settle when you’re out of sight. This isn’t disobedience; it’s genuine stress, and it needs a gentler, structured approach.
How to tell which one you have
- Film it. A ten-minute phone video after you leave tells you more than guesswork.
- Check the timing. Damage in the first 15 minutes leans anxiety; damage spread over hours leans boredom.
- Watch the recovery. A bored dog perks up the moment you offer a job; an anxious dog struggles to switch off even when you’re home.
What actually helps
For boredom, the answer is enrichment — a legal outlet for that busy brain. A snuffle mat turns breakfast into a ten-minute foraging game, and rotating a few puzzle and chew toys keeps novelty high. Aim to tire the mind, not just the legs.
For anxiety, build calm gradually: short, undramatic departures, a predictable routine, and a cosy retreat your dog links with good things. A calming donut bed in a quiet corner, paired with a long-lasting lick or chew as you leave, gives your dog somewhere safe to land.
If the signs point to true separation anxiety, or the behaviour is escalating, please speak to your vet or a qualified behaviourist. This guide helps you understand your dog — it isn’t a substitute for professional advice for a distressed pet.
The takeaway: most ‘bad behaviour’ is an unmet need in disguise. Work out whether it’s boredom or anxiety, meet the need behind it, and the chewing usually takes care of itself.
