How to Stop a Border Collie Chewing Everything (Step-by-Step)

The most common advice you'll find online — and probably hear from well-meaning people at the dog park — is to give your Border Collie more exercise. Run them longer. Add a second walk. Tire them out and they'll stop destroying your couch cushions.

It sounds logical. It's also largely wrong, and for some dogs it actively makes things worse.

Border Collie destructive chewing is rarely a fitness problem. It's a mental state problem. Collies are bred to work closely with a human, problem-solve constantly, and receive rapid, clear feedback. When that need goes unmet, the arousal system stays switched on, and a wound-up collie that's just come back from a 5 km run is often more destructive — not less — because the exercise has raised their baseline arousal without giving their brain anything to do.

Here's what's actually going on, and what to do instead.

"He's doing it out of spite"

He isn't. Dogs don't chew your favourite boots because they're annoyed you left the house. They chew because the physical act of chewing is genuinely self-soothing — it releases endorphins and lowers cortisol. When a collie is under-stimulated, anxious, or simply alone with nothing to do, chewing is the rational choice from their perspective. It feels good and it works.

Believing it's spite leads owners to punish after the fact, which the dog genuinely cannot connect to the earlier chewing. All you're training is a dog who looks worried when you come home — not a dog who chews less. Any guilt or "I know what I did" face you see is appeasement behaviour triggered by your body language, not a confession.

Reality: chewing is a coping mechanism. Your job isn't to stop the coping — it's to give your dog better tools.

"Saying 'no' firmly enough will fix it"

Verbal corrections interrupt the behaviour in the moment, but collies are problem-solvers. They quickly learn "chew the chair when the human is watching = bad, chew the chair when alone = fine." You haven't changed the motivation; you've just added a scheduling constraint.

Worse, repeated corrections with no alternative offered can tip a collie into frustrated arousal — which, again, increases chewing.

Reality: management stops the damage; teaching stops the habit. Both matter, and they work in sequence.

Start with management this week:

• Tether your dog to you on a house lead when you can't actively supervise — this isn't punishment, it's information-gathering (you learn what triggers the chewing)
• Use a crate or puppy-proofed room when you leave, with a pre-approved chew item waiting
• Remove access to problem items entirely for now; you can't train a dog who's already mid-session on a chair leg

Then build the habit: Every time your dog goes to an approved chew toy unprompted, mark it (a quiet "yes" or a click) and drop a treat near the toy. You're teaching that choosing this object is the game. Do this 5 minutes a day during your normal evening routine — it doesn't require a formal training session.

"More exercise is the answer"

Physical exercise is healthy and necessary, but for a collie, brain work is the real currency. Research into breed-specific cognition consistently shows herding breeds need to think, not just move.

A 90-minute walk with nothing to figure out can leave a collie more wound up than a 20-minute walk followed by 10 minutes of structured mental work. The reason: aerobic exercise raises adrenaline and cortisol. Problem-solving and calm engagement lowers them.

Reality: swap some physical time for brain time, and you'll likely see chewing drop within a week or two.

What works:

• Scatter feeding — throw their breakfast kibble into the grass and let them sniff it out. Ten minutes of nosework is genuinely tiring.
• Stuffed Kongs or licki mats — freeze them the night before. A frozen Kong buys 20–30 minutes of calm, appropriate chewing.
• Short training bursts — 5 minutes of "find it," loose-lead work, or trick training before you leave the house. A collie who's just had to think settles much more easily.
• Rotate toys weekly — novelty matters enormously to this breed. A toy that was ignored last week becomes compelling again after a fortnight in the cupboard.

"He'll grow out of it"

Some do — around 2 to 3 years old, as the adolescent phase winds down. But waiting it out without changing the environment usually just means two or three years of destroyed furniture, and a dog who has practised chewing inappropriate things thousands of times. Habits that are rehearsed are habits that stick.

There's also a proportion of collies whose chewing is driven by anxiety rather than boredom, and anxiety doesn't resolve on its own. Signs that anxiety (not just boredom) may be driving the behaviour: chewing is focused near exits or windows, your dog shows other signs of distress when alone (barking, pacing, toileting inside despite being housetrained), or the chewing escalates rather than improving with enrichment.

Reality: early intervention is faster and kinder than waiting. The approach above — management, then redirection, then enrichment — typically shows clear improvement in two to four weeks when applied consistently.

If you've been at it for four to six weeks with genuine consistency and things aren't shifting, or if you suspect separation anxiety is in the mix, that's the point to bring in a veterinary behaviourist or a certified applied animal behaviourist (look for CAAB or IAABC credentials). Separation anxiety in particular responds well to a structured desensitisation protocol, but it needs proper diagnosis first — the over-the-counter advice online for it is, frankly, all over the place.

What a realistic daily routine looks like

• Morning: Scatter-feed breakfast in the garden — 10 minutes, zero effort from you
• Before you leave: 5-minute training session (any cue your dog knows), then a frozen Kong in their space
• Evening: One short walk plus 5 minutes of trick work or a sniff game indoors

That's it. You don't need to overhaul your life — you need to make the right choice easier than the wrong one, for both of you.

Border collie destructive chewing almost always has a solution. You haven't ruined your dog. You've just been given the wrong map.
