Why Does My Dog Chew the Leash? Causes and Fixes

Quick Answer

Most leash chewing is excitement, boredom, or teething, not dominance. Stop the behavior by removing the leash from your dog's mouth calmly, redirecting to a tug toy, and rewarding four paws on the ground. If your dog keeps biting the leash after two weeks of consistent redirection, switch to a lightweight leash with a padded handle like the Urban Freestyle™ Leash and add short training walks before the behavior starts.

Why Dogs Bite Their Leash: The Three Common Causes

Leash biting usually falls into three buckets. Excitement: the leash predicts a walk, so your dog grabs it like a tug toy. Boredom or under-stimulation: the leash becomes the most interesting thing available. Teething or oral discomfort: puppies and adolescent dogs chew to soothe sore gums. Less common causes include frustration from a tight leash, pain from ill-fitting gear, or a learned game if chewing has previously earned attention. Watch when the behavior happens: at the door, mid-walk, or only when you stop moving. That timing tells you which cause you are dealing with.

How to Stop Dog Chewing Leash: A Step-by-Step Fix

Start before the walk. Put the leash on, stand still, and reward calm behavior for 10 seconds. If your dog grabs the leash, freeze, say nothing, and wait. The moment they release, mark with a calm 'yes' and reward. This teaches that holding the leash pauses the walk, while letting go restarts it.

During the walk, carry a small tug toy or treat pouch. When your dog targets the leash, offer the toy instead and reward chewing the toy. If your dog keeps biting the leash, stop walking and stand on the leash so it cannot become a tug game. Resume only when all four paws are on the ground and the leash is slack.

For puppies, keep sessions to 5–10 minutes and end before chewing starts. For adult dogs, increase physical and mental exercise: sniff walks, puzzle feeders, and training games reduce the boredom that fuels leash biting. Consistency matters more than intensity; two short sessions daily beat one long session weekly.

• Reward the behavior you want: a loose leash and a closed mouth.
• Never yank or jerk the leash; that adds excitement or pain and can worsen chewing.
• If your dog chews only when you stop, practice stopping and rewarding calm before you need it on a real walk.

Prevent Leash Chewing: Gear and Environment Choices

Some leashes invite chewing more than others. A lightweight, adjustable leash with a soft handle is less likely to be grabbed than a heavy, stiff one. The Urban Freestyle™ Leash from DOG Copenhagen is made from soft polyester webbing with a neoprene-padded handle, adjusts between 115 cm and 200 cm, and includes an accessory loop for pick-up bags. That adjustability helps you keep the leash short in high-distraction areas, which reduces the slack your dog can grab.

If your dog chews the leash mainly when you carry bags or treats, a hands-free or crossbody setup can help. The Urban Classic™ Leash is a 200 cm multifunction leash in vegan leather with dual aluminum carabiners and locking option, and it can be worn crossbody. That keeps your hands free to reward and redirect. For walks where you need to carry pick-up bags and treats, the Pouch Organizer™ leash bag attaches to the leash and keeps items secure with a built-in dispenser and two pockets, so you are not fumbling and your dog is not lunging for the leash while you dig for a bag.

When to Stop and Choose Another Option

If your dog shows guarding behavior over the leash, growls when you reach for it, or bites with enough force to cause injury, stop training and consult a certified behavior consultant or veterinarian. Leash chewing that appears suddenly in an adult dog can also signal pain or a medical issue. For puppies, if chewing continues past 12 months despite consistent redirection, a professional trainer can assess whether the cause is teething, frustration, or a learned game. Do not rely on aversive tools like spray or shock collars; they can suppress the behavior temporarily but often increase anxiety and make walks worse.

Leash Chewing Diagnosis: Match the Symptom to the Fix

• Grabs leash at the door or start of walk: Excitement and anticipation. The leash predicts fun, so it becomes a tug toy. Fix: put the leash on and stand still until your dog is calm. Reward four paws on the floor. Repeat until the door only opens when the leash is slack. If this does not improve in 3–5 sessions, add a quick play session before the walk to burn off excitement.
• Chews leash mid-walk, especially when you stop: Boredom or frustration with stopping. Your dog is looking for engagement. Fix: reward eye contact and loose-leash walking every few steps. Carry a tug toy and redirect. If your dog keeps biting the leash, stand on it to remove the game and wait for calm. If your dog only chews when you stop, practice stop-and-go games in low-distraction areas first.
• Puppy chews leash constantly, especially during teething: Teething pain or oral exploration. Fix: offer appropriate chews before and after walks. Keep leash sessions short and reward when the leash is in your hand, not their mouth. Use a lightweight leash that is less tempting to grab. If chewing continues past 12 months or causes damage, consult a trainer or vet for a behavior and health check.
