Why Does My Dog Chew the Leash & How to Stop It

Why Dogs Chew Leashes

Dogs chew leashes for several reasons, primarily rooted in instinct and development. Puppies often chew during teething, as gnawing helps relieve discomfort from new teeth coming in—just like human babies. Older dogs may chew due to boredom, pent-up energy, or anxiety, especially if they haven’t been taught what’s appropriate to chew. Some dogs also explore their world through their mouths, as their sense of taste and touch develops early in life. This natural curiosity can lead them to chew on anything within reach, including leashes. In some cases, leash chewing may be linked to separation anxiety or stress, where chewing becomes a coping mechanism.

How to Stop Leash Chewing

The key to stopping leash chewing is not punishment, but redirection and training. First, supervise your dog closely—especially during walks or when the leash is present. If you catch your dog chewing the leash, calmly redirect them to a safe, approved chew toy. Use a cue like “chew” or “toy” to help them associate the behavior with the correct object. Immediately click and reward them when they switch to the appropriate toy. This positive reinforcement helps build the habit over time. Consistency is essential: repeat this process every time the behavior occurs.

Prevention and Environmental Control

Preventing access to the leash when not in use is a smart first step. Store leashes out of reach when not walking your dog—on a hook, in a closet, or behind closed doors. This reduces temptation and prevents the behavior from becoming a habit. For puppies, prevent access to all tempting items by using closed containers, toy boxes with lids, or locking trash bins. Make sure your dog always has safe, durable chew toys available—such as rubber toys, antlers, or vet-approved chews—so they have something appropriate to chew on when bored or stressed.

Training with Positive Reinforcement

Use clicker training to reinforce good choices. Gather your clicker and treats, and have several approved chew toys on hand. When your dog starts chewing the leash, calmly replace it with a safe toy. Click and treat the moment they show interest in the correct toy. Repeat this consistently to help your dog make the connection between the right behavior and the reward. Over time, introduce the cue “chew” or “toy” before offering the toy, so your dog learns to respond to your command. This method works for dogs of any age and helps build lasting habits.

When to Seek Help

If chewing persists despite consistent training, or if you suspect anxiety, fear, or separation issues are behind the behavior, it may require deeper intervention. Dogs chewing due to anxiety or panic need specialized support beyond basic training. In such cases, consult a professional trainer or veterinarian to address the root cause. Never use harsh tools like prong collars or bitter sprays without understanding the underlying reason—these only treat symptoms, not the cause.
