Why Dogs Chew Leashes During Walks

Root Causes of Leash Chewing

Dogs often chew their leashes during walks because of underlying frustration or anxiety. This behavior can signal that their basic needs—such as adequate exercise, mental stimulation, or a consistent routine—are not being met. Overstimulation, inconsistent interactions, or insufficient sleep may also contribute. The use of aversive tools like prong, choke, or electronic collars can worsen anxiety and trigger chewing.

Additionally, leash chewing may be linked to excitement. Walks are thrilling adventures for dogs, full of new sights, sounds, and smells. When dogs are overly excited and eager to explore, they may redirect that energy into chewing the leash.

Boredom and Unmet Instincts

Boredom is a common driver of destructive behaviors, including leash chewing. Dogs naturally explore their world with their mouths—this is how they learn, especially as puppies. Chewing is instinctual; thousands of years ago, dogs needed to chew through bone and marrow to survive. Even today, many dogs retain this innate desire to chew.

If a dog lacks appropriate outlets, they may turn to the leash as a substitute. This is especially true if they were never taught as puppies what they should chew on. Without proper guidance, chewing becomes a habit, not just a response to pain or boredom.

Effective Management Strategies

To stop leash chewing, focus on prevention and redirection. One effective method is using a second leash: when your dog starts chewing, drop the first leash while maintaining control with the second. This avoids reinforcing the behavior while keeping you in charge.

Introduce a tug toy during walks as a distraction and mental outlet. Engaging in games that teach loose-leash walking also helps. These activities provide both physical exercise and mental stimulation, which can reduce frustration and anxiety.

Using longer leashes can also help, as they give your dog more freedom to explore safely without pulling or chewing.

Avoiding Ineffective Fixes

Using bitter sprays or prong collars may stop chewing temporarily, but they don’t address the root cause. These tools can increase anxiety and worsen behavior over time. True progress comes from understanding why the dog is chewing and teaching them better alternatives.

Consistency is essential. If you occasionally allow chewing, your dog will be confused. Supervise your dog closely, especially during walks, and redirect their attention immediately when they start chewing.

Training and Positive Reinforcement

Use positive reinforcement to teach your dog what to do instead of chewing. When your dog walks calmly with a loose leash, reward them with treats or praise. This reinforces the desired behavior.

You can also use a clicker to mark the moment your dog stops chewing or keeps their mouth off the leash. Pair this with a treat to strengthen the association.

Remember: your dog cannot chew your leash if you’re actively supervising or managing the environment. Be present, redirect attention, and offer acceptable chew toys.
