Why Does My Dog Chew on Their Harness? Common Causes and Solutions

Quick Answer

Dogs chew their harnesses because of discomfort, anxiety, boredom, or a simple habit. Start by checking the fit and material, then address the underlying cause with training and positive reinforcement. If chewing persists, consider a chew-resistant alternative like the Freemotion harness and supervise all wear.

It’s a familiar scene: you turn your back for a minute, and your dog has turned their new harness into a chewed-up mess. While frustrating, this behavior is common and usually fixable. The key is to understand why your dog chews on their gear before you can stop it.

Chewing on a harness can be a sign of discomfort, anxiety, or simply a way to pass the time. It can also be dangerous if your dog ingests fabric or buckles. In this guide, we’ll walk through the most common causes and provide practical solutions, including training tips and safer product choices.

Why Dogs Chew on Their Harness

Dogs explore the world with their mouths, and a harness is a novel object that smells like you, other animals, and the outdoors. Puppies, in particular, may chew as part of teething or as a way to learn about their environment. Adult dogs might chew out of boredom, especially if the harness is left within reach when they’re alone.

Another common cause is discomfort. A harness that rubs, pinches, or restricts movement can cause your dog to try to remove it by chewing. Anxiety is another trigger – some dogs chew as a self-soothing behavior when they’re stressed or overstimulated. Finally, some dogs simply develop a habit of grabbing the harness during walks or play, which can be reinforced by your reaction.

• Check for red marks or fur loss under the harness after removing it – these are signs of chafing.
• If your dog only chews when you’re not looking, they may be bored or anxious.

How to Stop the Chewing: Training and Management

Start by making the harness a positive part of your dog’s routine. Use treats and praise when they sniff or wear it, and never force it on. If your dog chews during walks, redirect their attention with a toy or a quick training command like 'leave it.' Consistency is key – reward calm behavior and ignore attention-seeking chewing.

Management is just as important. Keep the harness out of reach when not in use, and supervise your dog while they’re wearing it. If your dog chews when you’re away, consider crate training or using a safe chew toy as a distraction. For severe anxiety, consult a veterinarian or a professional dog trainer for a tailored behavior plan.

• Apply a bitter-tasting deterrent to the harness (test on a small area first) to discourage chewing.
• Rotate toys to keep your dog mentally stimulated and reduce boredom-related chewing.

When to Consider a Chew-Resistant Harness

If you’ve addressed fit, comfort, and behavior but your dog still chews, it may be time to choose a more durable harness. Look for materials that are tough yet comfortable, and designs that minimize pressure points. A well-fitted harness that your dog can’t easily grab may also reduce the urge to chew.

The Freemotion harness is a good option for active dogs. It’s designed for high-performance activities like bikejoring and canicross, but it works for any family dog. Its adjustability helps ensure a snug, comfortable fit, which can reduce discomfort-related chewing. However, no harness is completely chew-proof, so supervision and training remain essential.

• Choose a harness with padded sections to reduce chafing and make it more comfortable to wear.
• Avoid leaving any harness on your dog for extended periods without a break.

Diagnosing Your Dog’s Harness Chewing

• Symptom: Your dog chews on the harness during wear, when left alone, or when it's stored within reach. Observe when and where the chewing happens to narrow down the cause.
• Likely Cause: Discomfort from poor fit, boredom, anxiety, or a learned habit from past reinforcement. Check the fit first – a too-tight or too-loose harness is a common culprit.
• Corrective Action: Adjust the harness for a snug, comfortable fit. Use positive reinforcement training, provide mental stimulation, and supervise wear. Keep the harness out of reach when not in use. If the chewing stops, you’ve solved the problem. If it continues, move to the next step.
• Stop or Choose Another Option: If training and management don’t work, consider a more durable harness like the Freemotion, but remember that no harness is indestructible. If your dog ingests material or shows signs of distress, stop using the harness and consult your vet. Safety first – don’t risk your dog’s health for the sake of gear.

Harness Alternatives That May Help

• Freemotion harness: Our original harness design is developed, tested, and used by world-leading mushers within bikejoring, skijoring and canicross, but applies to any active family dog. Freemotion comes in a variety of sizes and has good adjustability to fit most breeds. A better fit reduces chafing and discomfort, which are common triggers for chewing. The durable construction also withstands more wear and tear.

Chewing on a harness is a solvable problem. Start by understanding the cause, then apply the right training and management techniques. If needed, upgrade to a more comfortable and durable harness, but always prioritize your dog’s safety and well-being.
