The Importance of a Well-Fitting Harness for Your Dog

At Robin Bates Dog Training, we’re all about setting dogs (and their humans!) up for success. One of the most overlooked — but absolutely essential — tools in your dog-walking toolkit is the harness. And not just any harness — a well-fitting one.

You might be surprised how much difference the right harness can make to your dog’s comfort, behaviour, and safety. So let’s dive into why harness fit matters and how to make sure you’ve got the right one for your furry friend.

Why Fit Matters

Think of it this way: would you go for a jog in shoes that don’t fit? Probably not — and your dog feels the same way about an ill-fitting harness. A harness that’s too tight can rub, restrict movement, or cause pain. One that’s too loose can lead to escape attempts (and nobody wants a game of chase in the middle of a walk!).

Here are just a few reasons why a properly fitted harness is a must:

✅ Comfort: Your dog should be able to move freely without chafing or pressure on sensitive areas like the armpits or chest.

✅ Safety: A good fit helps prevent your dog slipping out of the harness, especially if they’re startled or excitable on walks.

✅ Better control: Especially for training, a well-fitted harness helps guide your dog without causing discomfort or creating negative associations.

✅ Support for training: Harnesses with front-clip options can be fantastic for loose-lead walking, giving you a gentle way to redirect pulling without resorting to harsh corrections.

Signs Your Harness Doesn’t Fit

If your dog is wriggling, refusing to walk, or constantly scratching at their harness, it could be a red flag. Here are some common signs it’s time for a fit check:

• The harness shifts side to side when they walk

• You can’t fit two fingers between the harness and their body

• It digs in under the arms or across the chest

• Your dog can back out of it easily

• They show signs of discomfort or irritation when wearing it

How to Check the Fit

A few quick checks can make a world of difference:

• Shoulders & legs: Your dog should be able to move their legs freely without the straps cutting into their joints.

• Chest strap: This should sit across the chest bone, not up on the neck or down on the belly.

• Two-finger test: You should be able to slide two fingers between the harness and your dog’s body comfortably — snug but not tight.

• Freedom to move: Watch your dog walk. Are they moving naturally and confidently, or do they seem stiff or hesitant?

Choosing the Right Type of Harness

There’s no one-size-fits-all solution, so here are a few options we often recommend:

• Y-front harnesses (like the Perfect Fit or Ruffwear Front Range): These allow natural shoulder movement and are ideal for most dogs.

• Front-clip harnesses: Great for training loose-lead walking, as they gently discourage pulling.

• Step-in harnesses: Often good for smaller breeds but can restrict movement in larger dogs.

We’re always happy to help you choose the right one — it’s all part of supporting you and your dog on your training journey.

Final Thought: Training Starts with Comfort

A good harness isn’t just about looks — it’s about creating a foundation of trust, comfort, and control. When your dog is comfortable and secure, they’re more likely to focus, learn, and enjoy walks with you.
