The Truth About Dog Harness Fit: Avoid These 5 Common Mistakes

The Truth About Dog Harness Fit: Avoid These 5 Common Mistakes

As dog harnesses grow in popularity—especially among small and medium-sized pups—we’ve noticed something important: more dog parents are making the switch, but not everyone is getting the fit right. And that can turn a walk in the park into a struggle (or even a safety risk).

Whether you're here for a stylish dog harness that turns heads, or a reliable one that keeps your pup secure, getting the right fit is non-negotiable. Let’s break down the five most common harness-fitting mistakes—and how to fix them. Your dog will thank you. 💛

 

1. Guessing Your Dog’s Size (Instead of Measuring)

We totally get it—your pup might be between sizes, or maybe you've ordered a harness before and want to wing it. But every harness design is a little different, and even a few inches can make a big difference.

What to do instead:
Take a few minutes to measure your dog’s chest girth and neck circumference with a soft tape measure.

👉 Here’s our simple guide on how to measure your dog for a harness
📏 Tip: Always measure when your pup is standing up for the most accurate fit, and if they are between sizes, opt for the larger size. 

 

2. Choosing Style Over Structure

Yes, we love a super stylish harness as much as the next person. But style should never come at the cost of comfort and safety. Ill-fitting or poorly designed harnesses can rub, pinch, or restrict movement.

What to do instead:
Look for harnesses that balance both—ours are made to turn heads and support proper movement. Features like adjustable straps, breathable materials, and Y-shaped chest panels help keep pups safe and stunning.

 

3. Ignoring Weight and Breed Factors

A harness that works beautifully on a Yorkie might be all wrong for a Frenchie. Body shape matters—and some breeds are notorious escape artists.

What to do instead:
Opt for a harness designed with your dog’s body in mind. Be sure to measure their chest girth and neck circumference using a soft tape measure—and don’t forget to check out our Testimonials for real-life fit stories.

📏 Tip: Use the filters in our Reviews section to sort by size, breed, and weight. It’s an easy way to see how our harnesses fit dogs just like yours.

 

4. Not Adjusting the Straps (or Adjusting Just Once)

Even a well-sized harness needs to be properly adjusted—and sometimes re-adjusted after a few wears, a bath, or a fresh groom. A poor fit can lead to rubbing, slipping, or a wiggly escape.

What to do instead:
Our harness is thoughtfully designed with 3 adjustment points—around the neck, chest, and belly—so you can customize the fit for your dog’s unique shape. Once clipped in, do a quick check:

  • You should be able to fit two fingers between each strap and your pup’s body

  • Make sure nothing is twisting, sagging, or pinching

Pro tip: Recheck the fit every few weeks—especially for growing pups or after grooming appointments. A small adjustment can make a big difference!

 

5. Overlooking Comfort 

If your pup constantly scratches at their harness or tries to back out of it, it’s a sign something’s off. Discomfort isn’t just frustrating—it can make walks stressful and unsafe.

What to do instead:
Choose a harness designed for all-day comfort, especially for daily walks and longer adventures. Ours is made with quick-drying neoprene and breathable mesh to keep your pup cool, even on warmer days. 

Our customers often tell us their dogs “forget they’re even wearing it”—and that’s exactly the kind of comfort your pup deserves. 💛

 

Why a Well-Fitting Harness is Worth It

A harness should make every walk feel better—for both of you. The right fit prevents pulling, reduces the risk of escape, and protects your dog’s neck and spine. Not to mention: it makes your pup look put-together and polished on every adventure.
