How to Fit a Harness Properly (and Why It Matters)

You've picked the perfect harness. It's stylish, it's sturdy — it's everything you and your dog deserve.
But even the best harness won't work if it doesn’t fit properly.
(And yes, your dog will find a way to wiggle out if it’s too loose.)

Today, we’re covering exactly how to fit a harness the right way — plus why getting that fit just right keeps your pup safe, comfortable, and looking sharp on every adventure.

Why Proper Harness Fit Is Everything

Before we get into how to fit it, let’s talk about why it matters so much:

  • Safety:
    A loose harness can lead to dangerous escapes. A harness that's too tight can restrict breathing and movement. Neither is a good look (or feel) for your best friend.

  • Comfort:
    A well-fitted harness moves with your dog, not against them. It prevents rubbing, pinching, and chafing — no more sad puppy eyes on walks.

  • Training Success:
    If you’re working on leash manners (hello, no pulling!), a properly fitted harness gives you gentle control without discomfort.

  • Long-Term Health:
    Dogs’ bodies are sensitive — especially smaller breeds or pups prone to trachea or spine issues. A poorly fitted harness can cause strain over time.
    (Think of it like wearing shoes two sizes too small — ouch!)

Bottom line:
A harness should fit like a comfy hug — secure but not squeezing.


Step-By-Step: How to Fit Your Dog's Harness Perfectly

1. Measure Your Dog First

Never "eyeball" it. Different brands have different sizing.
Grab a soft measuring tape and take two key measurements:

  • Chest girth: Around the widest part of the ribcage (just behind the front legs)

  • Neck girth: Around the thickest part of the neck, where a collar would naturally sit

Write them down — and compare with the brand’s sizing chart.
(Tip: Dogistry’s harnesses have an easy-to-use sizing guide to help you nail it!)


2. Adjust the Straps (Yes, All of Them)

When you first put the harness on, it may feel a little “off.” That’s normal — it’s designed to be adjusted!

✔️ Neck Straps: Should sit comfortably around the base of the neck, not up by the ears.
✔️ Chest Straps: Should rest behind the front legs, not digging into the armpits.
✔️ Belly Straps: Should allow natural movement but feel snug enough that the harness doesn’t shift side-to-side.

How Tight Should It Be?

Use the two-finger test:
You should be able to easily slide two fingers between the strap and your dog’s body — no more, no less.

If it’s too loose, they might back out of it.
If it’s too tight, you’ll see indentations or your dog may act uncomfortable.


3. Check for Smoothness and Balance

Before you head out:

  • Ensure the harness sits evenly across your dog’s body.

  • Adjust any twisted straps.

  • Tug gently at the harness — it should stay in place without shifting awkwardly.

🎯 The Goal: A balanced fit where your dog can move, breathe, sit, and play normally.


4. Watch Them Walk

Now the real test: go for a mini stroll around the yard or living room.

Is the harness:

  • Staying put without sagging or riding up?

  • Allowing full movement without rubbing?

  • Keeping your dog happy and tail-wagging?

Adjust slightly if needed — a few minutes now can save a lot of frustration later!


Signs Your Dog's Harness Doesn't Fit Right

Not sure if you’ve nailed it? Watch for these red flags:

  • Frequent slipping or shifting

  • Pawing at the harness

  • Chafing, redness, or hair loss around the straps

  • Struggling to walk naturally (e.g., stiff legs, short steps)

If you spot any of these, it’s time for some tweaks — or maybe a new size or style altogether.

A Few Bonus Vet-Approved Tips

  • Puppy Parents: Puppies grow fast — check harness fit every few weeks.

  • Seasonal Check: Dogs lose and gain weight too (especially after winter) — double-check fit seasonally.

  • Harness Style Matters: Step-in harnesses vs. overhead harnesses fit slightly differently — always follow the specific fitting guide for your style.

Minimal effort = maximum tail wags. 🐶✅
