How to Measure Your Dog’s Gear: A Trail-Ready Guide from Cooper

I’ll never forget the day I tried to squeeze into a harness that was just a tad too snug.

Birdy and I were gearing up for an all-day trek through the Blue Mountains - sun shining, trails calling—but something felt off. My usually free-moving shoulders? Restricted. My chest? Squished. And the second I tried to leap over a rock, well… let’s just say it wasn’t my most graceful moment. Turns out, even the most adventure-ready pup needs a properly fitted harness.

Whether you’re a first-time dog parent or an experienced explorer looking for the perfect fit, getting the right size for your dog’s collar and harness is key. A good fit means comfort, safety, and all-day adventure readiness. So let’s break it down—step by step.

Why Fit Matters for Outdoor Dogs

Your human wouldn’t wear hiking boots two sizes too big or too small, right? The same goes for us! If a harness is too loose, we might slip out of it mid-adventure. Too tight? We can’t move freely, which means less zoomies, fewer happy tail wags, and a higher chance of chafing.

How to Measure Your Dog for the Perfect Fit

Here’s what you need:

• A soft measuring tape (or a string and a ruler if you’re improvising!)
• A treat or two (for motivation, obviously)

1. Girth Measurement (for Harnesses & Apparel)

This is the most important measurement for harnesses like the PawPlus Active Dog Harness. To measure:

1. Wrap the measuring tape around the widest part of your chest, just behind your front legs.
2. Make sure it’s snug but not too tight—your human should be able to fit two fingers between the tape and your fur.
3. Record the number and compare it to our sizing chart.

2. Neck Measurement (for Collars)

A well-fitted collar, like the PeakSec Dog Collar, should be snug but comfortable.

1. Wrap the tape around the base of your neck (where your collar naturally sits).
2. Like with the harness, two fingers should slide in comfortably.
3. If you’re between sizes, opt for the adjustable range that allows for some wiggle room.

3. Paw Measurement (For Boots & Adventure Gear)

If you’re gearing up for some serious terrain, knowing your paw size for boots can be handy.

1. Place your front paw on a piece of paper.
2. Have your human trace around it.
3. Measure the widest part of the outline.
4. Compare with size charts for the best fit!

What About Puppies?

Pups grow fast! If you’re in between sizes, sizing up is usually the best option. Most adjustable harnesses and collars—like those from Highfive Pet—can grow with you, making them a solid investment for your first year of adventures.

Final Fit Check Before the Trail

• Walk, run, jump—does your gear stay secure and comfy?
• Try the two-finger test again—if it’s too loose or too tight, adjust as needed.
• If in doubt, check the Highfive Pet Sizing Chart for guidance.

Gear Up & Get Out!

With the right fit, you’re set for epic adventures—no restrictions, no discomfort, just pure exploration. So measure up, strap in, and let’s hit the trail!
