How to Fit a Dog Harness 2025: Vet-Approved Step by Step Guide 🐶✨
By Dr. Duncan Houston BVSc
A poorly fitted harness isn’t just uncomfortable—it’s unsafe. Whether it causes chafing, restricts movement, or allows your dog to slip out, bad fit is one of the top reasons harnesses fail.
I’m Dr. Duncan Houston, veterinarian and founder of Woopf. I’ve seen the clinical consequences of gear that doesn’t fit: armpit sores, shoulder strain, and even lost dogs. That’s why I designed the Explorer Harness with adjustability, security, and anatomical comfort in mind—and why fitting it correctly matters just as much as buying it.
Here’s how to get it right, step-by-step.
📏 Step 1: Measure Your Dog Before Ordering
- 🐶 Neck: Measure around the base of the neck—not high on the throat
- 🐕 Chest/Girth: Measure the widest part behind the front legs
Compare your dog’s measurements to the sizing chart on the Explorer Harness product page. If your dog is between sizes, size up and adjust down for a snug fit.
🎽 Step 2: Adjust the Harness While It’s Off the Dog
- Loosen all straps before first use
- Unclip all buckles (Explorer clips on both sides—no need to go over the head)
This makes initial fitting easier and less stressful, especially for nervous dogs.
🧩 Step 3: Fit the Harness Onto Your Dog
- The neck loop over your dog’s head if needed (or clip around the neck)
- Bring the belly straps under and around the chest
- Clip both side buckles behind the front legs
⚙️ Step 4: Adjust the Straps
- 🔒 Neck: Should be snug but not tight—2 fingers should fit under easily
- 🦴 Chest Girth: Should sit behind the front legs without rubbing the armpits
- 🟰 Straps: Adjust evenly on both sides to keep the harness centered
🧪 Step 5: Perform a Fit Check
- 👆 Can you fit two fingers under every strap? If not, loosen.
- 🧍 Does the harness move side to side when your dog walks? If yes, tighten slightly.
- 🪢 Is the chest strap sitting too far forward or riding up? Rebalance the girth vs neck fit.
The harness should move with your dog, not bounce, shift, or dig in.
🚫 Common Fitting Mistakes (and Fixes)
- ❌ Harness too loose: Dog may escape or harness may twist. ✅ Tighten all four points.
- ❌ Chest strap in armpits: Causes rubbing and sores. ✅ Adjust rear straps to sit back farther.
- ❌ Harness rotates: Often due to uneven neck and girth straps. ✅ Recenter and balance both sides.
📦 Bonus: How the Explorer Harness Design Helps
- ✅ 4-way adjustment = custom fit for any body shape
- ✅ Y-front design avoids shoulder restriction
- ✅ Padded straps prevent chafing under arms and across the chest
- ✅ Escape-resistant when fitted properly
📊 Proper Harness Fit vs Improper Fit
| Fit Area | Improper Fit | Proper Fit |
|---|---|---|
| Neck | Too loose = rotation Too tight = choking |
Snug with 2 fingers room |
| Girth | Sits too close to armpits = rubbing | Sits behind front legs with padding |
| Side Balance | One strap shorter = twisting | Even strap length = centered fit |
