<h1>How to Choose the Right Harness Size for Your Dog: Vet Fit Guide</h1>
<p>Choosing the right harness size isn’t just about comfort—it’s about safety, control, and avoiding escapes.</p>
<p>As a veterinarian and product designer at <a href="https://woopf.com" target="_blank">Woopf</a>, I’ve seen firsthand how an ill-fitting harness can cause everything from skin irritation to serious injury. Let’s break down exactly how to measure your dog and find their perfect fit.</p>
<h2>📏 What You'll Need</h2>
<ul>
<li>A soft measuring tape (or string + ruler)</li>
<li>Your dog standing in a natural position</li>
<li>Our <a href="https://woopf.com/pages/size-guide" target="_blank">Woopf Size Guide</a></li>
</ul>
<h2>📐 Key Measurements</h2>
<h3>1. Chest Girth (Most Important)</h3>
<p>Measure around the widest part of your dog’s chest—usually just behind the front legs. This determines your dog’s primary size range.</p>
<h3>2. Neck Girth</h3>
<p>Measure the base of the neck (not where a collar sits). This helps ensure the harness won’t choke or restrict breathing.</p>
<h3>3. Body Length (Optional)</h3>
<p>Measure from the base of the neck to the base of the tail—especially helpful for deep-chested or long-bodied dogs like Dachshunds, Greyhounds, or Whippets.</p>
<h2>🧠 Vet Tips by Body Type</h2>
<ul>
<li><strong>Deep-chested dogs</strong> (Greyhounds, Dobermans): May need to size down in girth but up in strap adjustability</li>
<li><strong>Stocky breeds</strong> (Staffies, Bulldogs): Ensure wide chest padding and generous belly adjustment</li>
<li><strong>Small/toy breeds</strong>: Use soft fabric harnesses like the <a href="https://woopf.com/products/sherpa-harness" target="_blank">Sherpa Harness</a></li>
</ul>
<h2>✅ Harness Fit Checklist</h2>
<ul>
<li>You can fit two fingers between any strap and your dog’s body</li>
<li>The harness doesn’t shift side to side when walking</li>
<li>No gapping near the chest or underarms</li>
<li>Dog can sit, walk, lie down, and turn comfortably</li>
</ul>
<h2>🚨 Signs of a Poor Fit</h2>
<ul>
<li>Hair loss or redness under straps</li>
<li>Dog freezes or refuses to walk when harnessed</li>
<li>Harness slides around the body or over shoulders</li>
<li>Dog can back out or twist free</li>
</ul>
