Making sure your pug’s harness fits well is all about comfort and safety. With their short necks and wide chests, pugs don’t always match “small dog” sizes. A harness that’s too loose can slip right off, while one that’s too tight puts pressure on their breathing. Luckily, a quick set of measurements will help you get it right the first time.

🔍 Why Measuring Matters for a Pug Harness
Pugs have a unique body shape—round chests, short necks, and compact builds. That’s why sizing charts don’t always match up. Taking the time to measure means fewer returns, less frustration, and a happier pug who enjoys walks without discomfort.
🔍 How to Measure a Pug for a Harness
You only need a soft tape measure and two quick checks:
- Chest girth: wrap the tape around the widest part of your pug’s chest, just behind the front legs.
- Neck: measure where a collar naturally sits.
These numbers are your guide when comparing harness charts. For puppies, repeat the measurements every few weeks as they grow.
🔍 What Size Harness Does a Pug Need?
Most adult pugs fall into a small or medium, with girth usually between 16–22 inches. Always compare with the brand’s chart before buying. If your pug is between two sizes, size up and tighten the straps for comfort. Puppies do best with adjustable harnesses that grow with them.

🔍 Tips for Measuring Pug Puppies
Puppies grow fast in their first months, so check the fit often. Measure chest and neck just like with adults, but expect quick changes. A good test is slipping two fingers between the harness and your puppy’s body—snug, but not tight. Adjustable harnesses save you from constant upgrades.
🔍 When to Replace or Upgrade a Harness
Harnesses don’t last forever. Watch for frayed straps or weak buckles. If your pug gains or loses weight, the fit can change, and it may be time for a new one. Puppies will definitely outgrow their first harness, and even adult pugs might need an update if walks start looking uncomfortable.
