To find the right Top Paw harness size, measure your dog’s chest girth — the widest part of the ribcage, just behind the front legs — and match it to the size chart. Top Paw harnesses run from XS (toy breeds) to XL (large breeds), and when your dog falls between two sizes, you should always size up.
Here’s the full step-by-step.
Step 1: Measure chest girth
Wrap a soft tape measure around the widest part of your dog’s chest, right behind the front legs. Keep it snug but not tight. This is the single most important measurement for harness sizing.
Step 2: Measure the lower neck
Measure around the base of the neck where a collar would naturally sit. This helps confirm fit on adjustable styles.
Step 3: Match to the size chart
| Size | Best for | Approx. chest girth | Example breeds |
|---|---|---|---|
| XS | Toy breeds | 12–16″ | Chihuahua, Yorkie, Pomeranian |
| S | Small breeds | 16–21″ | Beagle, Shih Tzu, Dachshund |
| M | Medium breeds | 21–27″ | Border Collie, Cocker Spaniel |
| L / XL | Large breeds | 27–42″ | Labrador, Husky, German Shepherd |
Step 4: When in doubt, size up
If your dog’s measurement lands between two sizes, choose the larger one. The adjustable straps will tighten it down for a secure fit, whereas a too-small harness can’t be loosened beyond its limit and will be uncomfortable.

The two-finger rule
Once the harness is on, you should be able to slide two fingers flat between the strap and your dog’s body — snug enough that they can’t wriggle out, loose enough that it doesn’t dig in.
A note on puppies
Puppies grow fast. Re-measure every couple of weeks during growth spurts, and lean toward styles with generous adjustment range so the harness lasts longer.
