How Do You Choose a No-Pull Dog Harness Between Two Sizes?
Short answer: Use your dog's measured chest girth first, then check where the measurement falls within the overlapping supplier ranges. Do not simply size up by breed or weight; a harness that cannot be adjusted securely may rotate or allow escape.
Why this matters
ShopWithFun's verified chest chart lists S at 33–63 cm, M at 40–72 cm, L at 47–86 cm and XL at 55–100 cm. The overlaps are substantial, so a single chest number may fit more than one labeled size. The better choice is the size you can adjust snugly without pinching or restricting shoulders.
What to check
- Measure around the widest part of the ribcage just behind the front legs, with a flexible tape.
- Compare the real chest value with both candidate sizes, then examine strap placement and adjustment range.
- After fitting, check rubbing and remeasure if your dog is growing or between seasonal coat lengths.
Practical takeaway
Supplier weight suggestions are secondary. If you cannot verify a secure fit from the available measurements, contact the seller before ordering rather than guessing.
