Quick Answer: Measure two things: chest circumference at the widest point behind the front legs, and neck circumference. Compare both measurements to the harness size chart — use the larger of the two measurements to determine size. When your dog falls between sizes, always go up. A too-small harness is uncomfortable and doesn't work correctly. A slightly large harness can be cinched down.
Step-by-Step Measuring
- Use a soft measuring tape (or a piece of string measured against a ruler)
- Measure the neck at its circumference — not the thickest part of the head, but where the collar sits
- Measure the chest at its widest point — this is directly behind the front legs and armpits
- Compare both measurements to the size chart provided in the product listing
- If one measurement puts you in a larger size — use the larger size
The Two-Finger Test
After fitting, run two fingers under every strap. Two fingers slide easily = correct fit. One finger only = too tight. Three fingers slide easily = too loose. This test is more reliable than size charts alone because dogs of the same weight have very different body shapes.
