Where to measure

CHEST GIRTHdeepest part of the ribcagejust behind the front legsNOT THE NECK
Snug against the coat, not pulled tight through it. Measure with your dog standing. Let the dog settle, then check the reading again.

Why a card and not a screenshot

A screenshot of a size chart is one brand’s answer with no way to check it. The card carries the measurement itself, every brand’s size for that measurement, and where the dog sits inside the recommended range. A size label applies to the named product or chart scope; check its source before ordering.
