Where to measure: the widest part of your dog's chest, just behind the front legs, and the base of the neck.
No measuring tape? Use a piece of string, then measure the string.
Between two sizes? We recommend sizing up.
Weight is only a guide. Dogs of the same weight can have very different body shapes, so always size by chest and neck measurements.
