SIZE GUIDE
SMART-FIT HARNESS SIZE CHART
Our harness is adjustable on all four straps so be sure to measure your dog to get the best fit.
Details on where to measure your dog's body are in the diagram below. Aim for a snug fit leaving space for two fingers between the measuring tape and your dog's coat.

Neck size – gently place the tape measure around your dog’s neck just below where a collar would sit
Chest size – place a tape measure gently around your dog’s chest at its widest point, normally just behind the front legs around the ribcage
IMPORTANT – The Dog Breed Size Guide is intended to give you a general guide of the size each breed can fit, however, we always recommend measuring your dog so you can choose the best size option for your dog. Note: the Breed Size Guide is based on fully grown dogs, sometimes a dog breed can show in two sizes due to variations in build and gender.
