Measure around the widest part of your dog's chest (just behind the front legs) and around the neck where the collar sits. Frenchies and pugs usually have deep chests and thick necks, so go by the chest measurement first and compare it with the size range on each product page. Between two sizes? Size up for harnesses.

Everything in the shop is picked with flat-faced breeds in mind, and each product page lists its measurement range. Still not sure? Send us your dog's breed, weight and chest size and we'll help you choose.
