FAQs Breed Size Guide

Although we recommended pets are measured first, we know that this isn't always possible when buying pet collars and clothes as gifts or for new puppies.

The size chart below is a guide only, as all pets are unique and therefore may not fit into their breed's 'standard' size. Within breeds, there will be some size variation between the genders with females being smaller (sometimes one or two sizes smaller than males of the same breed.)
