Please use the following diagram for measuring your pet.
Note: For collars and harnesses, we suggest measuring loosely around girth and neck, as all restaining accessories should fit comfortably on your pet. For clothing, if your dog is stouter, you should follow the size according to the girth. Please remember to always round up to the next larger size if your measurement is near or over the maximum range in the smaller size, or you pet has a broad chest, wide underisde, or thick coat.
