Grab a measuring tape and loosely measure your pet's neck and chest. Make sure to leave some wiggle room (about two fingers thick). Have a fluffy dog? Either measure around their fur or add approximately 5 cm to their neck size. Chest size is measured at the widest part of your dog's check, just behind the front legs.
If in between sizes, consider ordering a size up.
