How to Measure

Neck: Measure around the widest part of your dog’s neck, allowing enough room for two fingers to slide under for a snug but not tight fit (this is usually an additional 2cm to be added to the measured length)

Chest: Measure right around the body around the deepest part of your dog's chest (this is usually just behind the dog's front legs).
