How To Measure Your Dog
For the best fit, we recommend taking three simple measurements before choosing a size.
Neck
Measure around the base of your dog's neck where their collar would naturally sit. Allow enough room to comfortably fit two fingers between the tape and your dog.
Chest
Measure around the widest part of your dog's chest, usually just behind the front legs.
Back Length
Measure from the base of the neck, where the collar sits, along the spine to the base of the tail.
BETWEEN SIZES?
If your dog's measurements fall between two sizes, always check the sizing advice provided on the individual product page. Fit can vary between brands and products, particularly with coats, jumpers and harnesses.
