Measure your dog before ordering. That way you pick the right size on the first try. Unit: centimetres.

How to measure your dog

• Chest circumference: wrap the tape around the widest part, just behind the front legs.
• Neck circumference: measure at the base of the neck, at the widest point.
• Back length: from the top of the shoulder blade to the base of the tail.

Tip: keep your dog standing with head naturally raised while measuring. Breeds are indicative. Between two sizes, pick the larger one — comfort wins.
