Because the straps are adjustable by velcro, the best way to measure your dog is between the neck to tail.
This will give you an idea of how long the coat will be on your dog’s back.

Available Sizes:

XS / 30cm neck to tail / 40-48cm waist

SM / 34cm neck to tail / 45-54cm waist

MED / 38cm neck to tail / 53-64cm waist

These coats are made for little hunds under 10kg.
