How to measure the dog size?

Chest: measure the thickest part of the chest, add 1~2CM will be better. (Usually behind the two legs)
Length: Make sure your dog stands properly, not sitting or lying. Measure along the dog's backbone from the base of the neck to 5CM front the base of the tail.
Neck: the girth of the neck, add 2~3CM will be better.

Note: If your dog is a large chest, long hair, or at the high end of the size, you may order the next larger size to ensure a comfortable fit.
