How to measure the dog size?

Chest: measure the thickest part of the chest, add 2-3CM (1 inch) 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 (2 inch) front the base of the tail.

Neck: the girth of the neck, add 2-3CM (1 inch) 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.
