How To Measure
Measure from Base of Neck to Base of Tail to determine sizing.
Stand dog squarely. Measure with head up. Have your dog look straight ahead and find the spot where the neck joins the body. Measure from this point to the base of the tail(where tail joins the body) Blankets are sized every 2 inches from 10" to 28". Find the closest size to your measurements. If your dog's tail goes up (like a poodle or Jack Russel) go down to the nearest available size. If the tail goes down go up to the next size.
