Use this chart (the most important measurement is the barrel size):
Barrel Between Legs Body Length
Small 25 – 27″ 2 1/2 – 3″ 10 – 11″
Medium 27 – 29″ 3 – 3 1/2″ 11 – 12″
Large 29 – 31″ 3 1/2 – 4″ 12 – 13″
X Large 30 – 32″ 4 – 5 1/2″ 12 – 13″
How do I take measurements to ensure the best possible fit?
All measurements should be taken with the dog standing and the measuring tape against the body. Remember, you want the best fit possible. Our gear is designed to lie against the contours of the body – your measurements should be taken the same way.
1. Barrel – around the rib cage at the deepest part of the dog’s chest, behind the front shoulders.
2. Between the Front Legs – most dogs need a 2-3 inch width unless it is a special case.
3. Body Length – between the inside of the front leg to the inside of the back leg.
