Measure your dog. Weight is a sanity check, not a size. Two dogs at the same weight can be two sizes apart, and chest girth is what decides it.

Size	Body Length (in)	Neck (in)	Chest (in)	Suggested Weight (lbs)
XS	12	10	14	3 - 10 lbs
S	14	11	16	6 - 15 lbs
M	16	13	20	15 - 30 lbs
L	19.5	15	23	30 - 40 lbs
XL	21	17	27	40 - 50 lbs
2XL	23	19	31	50 - 70 lbs
3XL	26	21	35	70 - 100 lbs

How to measure

Chest goes all the way around the widest part of the ribcage, just behind the front legs. Neck goes around the base of the neck where a collar sits. Body length runs from the base of the collar to the base of the tail.

Fit: Button front with a soft notched collar and short sleeves cut to clear the front legs at a full stride. No opening at the back. If your dog lands between two sizes, take the larger one.

100% cotton, woven, no stretch. Same print as the Après Eras adult set.
