HOW TO MEASURE

Got a fabric measuring tape?
Perfect! Wrap that sucker around your dog's chest at the widest part of their ribcage. Then, add 1" for comfort. Between sizes? Choose the larger size.

No measuring tape? No problem!
Grab a piece of string (or anything string-ish). Wrap it around your dog's chest at the widest part of their ribcage. Mark the string where it overlaps. Then measure it with a ruler. Add 1" for comfort. Voilà! You've found the perfect harness size.
