Familiarity: I've used it several times
Ditto what everyone else has said. BUT, I think this runs large compared to other Ruffwear items. My 85lb Lab/Shepherd barely fits into the size large harness, so I got this in an XL and it's pretty big on her. I think she tolerates it slightly more because it's a bit baggy, but maybe size down.
