I don’t have PAWS but I have Muttlucks. Beckie is 8.3 lbs and Merlin 6 lbs. They both are around 11 in high and they both wear the smallest size Muttlucks. I think Paws are made to be tight, and they are very hard to put on if you don’t have Paws Jaws from what I read on this forum. I would buy one. I suppose you need the smallest size for it as well.
