i think it's super cute too. Sadie's stretching is always front paws straight out and back arched up like a cat. and Bentley will first do that way and pause for awhile then he'll entend his back legs out and do the froggie crawl and drag his back legs behind him for a few. his whole belly touches the ground and drags along. it's super silly. he also likes to roll and flip on carpet and beds and couches we call it "rubbing his stink on things"
