Woohoo, just my luck I managed to find out of both pet shops, and lots of harneses, one that acually fit Izzy! It's an Ezydog xxs! Hehe. Plenty of adjustment in it to grow, and plenty of time to get her used to it before she starts puppy classes on the 6th I ended up ordering her a medium heart tag, it can go on her harness if it's too big for her collar. Then we are all set for puppy class. I wonder if she will be the smallest there?!
