Original Review August 10, 2019: (update below) Bailey is a Havanese/Pomeranian mix. When she went for her first hair cut, the groomer shaved her down instead of the trim and dematting I requested. This left the little 2.8 lb. puppy very cold. This sweatshirt (XS) fit her perfectly and kept her warm without her walking out of it like some others I tried. The sweatshirt material doesn't snag like a sweater, the holes for the neck and front legs were snug but not tight so the garment stayed on her like it should regardless of how rough she played with our other dog. If there was one thing that would make it even better - I'd ask for it to be available in more colors. Well worth the money spent!Updated Review: February 28, 2023 - Bailey is now full grown and topped out at 4.3 lbs. She still loves her sweatshirts so I'm here to buy more. The sweatshirts wear well, they do pill a little after washing (even washing inside out and inside a garment bag), but I just take them off with a little tape. Bailey finally grew into the X-small size shirt. I'd like it if the back were a little longer but otherwise, these are well made and a good buy.
