The Fattie Bearz Tea Cup 6-13 lb gray doggie sweater is a stylish and cozy option for tiny or small dogs like Yorkshire Terriers weighing between 6-13 lbs. Made from a comfortable cotton blend material, this sweater is designed to keep your furry friend warm and fashionable. The cute design and unique brand make it a charming choice for pet owners looking to dress up their small dog in a warm sweater. I’m not too sure if this would fit a 13lb dog. It was too large for my 3lb yorkie, however, I never got around to sending it back. It has never been worn or tried on as I could just tell it was too large. It did not come with tags, only the packing slip in the photos.
