Review on Kurgo K9 Core Dog Sweater: Year-Round Fleece Vest for Dogs with Zipper Opening, Adjustable Neck, and Harness Compatibility by Elle Foster

Small and extra small sizes are for wide chested and short back dogs. Otherwise they look like tiny short sleeve t-shirts. The little one is said to be a perfect fit for my mini poodle but is about 6 inches shorter than I would like on the back and 2 inches shorter on the tummy. It's a small dog, meaning not that many inches are covered. The only part of his body he really fits on is his chest, which is also the only adjustable part of the sweater. You have a Pug, Frenchie, Cavalier King Charles Spaniel, Shih Tzu, or a dog with a similarly broad chest and short chest. then this sweater is perfect. If you have a small dog of any height, you might be better off with a Ruffwear or RC Pets sweater.
