Even pups who love to swim need the safety of a life jacket when they’re in or around the water! This stylish flotation jacket combines comfort and security, with adjustable nylon straps, a grab handle for added safety, and reflective strips for maximum visibility. Designed for easy on and off, with quick-release buckles and heavy-duty hook and loop fasteners around the neck and belly. Rugged nylon. For a correct fit, measure your dog’s length (from collar to the base of his tail), neck (around the base of his neck) and girth (at the widest part of his rib cage). Medium size is 14" l and fits dogs from 20-50 lbs. (20-25" neck, 21-30" girth).
