No need to worry about your dog on or off shore. Comes with two adjustable straps for superior fit and comfort, and the handles make it easy to lift your dog out of the water. The buoyancy collar is designed to keep Fido's head above water, and the "collar to tail" back zipper ensures easy on and off. The easy care nylon shell dries quickly, and the vented mesh bottom helps keep your dog cool. Just measure the circumference of the chest behind the front legs at the deepest point to determine the right fit.
