Outward Hound Granby Splash Yellow Dog Life Jacket is constructed with ripstop material that provides maximum buoyancy in the water and doesn't restrict movement on land.
Sizing Guide: Measure the widest part of your dogs girth and consider weight for appropriate buoyancy. If on the higher end, size up. Since dogs come in various sizes and body shapes, make sure to take any other traits (large shoulders, long torso, etc.) into consideration.
X-Small: 11-15" Girth - 5-10 lbs.
