A dog life jacket is a safety device designed to keep dogs afloat while they are in or around water. It is typically made from buoyant materials and features adjustable straps to ensure a secure fit. Many life jackets also come with handles, making it easier for owners to lift their pets out of the water if needed. These jackets are especially useful for dogs that are not strong swimmers or for those who enjoy water activities like boating or swimming. They come in various sizes and colors, allowing pet owners to choose one that fits their dog comfortably and suits their style.
