The Chuckit!® Hydroflight is designed to hold and release water during play when thrown. This innovative water toy helps keep dogs cool in warm spring and summer weather - the coolest way to fetch! The oversize bright orange color design provides high-visibility on water or on land. The disc is made from buoyant foam and floats, even while full of water. The foam construction is firm enough to maintain its shape yet soft enough for a dogs mouth. Made using abrasion-resistant materials to stand up to the most eager dog. The one size is suitable for most breeds and sizes of dogs.
