ChuckIt! Amphibious Shark fin's stand out among dog toys and are designed for exceptional visibility and performance in water and on land. Each brightly-colored fin floats, will sail through the air with ease, and is easy on a dog's mouth. New Self-Righting technology results in an even higher level of visibility and stimulating action. No matter how these toys land on the ground or in water, they spring into an upright position. This line encompasses great versatility for the game of fetch.
