The Chuckit!® Rugged Flyer is designed to withstand tough dogs and rough play. The rigid polypropylene core provides durability and strength, while the over-molded TPR ridges allow your dog's teeth to grip the toy without puncturing it. Also, the Rugged Flyer's ergonomic shape provides easy pickup and retrieval for your dog. The Rugged Flyer floats, making it great for both land and water play! Bright color provides high visibility for dogs.
