Tempt your furry friend's ears and eyes with The Whistler Ball by Chuckit! This paw-some toy has unique cutouts that make a whistling sound too fun for any pooch to resist and unlike anything your pal has played with before. As it flies through the air, your dog will be ready to chase it down and hunt down that sound. They're made of durable, bouncy rubber that is easy to clean and fun to toss for a long-lasting fetch ball you and your pal can bond with. Designed to fit Chuckit! Launchers, so you and your pal can "go long" while you're gentle on your arm. Durable material is engineered for catching and fetching, so it can stand up to your rough-and-tumble tosses. The whistle sound is a great way to keep your pup entertained and make ball chasing more interesting. Easy to clean after a fun-filled day of fetch, so you can focus on relaxing with your best friend later on. Bright color gives increased visibility and help prevent ball from getting lost.
