Chuckit! - Ultra Squeaker Ring. The unique topspin infused action causes the Chuckit! Ultra Squeaker Ring to erratically bounce, zig, zag, & hop on the ground just like real game, engaging your dogs natural chase instinct. When caught, the squeaking sounds reward your dogs instinctual curiosity. The squeaking chamber on the Ultra Squeaker Ring is designed to fall into the toy in the event it becomes dislodged, making it safer during games of fetch.
