The Roller is a great throw for reinforcing a dog with a disc.
Instead of flying through the air like a wing, the Roller rolls on the ground like a wheel; a fast, bouncy, super exciting wheel.
Dogs really like Rollers as reinforcement. Rollers make great cookies.
Rollers are also great teaching tools for the catch. They stand up and stay live for a long time and provide plenty of opportunity and interest for young or developing dogs.
Rollers make catching easy and exciting.
