The Chuckit Crunch ball Duo-Tug combines the popular Crunch balls from Chuckit with a thick rope for extra pulling and twisting fun with your dog. The balls contain the famous crackling material, which makes the balls crackle and creak during play and triggers the dog's instinctive curiosity. Thanks to the sturdy rope, you can play a tug-of-war with your dog, strengthening the bond between you and your dog, but it is also possible to fetch. Because of the size of the balls, the Chuckit Crunch ball Duo-tug can be combined with all Chuckit Ball Launchers in size M!
