Activity toys that are perfect for activating your small or large dog. The ball can be used by all sizes. The treats are fixed inside and between the grooves on the ball, after which the dog can spend between 10-30 minutes getting all the treats out of the grooves (depending on how skilled your dog is at this). We recommend using a medium sized treat for the ball. If the treats are too small, it will be too easy for your dog to get the treats free. Size: 10 cm Ø
