A rolling ball is great. A rolling ball spilling treats? Yes, please! With the Busy Buddy Twist 'n Treat Dog Toy, pet parents control the size of the opening, making it possible to use with any size or type of treats. Kibble or treats are randomly dispensed as dogs bat, chase, and chew their way to a belly full of the good stuff! Twist 'n Treat Dog Toys are available in multiple sizes.
