Our Sniff and Snack Quiz Ball is designed with pockets on alternate sections of the ball. You are able to slide treats into the pockets giving your dog more of a challenge. The Sniff and Snack Quiz Ball needs engagement from your dog unlike traditional treat dispensing toys the Quiz Ball doesn’t freely distribute the treats/Food. Supervision is required. These toys are not designed as tug toys and once your dog has finished finding their treats/Food remove the quiz ball from your dog.
