Hide N' Slide puzzle game is a fun way to engage your pup's mind and activate their problem solving-skills. This level 2 intermediate puzzle dog toy comes with two types of hiding spots for snacks or kibble for a total of 14 treat compartments: under the swivelling flippers and in the hollow sliding blocks. You can vary the difficulty level by placing treats just under the flipper for newcomers. And once your puppy gets the hang of it, you can increase the challenge by placing the treats in the hollow block, and watching your dog try to figure out how to slide it back and forth to release the treat into the flipper compartment. Made from food safe materials that are BPA, PVC and phthalate-free so you can feel safe playing with your dog over and over again! Easy to clean with warm water and soap.
