Kyjen Dog Games Cross Slider with Treat Ball is an interactive game for dogs that challenges them and teaches problem solving skills.
The treat dispensing ball goes into the slider toy, then your dog must slide the toy across the floor, trying to have the ball come out of one of the tunnels. Once the ball is free, it dispenses treats naturally through play. When your dog has figured out the toy, increase the challenge by adding up to three included doors, leaving only one tunnel open. This toy also works great with tennis balls!
My lab couldn't get the kibble out of the ball once he got it out of the toy. I couldn't even push them out of the ball with my fingers. Way too stiff.

My dog figures out puzzles and games within seconds. This one is at least a little challenging in that it takes some time to get the ball out and then once out, to get the treats. For the reviewer who says it's too hard, use smaller treats. I use my dog's kibble with one or two tiny pieces of hotdog to get his smeller going. Only complaint: the door guards are too easy to get off. He figured out how to swipe them off right away. Still one of my favorites.
