Dog puzzle will provide plenty of fun for your furry friends and encourage their natural hunting instincts. For pups who have mastered levels 1-2 and are ready to take on sequential step learning. Great for reducing destructive behavior in a fun and rewarding way! Who says learning can't be fun? With the dog twister plastic interactive dog toy, you can stimulate your pup's brain and have a blast at the same time! This unique toy is a challenging and fun game for you and your active dog. He has to look for treats by moving one block after another in different circles. Increase the degree of difficulty by locking the blocks with bone-shaped pegs, which are placed in the hollows all around the up-side of the game. He has to learn to unplug the blocks by lifting the pegs one by one in order to be able to move the blocks and then find the treats. He'll love the reward of a job well done, and you'll love watching him put on his doggy thinking cap!
