The Brainiac Disc-O isn't a dance-it's a treat dispenser that will keep your dog stimulated and engaged. Each round wooden toy has a circular track with 6 sliding discs; beneath the track are 5 treat compartments. Hide treats in one or more of the compartments, place the disc over them, and let your dog's natural instincts take over. Your dog will use the sense of smell and its nose and paws to move the discs and recover their reward! Offering a multiplicity of hunt & seek experiences, each Disc-O measures approximately 8 5/8"x1 1/8", is made of wood and decorated with charming canine designs.
