The multiple award winning Planet Dog Orbee Tuff Snoop Toy challenges the brain in fun and stimulating ways. Snoop is translucent and squishy with a deep crevice that conceals the treasure. Filled with treats, dogs will pounce, nudge, nose, and nibble to release the hidden reward. This interactive puzzle toy offers hours of long lasting, brain stimulating entertainment for dogs of any size. For extra credit, insert any 2.5" Orbee Tuff toy (also stuffed with treats) for a double puzzle. Stuff with Planet Dog Treats and enjoy! Snoop is designed to activate a dog's mind and energize its play. Snoop's flexible opening pops out for easy loading and cleaning. Although Snoop is built for durability, it's intended for puzzle play, not chewing, so it is not rated on the durability scale. Snoop is not to be left with dogs unattended. Easy to clean by hand, or on the top rack of the dishwasher.
