The multiple award-winning Orbee-Tuff Snoop 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-inch Orbee-Tuff toy (also stuffed with treats) for a double puzzle.
