The Treat Challenger, one of GURU's most innovative designs, is perfect for keeping dogs engaged for extended periods while stimulating their natural behaviours. This versatile toy offers dual challenges in one! Simply load kibble or small treats into the ball and cylinder: as the toy moves, it dispenses treats, rewarding your dog's efforts. With two difficulty levels, it ensures prolonged engagement. The Treat Challenger is crafted with Chew Pro, GURU's specially formulated ultra-durable, non-toxic thermoplastic rubber designed for tough chewing and lasting play. It's easy to clean and safe for the dishwasher's top shelf.
