The Kong Wobbler is a traditionally Kong-shaped food and treat dispenser. Constructed of FDA food-approved, high-strength, plastic polymer, the Wobbler is a toy that sits on the line between fun and mealtime. This toy is designed to stand upright when placed on a flat surface, but to move about unpredictably as soon as your dog knocks it over. The top of the Wobbler unscrews, making it easy to fill with food or treats, which are dispensed through a hole as your dog spins and rolls the toy around. Keeping this toy clean is very easy, as it is dishwasher safe.
