This is a fun dog toy that can be filled with either liquid or solid food. Simply fill the toy with food and then let your dog play with it. Eating while playing effectively slows down their eating pace, promoting a healthier digestive system and making mealtime more enjoyable. Additionally, you can customize your dog's nutrition by filling the toy with dog food and adding some water and then freeze it for 4-6 hours. This helps further slow down their eating pace and provides entertainment when you're away. The toy has an unpredictable rolling direction, attracting your dog to chase, chew, roll, carry, and catch it, keeping them busy at all times and engaged and mentally stimulated, effectively releasing their excess energy.
