The dog slow food tray is large enough to let the dog play and train alone when the owner is not at home. It can be placed in most on a flat surface, such as the floor of a room, living room and so on. ?The Scientific Slow Food Function?Each barn can only hold a small amount of food, and the dog has to open the lid to get food. When he finishes eating, he has to press the top button again to refill the barn. This design can effectively slow down the eating pace of the dog and correct the bad habit of eating too fast. It increases the time and difficulty for dogs to get food, avoids the indigestion, reduces gastrointestinal pressure, and makes them healthier. ?Train Your Dog to Use This Toy?The dog needs to go through two steps to get the food. First, he needs to press the transparent button at the top of the toy. The kibbles will fall into the six barns around the toy, then the dog has to open the lids of different barns with his paw or nose to get the food. Unlike traditional educational toys, our toys allow dogs to eat their own food after two steps. ?Improve your dog's IQ?CAROZEN dog puzzle toy designed to improve your dog's IQ. Unlike traditional entertainment dog toys, this toy allows your dog to become smarter through his initiative while receiving food rewards. Train him to use the brain and promote brain development.
