He showed his owner that he was hungry and wanted new servings of food.
Mia Lanett is the owner of the dog Depo that we can see in the video. A year ago, she uploaded a video to YouTube when Depo, with her magic, asked her for more food.
While she was still hungry after eating, she brought him a cup, happily wagging her tail. She offered him an empty plate of food in her hands, to let him know that he was hungry.
Watch the sweet scene of Pitbull when he asks his owner to give him more food. Another proof of how smart our dogs are!
