Firstly, put the food directly on your hands every time you feed, so as to get more of the dog's attention. Secondly, put the food on the ground and prevent the dog from eating it. If the dog behaves well, you can give it snacks. Reward, in most cases, as long as repeated training is carried out, the dog will not eat randomly. When taking the dog out, you should pay attention to wearing a leash to prevent the dog from getting lost.
