A dog that bites and barks at its owner because of food actually means that it does not fully trust its owner. At this time, the owner can be more bold and hold the food bowl with his hands to give it to the dog, so that the dog knows that the owner will not snatch the food when it is given to him. In this way, he can feed the dog step by step and know that the owner can feed the dog directly with his hands. , this kind of biting will disappear.
