Dog guarding food is an instinct of dogs. When feeding, owners can feed it with their hands and gently stroke the dog's hair with the other hand to help relieve the dog's nervousness. Do not let the dog eat because of the dog's nervousness. Beating and scolding the dog while protecting the food will cause a psychological shadow on the dog. As long as the owner patiently guides the dog many times, the dog will put down its guard and will not behave in a way to protect the food.
