To protect your dog's food, you only need to let it know that its food will not be touched, or let it know that its food comes from you. If you are aggressive, there will be no food to eat. This process requires parents to be patient. You can put the food on your hands to feed the dog. If the dog roars, don't give it to it.

Tips:

The dog’s food-protecting habits should be corrected as soon as possible to avoid unnecessary trouble for parents in the future, as well as the dog’s habit of barking. If it needs to be controlled, parents should correct it as soon as possible.
