Canine Food Aggressions
It is not unusual for a dog to guard its food by growling when another dog approaches. It is saying, “This is my food! Get back”. The approaching dog should respectfully retreat. Communication over. You may avoid this by feeding each dog in its own dish in its own location. (Of course as leader of your pack, you should not be growled at if you approach its dish) If the intensity and frequency increases then you may be headed for the next category in which the dog bites hard and injure dogs in its own pack.
