Have you ever stood close to your dog and watched them as they ate. Some untrained dogs may growl or snap at you, while other dogs may refuse to eat until you leave or will take their food to another location, probably their cage. Why? Because it’s uncomfortable and they feel like you’re intruding on their meal time or may even think you’re trying to steal their food from them. So if a dog realizes there’s something why can’t a human.
A well trained dog will understand that your food is your food and his food is his food
