If this senario was a child "playing" to close to the food and the outcome was a bit in that child, you all would say that u cant trust that dog!
The dog have food issues and are very insecure reacting with rage. When Ceasar try to pet the dog in the end she shows no signs that she would strike with that bite. He meets her with the same energy that she is sending out. You are talking about giving her space when she has clealy not earned it yet. If he would have back down at the first rage at the bowl she would have won that round! Imagine that is was a child instead in that situation, would u trust the dog?
