My dogo/ab has some food agression, he is in his own separate kennel. He will start eating and another dog will walk into the kennel next to him and he will just do a real low real quiet growl, if the dog doesn't do anything he will go back to eating, if the dog growls back he goes to it
my dogo is still pretty young around 13 mths so I don't know if he is aggressive or just bored. Another thing is if I let him and my other dogs out to run, and a neighbors dog comes over that dog better turn around and go back home in a hurry
