Oh, I've been through that with my oldest bully, Lil. Lil is as bully as they come. I fixed her food aggression issue by only giving her a few pieces at a time, reinforcing that the food was mine and mine to share as I pleased. Now anyone, dog or human can take food from her dish. I work with dogs at an animal sanctuary. I rehab them. I am the Alpha at home. She will only eat if I feed her. I usually end up closing myself in the bathroom with her to get her to eat. I shower, while she eats. Then again in the evening while I'm getting ready for bed. This keeps her from bolting with her food. Taping the plate to the floor has helped somewhat. She hasn't lost any weight, so that is good. She marks things occasionally, but she is getting better about that. She has been in rescue since June and two days ago was the first time she barked. I'm pretty sure that she has been beaten for barking, eating and just plain being a dog. For three months she was untouchable, terrified of humans. She is on me like velcro though. Always touching me, always. I actually allow her to sit in my lap while I watch television. This is a bad habit as far as most dogs go, but she is starved for affection and I will do anything to show her she is loved. She wants to please me, I know she will be a great dog once she is more confident around humans.
