I totally agree with Gabrielle...your dog needs to learn that you control the food and not her. I feed 3 dogs together here and not one will ever go to the wrong bowl. Make her sit before releasing her to go to her bowl, sit, stand down, doesn't really matter as long as she learns you are the boss. I would feed the dogs only when you are around so you can keep your eyes on the others and make sure they get their share. If you have to feed Roxy inher crate until she gets the message. The growling should not be allowed, it will turn into a full blown bite.
