Food aggression starts with the fear of losing out.
If your dog has food aggression, be sure you supervise your pet when it's eating. If you have multiple dogs, position the dog bowls in separate areas of the room if that does not work feed the dogs in separate rooms. Also, be sure you understand your dog's body language give your dogs sufficient space during meal time. If you have guests in your home, be sure you feed your dog in another room. It is also a good idea to keep your dog in another room when you have visitors for lunch or dinner for everyone's safety.
If you take your dog to a kennel be sure you give them specific instruction on your dog for his meals and treats including isolating your dog from others doing his meal and treat time.
