Oreo my mix who is 5 has food aggression issues with other dogs. Now this is a recent development just over the past 2 years. When we had cinnamon our mini doxie they shared a bowl and everything. But when we went home to El Paso and Oreo had to stay outside with my brothers dog Blue, a cocker spaniel/ rotty ( don't ask me how it just happened) she started having food issues. But only with dogs. If I or my kids go near her bowl she will turn away and wait for us to leave. I have put my hand in her bowl taken it away from her and still no aggression. But if any dog goes near her bowl, treat, or what ever she is eating she starts to get aggressive. She even bit cinnamon on the head once over a bone. I now give treats seperatly and always give Oreo her's first since she is the lead dog. But is there any thing that can be done about this or is this something that I just have to deal with and feed my dogs seperatly?
