We don't have any problem at all feeding two, Miss Daisy and Perry. We put their bowls down at the same time and Perry goes to his and Daisy goes to hers and they eat their breakfast or dinner. Neither growls at the other, they don't try to get into each other's bowl. Actually Perry finishes first and just waits and watches Daisy, it has now become a every day occurance for Daisy to leave a few grains of food there for Perry to finish in her bowl. Neither one is possessive of their food and share willingly.
When I give them treats I always give the first to Perry and Daisy waits patiently for her turn. Food has never been a problem in our house, now if you take obedience that's another matter. lol
