I have 2 boxers, a 6 yr old mom, Kira, and her 4 yr old son Duke, which is twice her size. I keep their food out all the time, I don't want them gulping and risking bloat. I keep dry food in 2 bowls...have to have 2. Kira will see Duke eating, and chase him away from the bowl...and he just goes over to the one she just left and starts eating. They switch bowls 2-3 times while eating. The thing is..you have to have some food in both bowls all the time. They will flip over the empty bowl (not small bowls either) if one is empty. Duke is usually the one to do this, with a look on his face as if to say "You know the rules".
