I definitely suggest two food bowls in different rooms for almost anyone. Unless one dog is the very dominant alpha, the other dog will usually steal their food. I remember when we were dog-sitting my sisters Chi, we fed her and Gonzo from different bowls but both in the kitchen. I never really paid attention when they ate, just collected the empty bowls and washed them after 15 minutes. Then we started noticing that Gonzo was getting skinny (he was about 2 years old then), and the Chi was getting chubby .... so we ended up just feeding them their own seperate bowls in their crates, to avoid that.

My sister and brother-in-law, even though it annoys me, feed both of their dogs from one big bowl. They just fill it with Nutro in the morning and either give them a couple cups or 2 raw bones at night. Needless to say, Bentley (the Bulldog) is a big chubber and Mercedes (the BC) is on the skinny side. I doubt that Mercedes completely lets him have all the food though, because she is definitely alpha! She probably just eats a couple cups, then lets Ben have the rest
