Build yourself a Tardis, Amos, and give it a go!

I'm dog-sitting my friend Susie's pack of four red female pooches this week. So far I've got them calmed down at mealtime - they aren't crowding me now because they know there is no food until they sit and I hold their collar. After a suitable period, I point at the bowl and give the command "eat!" that they have mastered perfectly. By the time Susie arrives back home I hope to have them all sitting together in the same room and waiting to eat ONLY their own food when I tell them all "eat." Like I do with my pack of three. That alone will earn me the cash she paid me to feed her dogs.
