I have 4 dishes of kibble and one BIG dish of water out for the dogs at all times. Some of them will stand over the bowl and eat. But Bella will grab a piece or two, run to the living room, drop it on the floor, then eat it and run back for more. It must be the way she keeps her girlish figure: she runs off whatever she eats!
I have theorized that pups that eat off the floor were smaller than their siblings. The bigger pups crowded around the dish at mealtime and ate like little demons, pushing food here and there. The smaller pups got to eat the "overflow", what got pushed out of the dish. So they're more comfortable eating off the floor than from a dish ... something they didn't get much experience with

Me? I've always been kinda permissive: as long as they ate, I didn't much care how they did it.
