A University of Illinois team fed the same 12 dogs four different foods, four weeks each: a popular kibble, a refrigerated fresh food, and two made from human-grade meat, rice and vegetables. Same dogs, same routine. Only the food changed.
On kibble, the dogs had to eat more just to hold their weight. They produced up to 2.9 times as much waste as on the human-grade foods, a sign that less of the bowl was being used. And their gut bacteria looked different on every diet.
The takeaway was simple: the form food comes in changes how much of it your dog actually gets.
