I can't Bestätigen that it's really bad for your rabbit, but I don't think it's positive. Think of this: dog Essen is simply made for dogs, and not rabbits. Dog Essen contains meat (think chicken, beef, pork etc), and rabbits aren't supposed to eat meat, they're herbivores. Please don't let your bunny do this anymore. When he's getting his exercise, just put the dog bowl up on the counter and make sure there's no little peices on the floor either. Du don't want your bunny getting sick.
