My bunny walks around my house and eats the dog food is it bad for her?

I can't confirm that it's really bad for your rabbit, but I don't think it's positive. Think of this: dog food is simply made for dogs, and not rabbits. Dog food 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. You don't want your bunny getting sick.

i'm not a rabbit expert, but if a cat (im a cat expert) would eat dog food, it would eventually go blind... i may be the same for bunnies

keep your dog and bunny in different rooms, or only feed your dog at certain times. dog food is bad

That is very dangerous because it can kill them! You should go and check with the veterinarians!
