I am not really disagreeing with everybody who has posted on here, but I did want to make a couple of points.
First, unless you get really good dog food, a lot of brands list theirmain ingredients as corn. Of course, I still wouldn't give it tobunnies except mabye as a once in a rare while kind of treat.
Second, I know a rabbit's digestive system is not made to eat meat on aregular basis, but they obviously can handle some of it. There is athread on here somewhere about putting a slice of bacon in a doe's cageto help prevent her cannibalising the kits. I have also read somewhere(could be old wives tale, don't quote me on it) that snowshoe haresoften eat carrion. I don't know how much a snowshoe's systmem woulddiffer froma domestic rabbit's, though.
Once again, I am not trying to argue with anyone, just wanted to put in my two cents.
