What foods are dogs allergic to?

Dogs don't really have Allergies but if you count death as one do not give a dog raisons,grapes,chocolate,or nuts they are dog poison and will kill them if a large dog eats only alittle nothing will happen but even a little bit will kill a small dog but that doesn't mean you can give that to large dogs and bones are bad the may be smooth on the out side but dogs chew their food of you break a bone in half it will be as sharp as a knife and will cut the dogs stomach or neck and will usually kill them immediately make sure dogs don't chew cans too they are just like bones but milk bones and the ones at pet stores are jusr fine.
