Hmmm never done this before so I can't say that I would do it either without looking up the brand more to see if they are %100 alright for a bun. I wouldn't really know because the only treats I have given my bun are apple/applesauce (loves applesauce) banana, raisin, and occasional other fruits. You could try a tiny bit and see if your bun does fine if you think that they are alright.
