Does anyone have a link where it is proven that there are no extra health benefits over feeding one or the other? My BIL thinks that there are extra health benefits feeding dry rather then wet. Especially when it come to teeth. I feed dry because I like the convenience of it, not because of its supposed ability to clean teeth. By the way I have nothing against wet either. I usually feed it to Jack when we go on a trip because that is the only thing he'll eat when he isn't home. Thanks!!!
