i don't really think dry makes any difference to teeth unless they are eaten by very small dogs or a large dog eats a huge biscuit.
just a little question to put it into perspective - do your teeth feel clean after eating biscuits?
a raw chicken wing once or twice a week works wonders - aslong as they chew it.
good complete tinned is natures menu (although is expernsive).
another option is to soak the dry and gradually put less water in so it gradually becomes harder over a couple of weeks until you no longer need to put water in.
if they don't eat it soaked add a little tinned food - mix very well and reduce that over time as well
hope this helps Anna
