I don't think cuttlebones are "recommended" for dogs. However, it is just the bone part of the cuttle fish and is composed of aragonite (i.e calcium carbonate), which is the same composition as egg shells!
So the cuttlebones are not "toxic" to dogs; however, they can pose a choking risk if your dog gulps them down without chewing them up properly (i.e they may get stuck in the oesophagus or stomach and cause a foreign body, which may be quite expensive to fix!). Having said this, MOST dog foods have this risk associated with them (cooked and uncooked bones can BOTH lodge in the digestive tract!).
So I'd stay away from them if possible... but I'm sure the odd one or two won't hurt! :)
