I thought any unit with neodogs reacted normally to tunneling markers... I will doublecheck.
Edit - you're right, it's only pathfinder neodogs that do it. However, that needn't only be models in pathfinder k9 unit, it states that any pathfinder buying the K9 training trait (in the MI army book, this is, rather than pfinder) pays 20 points and gets a pathfinder neodog rather than a mk1 or mk2
