Dognip

Last night my son and I were watching our Bichon rolling around on the floor, rubbing his face on the carpet, tossing his dog toys and generally just being a goof. This got him thinking about how catnip makes cats go crazy and, apparently, makes them high. He then asked me if there is an equivalent herb, food or substance for dogs.
So, to all of you poochy experts, is there such a thing as dognip?
