I hesitate to argue with Bose but you can wheel a Terrier. But much like the argument with the Hornet Moth there is little point in doing it. To get a truly gentle touchdown which you need, usually means messing about in the flare often using throttle - which does eat runway.
I only ever did it when playing around just to prove I could! Or in a serious (but steady) crosswind. If you could hold it straight on the mains against the wind then it was likely you could stay on the runway using the one and a half good brake applications a Terrier will give you!
