I was pax on an LH 319 last week from MUC to LHR and the "barking" noise as you call it, continued all the way from the quick exit taxi-way to the final stop at the gate. In fact, it was like a bark every two seconds, and lasted for an amazing fifteen minutes in total.
I have heard the noise on several occasions before, but this was the worst and most prolonged I have ever heard.
Real bumpy appproach that day too.
