Oh, and
@Accy cyclist has a point!! If it ain't on a chain... stay in your vehicle
Which reminds me of when I visited a similarly guarded establishment as a sales rep some years ago........
Having parked my car I observed around half a dozen guard dogs, all on chains.
Out of the car, briefcase in hand, I mentally plotted my route to the offices based on the length of chain available to each rabid beast. Easy to see as they were all straining to get at the newly arrived target (me).
I'd successfully negotiated all but the last one, a particularly large and angry wolf-like example. Having got past I glanced back wearing my best smug grin, which seemed to incense the beast into taking another lunge at me, and resting the strength of his chain.
What I didn't know was that a car had parked on his chain, and this last maniac lunge had released another 10 yards of chain I didn't know he had!!!!!
Within seconds I felt his hot breath on my right buttock, and then mercifully he ran out of chain.
I escaped physical injury, but he tore the ar$e outta my suit trousers
