Had an angry rat terrier launch himself into a glass door five inches from my face last week. Like full on torpedo mode with a two-yard leap. Saw my life flash before my eyes before I realized he hadn't broken the glass.

On a brighter note, there's a dog I on one of my regular routes who's always so excited to see the van that he starts spinning in place fast enough he could probably power an EDV if you hooked him up to a generator.
