I believe a search of the archives (rec.bicycles.*) will reveal at least
one story of some biker getting chewed up. I remember seeing at least
one over the years.
Dogs are a fine motivation for a sprint. Bring on the greyhounds, I say!
(When I'm on my road bike, that is.) I've never had to outrun one on a
hill though. And riding in urban/suburban or very sparsely populated
rural areas, it's been a very long time since I came across a
hostile-seeming dog.
I won't bother with pepper spray - not a justifiable cost/benefit.
Countermeasures for me when I can't get away are the water bottle, then
the frame pump, then anything else that comes to hand, then the bike itself.
I have heard that in extremis, if you grab a pair (presumably, both
front) of the dog's legs and pull apart hard, it will kill the dog.

"We should not march into Baghdad. ... Assigning young soldiers to
a fruitless hunt for a securely entrenched dictator and condemning
them to fight in what would be an unwinnable urban guerilla war, it
could only plunge that part of the world into ever greater
instability." George Bush Sr. in his 1998 book "A World Transformed"
