There are varying degrees of defense against dogs.
1- Shout "NO!" as loud and authoritatively as you can. That works more than
half the time against most dogs that consider chasing you just good sport.
2- Get away from their territory as fast as you can.
3- A water bottle squirt sometimes startles them.
If they're waiting for you in the road and all you can see are teeth then
you in a heap o' trouble. In those situations, I've turned around, slowly,
not staring at the dog, and rode away.
"Halt" works pretty well, and I've used it at times. It's range is about 8
I bought a "DAZER", from Heathkit. Its a small ultrasonic sound generator
that you point at the dog. My wife and I were tandeming on a back road and
used it on a mildly aggressive German Shephard. It seemed to cause the dog
to back off.
By far, without a doubt, hands down winner, is a squirt bottle full of
reagent grade ammonia, fresh out of the jug. The kind that fumes when you
remove the cap. When I lived in Illinois I had a big, mean dog that put its
cross-hairs on my leg whenever I went by. After talking to the owner
(redneck), I bought a handlebar mount for a water bottle and loaded it with
a lab squirt bottle of the above mentioned fluid. Just as the dog came
alongside, I squirted him on his nose, eyes and mouth. The dog stopped dead
in his tracks and started to roll around in the street. Although I
continued to see that dog on my way to and from work, he never bothered me
Finally, you can usually intimidate the most aggressive dog if there are
more than one of you. Stopping, *and moving towards it will often cause it
to back off*. ( But not always ). My bottom line is to always *run* routes
that I'm not familiar with, with someone else.

Gordon Pirie's book "Running Fast and Injury Free" which can be found via
http://www.gordonpirie.com . Pirie is a proponent of fore-foot striking.
All I can say is Pirie works for me. As a novice, having a pretty
straightforward book on technique to read, one that is uncomplicated by
jargon, is very useful. For me, even before a novice puts on his/her
running shoes for the first time, it is worth reading this book (its *very*
short). Not all of it is relevant to the recreational runner, but the bits
that are are very obvious and accessible.
