+1. I fractured my pelvis in three places (including a doozy from the outside of my ilium to my sacrum requiring a 6" plate and 4 pins to put back together) when two dogs ran out at me from a 90 degree angle. They did not hit my bike because I sped up out of instinct before they got to me, but my DH (who was a little ways in front of me -- a few feet at least) slowed down, and I plowed right into his rear wheel at speed. Scared the dogs right away, but by then the damage was done.
So...if you're going to try to outrun dogs, make absolutely sure there is no one in front of you who might react differently.
I should also mention that I was reaching for my Halt (pepper spray) right before I crashed -- it was right there in a handlebar holster but couldn't keep me safe in this instance!
