Jasann:Do not try and outrun/bike a dog. You will not win that race unless it is over 10 years old. When a dog is chasing you, it is because of instinct (and a a$$hole owner). Stop your bike, yell STOP as loud as you can and use your bike as a shield. When you stop, the dog figures out pretty quick that you are not prey (the odd Pitbull withstanding). Best advice my vet brother-in-law ever gave me. Fortunately I have not come across too many dogs, but I did 3 times on one ride, including one point when five (yah 5) dogs came running at me full force. They had crossed the road to come after me, but as soon as I stopped and yelled they stopped dead in their tracks. They still barked and growled while I stood there for several minutes waiting for the stupid owners to come out and reign them in (plus I wanted to give them a piece of my mind). No one came, so I slowly walked with bike until they stopped following me and rode off. Scared the crap out of me and pissed me right off though. You can even spray them in the face with your water bottle if they get too close. I never figured I would have enough time or foresight to spray a dog with any type of spray. Plus I would rather do that to the owner, who is the one at fault - dog is just being a dog.
YMMV, but I have found that while riding solo, it is very easy to outrun most dogs. The steps I follow:
1) slow
slightly when approaching the dog (Downshift and be ready to accelerate quickly.)
2) as the dog approaches yell, "No" or "Stop" as loudly and with as much authority as you can muster - Often they will listen to you or be momentarily startled enough to let you safely get by.
3) If the dog is still approaching you, he (Aren't all bad things in life male?) he will have adjusted his intercept angle to your lower speed. At about 3' - 5',
accelerate as fast as you can. Usually the dog having aimed at the wrong point will miss you - once in the front you can get away - few dogs chase for very far.
4) If the dog continues to chase and is about to catch you, unclip the foot on his side, take the foot and kick back as hard as you can.
I have never reached step 4 (at least after using steps 1-3).
Everyone should do what they are most comfortable with, but stopping, especially in the face of multiple dogs is very risky. IF they wer actually going to attack you and they don't stop, you have virtually no defense. You are outnumbered with a bike that is a pretty bad weapon. Stopping and facing them is perceived by most dogs as a challenge and will only serve to antagonize them.
There is a very effective pepper spray that shoots a powerful stream more than 10', even in wind. You can buy it
here at Competitive Cyclist. My problem with such devices is that you have to carry it all the time and if you can't grab and wield if effectively in a second, it is useless. On bikes, we're not like women on the street, who have time to slowly reach into a purse and mentally prepare to fire the darned thing. Most canine encounters last 5 seconds or less.
BTW, the most 'dangerous' dog attack I ever witnessed was on a group ride where a overly friendly lab jumped on one of our riders and nocked her down.
