Lots of stories here. To the OP I say this: do you feel a need and are you comfortable carrying a firearm while biking? It's a personal choice. You'll have to account for your actions. Everyone knows the same rules apply regarding deadly force whether you are riding a bike, driving a car or walking the streets. Were you in fear for your life? You and you alone will have to justify shooting a person. Plain and simple. Shooting a dog might be worse.
