You have stray dogs where you live or what? Cant say cycling has affected my views on dogs.
In a sense it probably made me stronger but I can't say I build a friendship and a mutual sense of confidence with dogs.
She's a 90 lbs Mastiff/St Bernard/Lab cross. It's not like she's worried about being crushed or eaten. She could probably eat me.
Or maybe she doesn't realize she's big. I don't know.
But many bad behaviours are pretty easy to train out of most dogs (eg barking at passer-bys). Dogs are easy to train. Too many lazy owners blame their "nature" or "that's just how they are" as if they can't do anything.
Could probably go for pepper spray nowadays.
So its not cycling then its a stray dog thing :)
