The Province of Ontario is considering a ban on pit bulls (the dogs)
after several rather nasty attacks by pit bulls in the last year. The
Ottawa Citizen had a letter to the editor supporting such a ban

The letter writer was commuting to work when he encountered two
muzzled pitbulls and their (presumed) owner on the sidewalk. He
stopped to let the trio go by but as they passed one of the dogs
managed to stretch its muzzle enough to bite the rider in the arm.
Dogs and person ran off.

Of course, what the rider did not seem to notice that he was already
breaking a municipal bylaw by riding on the sidewalk. I have seen and
heard of many reasons for not riding on the sidewalk but this is a new
one to me.
