Has anyone heard the urban legend of the black dog? If the black dog passes in front of a trucker, the trucker is supposed to have bad luck in the form of a wreck and probably he or others in the wreck will be killed. I've also heard this as a myth from Ireland. A huge black dog that passes in front of someone who is walking at night brings misfortune and sometimes death. The dog doesn't make any sound except for the clicking of his toenails. Two people may be walking together but only one may see the dog also. Have you ever heard this one?
