A dog on the streets of Canada was in such a poor state that those who saw him might have passed by thinking it was rubbish. His legs and body were barely even recognizable, and his scared eyes peaked out above a dreadlock-cloaked snout.

He was caked in a thick layer of dirt and matted hair that nearly doubled his size, according to Quebec Hebdo (translated via Google Translate).
