There is a bridge in Scotland famous for dog suicides..!! Since 1950, over 50 dogs have leaped from overtoun bridge and kill themselves at the rate of about one dog a month...!!
Dogs leap over the bridge parapet fall 50 feet (15 m) below. Some dogs that survived this drop, and were then taken back to the bridge, have also jumped again. The only linking factors for this unexplained event is that dogs mostly jump from the same side of the bridge, in clear weather, and they are breeds with long snouts.
