Overtoun Bridge is located in Milton, Scotland and is ingloriously famous for deadly leaps of dogs that are walked over the bridge. In the last 50 years about 50 dogs jumped to their deaths from the exact same spot. What makes it even stranger is that all of those leaps occurred on clear, sunny days and the "suicidal" dogs have always been long-nose breeds, such as collies, retrievers or labradors. Those dogs that survive the first leap would recuperate and then jump one more time, locals even have a name for them – "Second Timers".

Some believe that the bridge is haunted and refer a man who threw his own son off the bridge claiming he was an antichrist. And then tried to commit suicide himself. Some believe that the bridge is a "thin place" between the world of living and world of dead and as dogs are believed to be more sensitive to paranormal activities, some claim that the dogs are getting spooked by the spirits on the Overtoun Bridge. The more rational explanation would be the mink population living under the bridge. The dogs, overly excited at the smell of the minks and unable to see over the sides of the bridge, might leap over the side on impulse not realizing that they are on a bridge at all.
