600 dogs had 'mysteriously' jumped off bridge in Scotland 
About 600 dogs are known to have jumped off Scotland's Overtoun Bridge, with about 50 dogs losing their lives in the past 50 years. Some believe that the bridge is haunted by a man who threw his baby off the bridge. According to research, the bridge causes 'sensory overload' and confuses the dog's sight and hearing, causing it to jump.
