The pastor, who runs a local centre for women in crisis, moved into the nearby Overtoun House with his wife almost 20 years ago and said that he had seen several dogs suddenly dive off the bridge.Despite Scotland being the “kind of a place where there is a lot of the supernatural” it is the smell of small mammals scurrying in the gorge which sends dogs into a frenzy and leads them to break off their leash.However Paul Owens, a religion and philosophy teacher, disagrees with the theory. Mr Owens has researched the dog deaths for 11 years and has even written a book about mystery, “The Baron of Rainbow Bridge: Overtoun’s Death Leaping Dog Mystery Unravelled”.He told the newspaper that a ghost “is behind all of this”. He even went as far as to identify it as, ‘The White Lady of Overtoun’ – the often-sighted ghost of a local woman who died in 1908 and never got over the death of her husband.In his book he also argued against the findings of David Sands, an animal behaviourist, who said that it was dogs’ limited perspective as well as a possible ‘scent theory’ that lured dogs to jump – yet even he admitted that the bridge had a “strange feeling”. For decades it has stupefied locals. One moment, they are out enjoying a walk. The next they are hurling themselves off a 50 foot bridge and plunging to their deaths on the jagged rocks in the gorge below.Now a pastor claims to have solved the mystery as to why hundreds of dogs have reportedly committed suicide by falling off a rural bridge: the scent of small mammals.Since the 1950s, Overtoun Bridge in Dumbarton, Scotland, has played host to a bizarre trend of canines leaping off it. Befuddled and grieving residents of the town, which is north west of Glasgow, have blamed everything from witchcraft to paranormal activity.However they remain united in their insistence that the historic stone structure is now known as the ‘dog suicide bridge’. There is even a sign telling walkers to keep dogs on the lead.Yet decades after the first recorded dog death, a Texan pastor living in a nearby manor believes he has the answer to expunge such supernatural theories.“The dogs catch the scent of mink, pine martens or some other mammal and then they will jump up on the wall of the bridge,” Bob Hill told The New York Times. “And because it’s tapered, they will just topple over.” Want the best of The Telegraph direct to your email and WhatsApp?
