The Overtoun Bridge, Scotland. On the road to to Overtoun House near Dumbarton, Scotland, is a bridge that invites suicide, especially in dogs. Since the 1950’s at least one dog per year has jumped off the bridge, onto the waterfalls below. Several animal behaviourists and scientists have tried to figure out a reason for it, but everyone is stumped. Whenever someone takes their dog on the bridge, they will try to kill themselves. There’s signs everywhere to make sure you keep your dog on a leash, but some dogs are so persistent in jumping that they break away. Now that’s sad; poor doggos.
