Situated within a pretty, historic estate in Dumbarton, Scotland, Overtoun Bridge is a charming 19th century crossing over a small gorge. It should be unremarkable and relatively unknown, except for its ornate beauty. However, it has become infamous for a macabre phenomenon. Ever since the 1960s, dogs have been reported to be jumping off this bridge, many to their deaths. It has thus become known as the dog suicide bridge.

Overtoun Bridge is a 19th century bridge in an ornate Scots Baronial style. It forms part of the Overtoun Estate in Dumbarton, Scotland, its views and surrounding wildlife making it a popular walking spot. However, ever since the 1960s, it has become known for a disturbing trend. That of dogs jumping off the bridge. Possibly hundreds of them. Many to their deaths. So much so, it has earned the moniker of the dog suicide bridge.

For decades, dog walkers have reported instances of dogs jumping off Overtoun Bridge. According to anecdotes, dogs very purposefully run and leap from the side. Many descriptions include the canines behaving strangely immediately beforehand, sometimes appearing to stare at a particular spot or becoming frenzied.

Estimates vary wildly as to the number of dogs who have jumped, some saying 300, others 600. What is more widely accepted is the figure of roughly 50 deaths of dogs resulting from these incidents. Not surprising given that it is a fifty-foot fall, at the bottom of which lies a rocky gorge. Fortunately however, many do survive the drop.

Local lore has it that it is the spectre of the White Lady of Overtoun lures the dogs over the bridge’s edge.

The lady in question is Lady Overtoun, the troubled widow of Baron John White, whose ghost is said to haunt the estate.

Attempts have been made to provide more earthly explanations for the so-called dog suicide bridge. The Scottish Society for the Prevention of Cruelty to Animals was called in to investigate, but couldn’t identify a specific cause.

Most animal experts point out that dogs, like other animals, have no concept of suicide. Instead, they attribute the jumps to a combination of factors. The most likely of these is canines being overwhelmed by their natural instincts.

One animal behaviourist, David Sands, noted that most of the dogs who jumped were of a long nosed variety. The heightened sense of smell of such breeds – already very strong in dogs – led him to posit that they were responding to the smells of wild animals below. Of the wildlife in the area, minks are thought a likely source, their scent being particularly potent. He coupled that with the lower viewpoint of dogs, possibly making them misjudge the drop.

The mystery of Scotland’s Overtoun Bridge and its deadly connection with dogs continues to baffle scientists and concern pet owners. And, while the possible explanations offered by experts have potentially explained this bizarre phenomenon, many will continue to blame the ghostly White Lady of Overtoun.
