Also known as: Black Dog, Dog-Fiend, the Werewolf, Vanishing Dog

The Snarly Yow is a local phantom Black Dog found in both Maryland and West Virginia folklore in the United States. Unlike the Black Dog of British folklore, the Snarly Yow is sometimes described not as black, but as a white, headless dog dragging a chain from its neck. It has a red mouth, glowing eyes and over-sized paws and known to be very intimidating in appearance. A few sightings will claim the beast stands on its hind legs or that it can change its size to that of a small pony.

Maryland Legend

The Snarly Yow is often found at a pass where the old National road crosses a brook and canyon. The first stories and sightings of the Snarly Yow date to 1790 where an Inn was built close by in Maryland. There are many stories of people encountering the Snarly Yow either while walking, driving, riding horseback where the phantom dog appears, follows along or chases after the car. Or just simply appears and vanishes. Variations to the stories will tell how the horse becomes spooked and throws the rider, how others have thrown sticks and rocks at the beast or even fired at with a firearm, only to have the objects pass through it. Every story ends with the Snarly Yow just vanishing before their eyes.

“South Mountain Magic” – A book written by Madeleine Vinton Dahlgren in 1882, collected many of these encounters. Dahlgren, a wealthy widow had a summer home on South Mountain where she made it her mission to collect local legends. The most striking feature of her book is that many of the stories about the Snarly Yow are all first-hand accounts ranging from a preacher, to a farmer’s wife and to a mountain man who have all had encounters with the beast.

Dahlgren’s book describes the Snarly Yow as an intimidating and imposing wolf-like creature that could change its size. A dark, black shadowy beast, it would mostly just block the path of any travelers coming through.

“Snarleyyow: or, the Dog-Fiend” – Is a high seas adventure novel written in 1837 by the British Naval Officer Frederick Maryatt. His book clearly features a similar large black dog known for being intimidating and formidable.

Civil War – The Civil War saw many battles, one of which, Battle of Antietam near Sharpsburg, Maryland, that claimed over some 22,000 lives in one day of fighting. A number of ghost stories rose up surrounding this battle and the Snarly Yow is just one of many such phantoms to make their appearance.

A plaque located by the road near Boonsboro, MD for a local battle that happened at South Mountain reads:

 “Beware of the “Snarly Yow.” Legend has it that the shadow of a black dog used to prowl the heights of South Mountain. One night, a huntsman, famous as a sure shot, encountered the beast. He aimed and fired his rifle. The shot went right through the animal with no effect. He fired again and again, each shot passing through the shadowy beast. Finally overcome with dread, the huntsman fled.”

Turner’s Gap – A location near South Mountain, it is the sight of a Civil War battle known as “The Midnight Battle.” The Snarly Yow is known to appear here.

20^th & 21^st Century Encounters – Many of these stories revolve around the Snarly Yow, like any dog, either blocking the road or chasing cars that drive along National Road (Route 40). Drivers will stop, thinking they have hit the apparent dog, only to get out, find nothing is there and when they turn to get back in their vehicle, the Snarly Yow appears, baring its teeth at them before disappearing.

West Virginia Legend

The Snarly Yow is believed to roam the mountains and hills near Harpers Ferry, part of West Virginia’s Eastern Panhandle. The stories of the Snarly Yow here begin in the 1700’s when the first Germans settled in the Potomac Valley. The name comes from the Germanic words to describe this creature’s howls and wails.

Civil War – The Civil War saw many battles and the town of Harpers Ferry was greatly contested by both sides, often changing hands. The Snarly Yow, just like in Maryland, is just one of many such phantoms to make their appearance.

Most of the stories regarding the Snarly Yow tell how people have claimed to shot at or run over the creature. Then, either believing the apparent dog to be killed or injured, they discover, when looking back, that the creature standing nearby. A few people report having seen the Snarly Yow standing on it’s hind legs like a human. This ghost hound will appear out of thin air, alter its size and just as quickly as it appeared, vanish. Most often the Snarly Yow will appear along roadsides or in the middle of the road.

Other Areas

 Stories of the Snarly Yow have also extended its range to the Blue Ridge Mountains of Georgia and even Hillsboro, Virginia.

British Black Dog

In Europe, particularly in the UK for England and Scotland, there a lot of folklore regarding Black Dogs and several different such individual Black Dogs. Sightings of these dogs have been going on for over 400 years. In British folklore, seeing a Black Dog is often an omen of death. These Black Dogs are often found out in the wilderness along old roads, bridges and pathways. Sometimes the Black Dog is in association with a nearby graveyard that it protects. Like the Snarly Yow, the British Black Dogs have glowing red eyes, are large and able to change their size; suddenly appearing and vanishing. Most Black Dogs encountered in British folklore might protect a family or warn an individual of coming death; with some cases outright heralding it. While some Black Dogs are more vicious than others, it is only if they come into physical contact with someone that they attack, can the Black Dog cause harm in the way of paralysis, death and serious wounds.

The Snarly Yow differs from the British Black Dogs in that it is not an omen of death, it just seems to have a penchant for appearing, blocking the path of travelers as it scares them and then just vanishes. Other than getting startling and scaring people, the Snarly Yow hasn’t ever really hurt anyone, unless you count the time a rider got thrown from their spooked horse and broke their collar bone.
