Blue Dog of Rose Hill, Frederick
It could be just another variant of an urban legend or a wholly separate story, but the city Frederick (Frederick County) has its own Blue Dog of Rose Hill. The grounds of Rose Hill Manor off Route 355 in the northern part of the city are also haunted by a phantom blue dog. This blue dog was the pet of a previous owner of the manor. The owner had buried treasure “six feet from the old oak tree” on the property. The ghostly dog appears at midnight, wanders the grounds, and vanishes as mysteriously as it appeared. Now-deceased Maryland researcher Mark Chorvinsky of Strange Magazine investigated the tales of the Frederick Blue Dog.
