The Water Hound of Glenade
The Dobhar-chú is half dog, half fish. It has a dog’s head, a dog’s hunting instincts, and a body that ends in a fish’s tail. It lives in the lakes of Connacht and Leitrim, attacks at the water’s edge, and can chase a person across dry land as well as through water. It is an active predator, not a harbinger or a trickster.
On the 22nd of September 1722, Grace Connolly was washing clothes at the shore of Glenade Lough in County Leitrim when the Dobhar-chú killed her. Her husband Terence McGloinn heard her scream, ran to the lough, and found her dead with the creature lying across her body. He stabbed it. As it died, it whistled. The whistle called a second Dobhar-chú out of the lake. The second creature came after McGloinn and his companion on horseback, pursuing them across the countryside until they reached Cashelgarron, where they stopped and killed it by driving a blade through its heart.
The gravestone marking Grace Connolly’s grave stands in Conwall Cemetery in County Leitrim. It shows a carved image of the Dobhar-chú — long body, dog’s head, fish’s tail — and the scene of the attack. It is still there. It is one of the only physical records of a specific Irish supernatural creature encounter that survives.
The death-whistle is the most important thing to know about the Dobhar-chú. Killing the first one does not end the threat. It summons the second one. The first kill is not safety. It is the beginning of the second problem.
