Legendary dogs

crime novel by Arthur Conan Doyle

The Dobhar-chú (; ), or King otter, is a creature of Irish and Scottish folklore. It resembles both a dog and an otter, though it sometimes is described as half dog, half fish. It lives in water and has fur with protective properties. There are little to no written records of the Dobhar-Chú since its legend has relied heavily on oral storytelling and tradition.
