Dobhar-chu (Irish)
The Dobhar-chu 'water dog' or 'water hound'), or King Otter, is a creature of Irish folklore. It resembles both a dog and an otter, though it sometimes is described as half dog, half fish.[citation needed] It lives in water and has fur with protective properties. There are little to no written records of the Dobhar-Chu since its legend has relied heavily on oral storytelling and tradition.
Physical description of the Dobhar-Chu resembles an otter but said to be about five times as large (perhaps 10–15 feet), with white pelt, black ear tips and a black cross on its back. Though, due to the murky waters it is said to reside in, its pelt may be portrayed as darker. A headstone, found in Conwall cemetery in Glenade, County Leitrim, depicts the Dobhar-chu and is related to a tale of an attack on a local woman by the creature.
