English Water Spaniel

The English Water Spaniel is a breed of dog that has been extinct since the first part of the 20th century, with the last specimen seen in the 1930s. It was best known for its use in hunting waterfowl and for being able to dive as well as a duck. It is described as similar to a Collie or to a cross between a Poodle and a Springer Spaniel with curly fur and typically in a white and liver/tan pattern.
Pre-dating the Irish Water Spaniel and thought to have been referred to by Shakespeare in Macbeth, it is believed to have genetically influenced several modern breeds of dog, including the American Water Spaniel, Curly Coated Retriever and the modern variety of Field Spaniel. It is unknown if the breed was involved in the creation of the Irish Water Spaniel.
