Endal
Endal (13 December 1995 – 13 March 2009) was a male Labrador retriever in Britain whose abilities as a service dog and as an ambassador for service dog charitable work received worldwide news media coverage.
Among other distinctions, Endal was described as "the most decorated dog in the world" (including "Dog of the Millennium" and the PDSA's Gold Medal for Animal Gallantry and Devotion to Duty, the highest award available to an animal) and possibly the most famous assistance dog in the UK,. He was filmed by over 340 film crews from around the world, and had a number of world "firsts" as an assistance dog to his credit.
