Famous Jack Russells

The Jack Russells intelligence and charisma have led them to be quite well known over the years. From great explorers to starring roles here’s a roundup of some of the most memorable JR’s.

Nipper the perhaps the first famous Jack Russell, born in 1884. He was the inspiration for the painting Dog looking at and listening to a Phonograph, later renamed to His Master’s Voice. But it’s probably better known for it’s later use as the HMV logo.

A Jack Russell named Bothy made history in 1982 as part of the Transglobe Expedition. Owned by explorer Ranulph Fiennes, he became the first dog to travel to both the north and south poles. An impressive ‘tale’.

Father and son team Moose and Enzo played Eddie in the long-running sitcom Fraser. Perhaps best known for the famous Jack-Russell-stares that unnerve the radio psychiatrist. They received more fan mail than any other character on the show.

In the Mask starring Jim Carey the real star was Max. The Jack Russell Terrier played the role of Milo (after which our very own JR is named!) who is one of Stanley Ipkiss’s only friends in the 1994 U.S film.
