Wishbone is perhaps the most famous of
Jack Russell Terriers.
Jack Russells should be predominantly white (more than 51%) with black, tan, or
tricolour markings commonly found on the face and at the base of the tail. Jack Russell
Terriers come in three coat types: smooth, broken, and rough. In all cases, the coat
should be dense and not soft, feathery or linty. They have small V-shaped ears that
should fold downward, and strong teeth with a scissor bite.
Due to their compact size, friendly and inquisitive nature, and intelligence, Jack
Russells are popular as pets. Prospective buyers should be aware they are not “lap
dogs”. They are dogs that require training and regular and consistent exercise to
maintain their temperament. Jack Russells that are not trained may exhibit
unmanageable behaviour, including excessive barking, escaping from the yard, or
digging in unwanted places inside and outside the house.
Jack Russell Terriers were first bred by the Reverend John "Jack" Russell, a hunting
enthusiast born in 1795. In 1819, his last year at Oxford, he bought a small white and
tan terrier called Trump from the milkman. After some recent dispute over the
registration of Jack Russell Terriers and Parson Russell Terriers, a group of
enthusiasts registered "Parson Jack Russell" as a trademark. This led to the long-
legged breed being recognized by the AKC under the name "Jack Russell Terrier".
