The Jack Russell is good with children - it enjoy games and playing with toys - but will not tolerate ill-treatment from anyone. This breed also has strong hunting instincts and should not be let loose around smaller animals. It is also fearless - so much so that care must be taken around larger dogs, for the much smaller Jack Russell will not back down. The Jack Russell Terrier has a lively, cheerful temperament, with a strong will. Many Jack Russell terriers have bent legs because of Achondroplasia (a type of dwarfism), but this is considered a fault. The tail is long and is held high, but is usually docked at about five inches. The eyes are almond-shaped and are dark brown or black. The v-shaped ears of the terrier fold forward over a triangular head, tapering to the black nose. (The broken coat is a combination of both long and smooth hair.) Usually this terrier's coat is all white, with reddish black, tan or brown markings on the head and tail.

The Jack Russell Terrier is a small, compact dog with a flexible body, and a small chest - necessary because as a working dog it must be able to get into burrows after its quarry - which comes in three varieties distinguished by its type of coat: smooth, broken or wire-haired.
