The Jack Russell Terrier is a perky, merry, devoted, and loving dog. Spirited and obedient, yet absolutely

fearless. Careful and amusing, he enjoys games and playing with toys. Friendly and generally kind to children

who have been taught not to tease or strike the dog. They are intelligent, yet willful and determined. They can

be slightly difficult to train and need a firm, experienced trainer. The Jack Russell can be aggressive with other

dogs if not well trained and socialized. Some have killed or been killed in dog fights. Early socialization can

help substantially moderate this trait. They have strong hunting instincts (stronger than your average terrier)

and should not be trusted with other small animals. They like to chase and explore. Be careful not to let them

off the lead unless they are very well-trained. Jack Russells like to bark and dig. They tend to get restless and

destructive if not kept fruitfully occupied and well exercised. Jack Russells climb, which means they can climb

over a fence, they also jump. A Jack that stands 12 inches high can easily jump five feet. JRTs are not the

breed for a inexperienced dog owner. This is a BIG dog in a little dogs body. The owner needs to be as strong

-willed as they are, or this little guy will take over. With the right owner this little dog can really excel, but is

not recommended for those who have not had prior experience with terriers. The Jack Russell Terrier must

present a lively, active and alert appearance. It should impress with its fearless and happy disposition. It should

be remembered that the Jack Russell is a working terrier and should retain these instincts. Nervousness,

cowardice or over-aggressiveness should be discouraged and it should always appear confident.
