The Jack Russell Terriers is a small, principally white-bodied, sturdy and tough, compact and balanced dog, with either a smooth, broken, or rough coat.  He is agile and active, built to go to ground.  His head is moderately broad, with a flat skull, and a well-defined stop, with a muzzle that is slightly shorter than his skull, dark, almond-shaped eyes that are full of life and intelligence, and a black nose.  His ears are button or drop, and very mobile.  His tail is straight and set high.

A small earth dog who can live in an apartment only if given a real job; short or broken coat, a sharp voice, and energy that outruns a still day indoors.

In the 19th century, Reverend John Russell developed a terrier with high stamina for the hunt, and the courage and formation to chase out foxes that had gone to ground, with a tempered aggressiveness that would provide him with the necessary drive to pursue and bolt the fox without causing physical harm to his quarry.  Both the Parson Russell Terrier and the Jack Russell Terrier were developed from this strain.  The Jack Russell Terrier is a smaller, longer-bodied, shorter-legged dog, used almost exclusively to hunt vermin and bolt rabbits.

Temperament

The Jack Russell Terrier is bold and friendly, active and alert, athletic, confident, and notoriously fearless.  Jack Russells are extremely loyal towards their owners, and can be highly territorial.  He tends to be a vocal dog.  He is a high-energy dog, and enjoys a lot of regular activity so, despite his small size, he is not recommended for apartment living.  A well-socialized Jack Russell Terrier can be good with children who have been property educated on how to behave with the dog.

Training

Jack Russells can be stubborn at times, and proper training is recommended.  If not properly and continuously socialized, JRTs can become aggressive towards other animals and, possibly, humans.  Jack Russell Terriers should be taught how to behave with children.

Care and grooming

Jack Russells are high-energy dogs, with a great deal of drive, and require regular exercise.  They are ideally suited to a number of different dog sports, such as flyball or agility training.  The Jack Russell Terrier is a big dog in a little package.  He does not always acknowledge his small size, which can potentially lead to trouble involving larger animals, and care must be taken to avoid these situations.

Shedding

Low to moderate; rough-coated dogs hold more loose hair than smooth coats.

Health

Jack Russell Terriers may develop lens luxation, patellar luxation, and deafness in some lines.  Keep this high-energy terrier lean and give it a job so it does not invent trouble.
