One word: feisty. These little guys are full of energy and character, and can be alarmingly assertive. In fact, some people find their energy levels to be overwhelming, and the Jack Russell will not do well with a confined living arrangement or a sedate lifestyle. They need to be busy and they need a lot of exercise! They are both a working dog and a companion dog, and are equally adept at killing rats in your barn or beating the crap out of your slipper. They are highly intelligent and will amuse you for hours on end. But you will earn it, as they seem to need an extraordinary amount of human attention and discipline. If you don't train them, they will train you. Jack Russells tend to be aggressive with other dogs and will chase cats and other small animals. They are bold and fearless little guys and are not intimidated by other dogs of any size. The Jack Russell is first and foremost a hunting dog, so is bred to bark, follow a scent, roam around, and dig. Be careful that you don't lose sight of them, as they have been known to go on hunting binges, and can stay "lost," underground, in pursuit of their prey, for days on end. They will need a fenced-in yard to romp around in, because it is nearly impossible for them to get enough exercise on a leash. You will need to be committed to ensuring that the fence is secure, because Jack Russells are escape artists. They can also climb fences. The Jack Russell is an extremely loyal and loving family pet and will do well with gentle children. However, a Jack Russell will not tolerate abuse from anyone, certainly not a child, even if the child doesn't know any better. Jack Russell Terriers will be hopelessly devoted to you, and might even become possessive of you. They do not do well when left alone for extended periods of time. So be prepared for a full-time, high maintenance, best friend!http://www.justdogbreeds.com
