Jacks, Jack Russells... call them what you will. They are 'terrier-rific' by
any name. Smart, energetic and always eager to play or work, they make great
companions... for anyone with the energy to keep up with them.
Jacks are generally on the small side, averaging about 14 pounds with a
chest size roughly 12-14 inches around. Like most terriers, they were
originally bred to chase out small game. They come in different sub-breeds,
with tri-colored brown, black and white coats that are either smooth, broken
or rough. All can live as long as 15 years or more.
The natural tail is straight and held high, one reason they're often
docked to about five inches in length. Then they wag to and fro like little
metronomes. That 'musical beat' tends to be pretty rapid, though, as a Jack
Russell will chase a cat, squirrel or anything else around in a flash. As a
result, it's best to leash them when they're not in a safe, enclosed area,
such as the backyard.
They enjoy attention, though, so it's not a good idea to leave them out
there on their own for long periods. Like all terriers, they enjoy digging and
will quickly destroy any manicured lawn or garden. That instinct can be
channeled but not eliminated, and only partly curbed.
Obedience Training for Your Jack Russell
Bred for centuries to ferret out rabbits, foxes and other small animals,
a terrier wants to go down a hole, even if they have to widen it a bit. Jacks
are no exception. That same energy level can get them into trouble in other
ways. Since, like most terriers, they're basically fearless, they will fight
with dogs much larger than themselves. The results are not always in their
favor. Because of their staunch attitude, some larger breeds will back off.
Those that don't will often get the better of a Jack Russell who has taken careless stock of a situation and picked on the wrong big dog.
But that intrepid attitude also makes them loyal and very protective of
their 'terrier-tory'. While they can be socialized to include other pets in
the home, they greet strangers with a wary eye and often a harsh bark. They're
not overly inclined to bite, though, and quickly warm up to people to whom
they're introduced by the 'alpha' of the pack (that's you).
However, when introducing them to young children or those who are
nervous about dogs in general, it's best to proceed with caution. A chest
halter and a firm grip can make the process safe for all participants. Getting
down to their level reduces jumping, but take care not to get your face close
to a Jack that isn't well restrained. Bites are unusual, but snapping can
still be upsetting.
Like all terriers, they can be trained, but remember that they operate
most of the time from instinct, which is the drum that beats loudest in their
ears despite your best efforts. Unlike, say, a German Shepherd or Golden
Retriever, they remain independent and strong-willed even with the best of
training. Still, the effort is worthwhile. Neglect training and the
alternative is uncomfortably close to a wild animal.
