Jack Russell Terriers are incredibly cute, curious and
always ready for a new adventure. But
don’t let their clever antics and friendly appearance deceive you. They are independent minded with energy to
spare and those traits coupled by high intelligence makes these dogs a
challenge to own.
They love having fun and if their activity is restricted or
they do not get enough exercise, your fun loving Jack will turn destructive,
aggressive or highly vocal.

in general, they have strong forelegs, a tail that is set high and carried
slightly over the body, and small triangular ears that drop forward.
Unlike two very similar breeds, the Parson Russell Terrier
and the Russell Terrier, Jacks are somewhat more diverse in appearance. They are bred more for their hunting ability
than their appearance and therefore are not registered with the American Kennel

History of Jack Russell Terriers
The Jack Russel Terrier and the other two breeds, the Parson
Russell and the Russell can all be traced back to one person, the Reverend or
Parson Jack Russell, born in 1795.
First called Fox Terriers, the name was changed in the late
1800s to honor the person most responsible fore creating the new breed, the
Reverend John Russell of Dartmouth, England.
As a young man, Russell had a keen love of fox hunting and developed an
interest in dog breeding.
In the early days, the fox terrier breed did not resemble
today’s Jack Russell Terriers. It was taller,
slender and lanky and the coloring was predominantly black, tan and reddish
brown. Using a dog like this on a fox
hunt was risky because they resembled the foxes they were hunting.
He wanted a great hunting dog with colors that would not
confusing the dog with the prey and started his new breed with a young female
white terrier with dark spots over her eyes, ears and tail.
Using this first dog, “Trump,” along with
other British White Terriers (now extinct) he carefully bred generations of dogs. The British White Terrier was considered a
lap dog because they ranged in size from 10 to 20 pounds and rarely used for
much other than companionship.
was also prone to deafness. After 12
years, Russell was able to create a new line of dogs that were popular with
hunting enthusiasts and British aristocrats.
Russell was known at the time as “the Sporting Parson” and
many of his close friends called him Jack.
After Russell’s death, the dogs remained popular and at times may have
been crossed with Dachshunds, Corgis, and other small terriers which resulted
in major variations in size, shape and type.
At the time, the Kennel Club in England would not accept the breed due
to this variability. Enthusiasts found
their own Jack Russell Terrier Club in 1974.
This group split in 1980 into two camps, one who wanted to
impose a breed standard that would allow them to gain admittance to The Kennel
Club and the other group who preferred the qualities of temperament and working
ability over appearance.
The first group
formed the Parson Jack Russell Terrier Club and was recognized by The Kennel
Club in England in 1989. The American
Kennel Club later accepted the breed in 1997 and placed it in their Terrier
The other group continued as the Jack Russell Terrier club
in both England and the U.S.
Personality of Jack Russell Terriers
If you are considering a Jack Russell Terrier, the first
thing to keep in mind is their history and why they were developed in the first
Farmers and Sportsmen needed a
small hunting dog that could follow a scent, bark to alert the person of their
find, dig down under ground to flush out foxes or other small animals.
To do these jobs, the dog needed to be
fearless, assertive, and tireless. Their
skills included running and chasing, digging, barking, and the show of
Most of these traits that
come naturally to them are not behaviors that the average pet owner wants to
They think of themselves as a big dog in a little body and
will let everyone around know who’s boss if permitted to do so. For these reasons, this little dog may not be
the best choice for a first time dog owner.
Do not think that
the cute little Jack Russell you saw in photos, movies or other types of media
is the type of puppy you will be getting.
(Remember Wishbone from the PBS Children’s
Show or Eddie on the TV Series Frasier?)
These dogs have been trained to do
certain tasks and can perform them on command for short periods of time. Off the set, they are a typical terrier: energetic, independent, and assertive.
Jack Russell Terriers are very loyal and affectionate. They want to be with people all the
time. They are also keenly alert and
will alert you to every new person, animal or thing encroaching on their
As hunters, they are also
barkers, but some of the nuisance barking can be trained out. With all that love that they bestow on their
family, they also come equipped with some behaviors that may not be as
They are extremely intelligent and clever and will continue
to test their limits. Training is
important, not only in puppyhood, but throughout the life span.
They have been known to train their owners
through assertive and even aggressive behaviors. Socialization is very important both with
people and other animals, especially other dogs.
They may bond to one
person in the household and show signs of possessiveness if given the
They may show their dislike
in having to share their favorite human through displays of aggression. Controlling this behavior needs to begin in
puppyhood and maintained throughout the life. To avoid problems.
Energy to Spare
These dogs are very energetic and require a great deal of
Consider them a working dog
that must have a job to do and not a suitable match for a couch potato. They are not going to cuddle on your lap and
watch television all day.
Jack Russell Terriers were bred
to work, whether it was keeping a stable free of rats, digging after quarry or
chasing small prey. If they are to be a
companion dog, they will need daily walks or jogs, playing fetch, or
participating in a dog sport.
This is one small breed that may not be appropriate in an
apartment. The ideal home would be in a
rural or suburban setting with a large securely fenced yard.
A fence is a must and remember that Jack
Russell Terriers love to dig, jump, or even climb, so the fence must prevent all those
forms of escape.
Live in an apartment or condo and have your heart set on a Jack Russell? There is no doubt about it, this breed thrives in places where it can run, chase and just have fun. But there are plenty of examples where they have also done fine living in small apartments.
The trick is to be able to provide the necessary exercise these dogs need. Expect to spend at least an hour a day exercising your Jack Russell Terrier.
Jack Russell Terriers and Other Pets?
These dogs cannot be
trusted around other small pets such as cats, birds, hamsters or simple pocket
pets due to their strong prey drive.
Some breeds can co-habitate with cats if raised together but not
necessarily the Jack Russell Terrier.
If you do have a small pet, protect him/her and do not permit your Jack Russell Terrier to even enter the room where you little pet lives.
Jacks do relatively fine with other dogs.
Children and Jack Russell Terriers?
Jack Russell Terriers do best with older respectful children who have been taught how to handle a dog without teasing, or mistreating them. They are likely to be too much for children
under 6 years of age.
Grooming Jack Russell Terriers
Jack Russell Terriers come in
one of three different coat types:
smooth, broken, and rough. The
type of coat will determine the amount of grooming required.
All coat types will shed! Smooth coats shed the most year
round. The rough coat sheds, but the dead hairs remain within the coat
requiring stripping, brushing, or clipping several times a year. The broken coat is considered to be somewhere
in the middle between the rough and the smooth coat.
The broken coat is very comparable to a smooth coat but has
whiskers around their face and extra hair on their legs or body. It is not soft
or smooth but rather harsh to repel rain, snow and other weather conditions.
The rough coat has the most hair all over the body and it
can be straight or wavy. This coat
requires the most grooming.
The smooth coat and broken coats are the easiest to
maintain. Brush these coats about once a
week to cut down on the amount of shedding in the home. If brushed regularly, frequent bathing is not
normally needed. Dried dirt or mud can
often be removed through brushing but you can also bathe them if they get dirty
(and they will).
The rough coat will need brushing too and stripping several
times a year to remove dead hair.
can be done professionally or you can learn to do it yourself at home. Some owners opt for clipping the coat. For those Jack Russell Terriers that are not involved
in showing, clipping may be a less expensive option.
The hair that results after being clipped is
softer and may even appear lighter in color.
This method does not remove the dead hair, just shortens and makes the
dog look more attractive.
Their nails will need to be trimmed or filed down using a
nail grinder about every two weeks.
It is also recommended that their teeth be brushed several times a week to
prevent tarter from forming.
Health Concerns of Jack Russell Terriers
The breed is considered to be healthy with a life span of
between 11 and 15 years. Many live
longer than that if given proper nutrition and care.
There are some conditions that have been
identified as having a genetic component, some of which may have genetic tests
that can be performed on the parents before breeding.
The list of heritable conditions of this
breed is extensive on the Jack Russell Terrier Club of America website, but
despair. Some breed clubs are more
conscientious at identifying problems with the goal of eradicating them.
Cataracts may occur due to heredity or caused by diabetes,
old age or injury. The lens of the eye
hardens and appears cloudy. Vision is
blurry and can eventually be lost entirely.
Cataracts can be removed and vision restored.
Ectopia Lentis or
Lens Luxation occurs when the lens becomes dislocated. There are two types There are two types, posterior
luxation (where the lens slips to the back of the eye) and anterior luxation
(where the lens slips forward). Anterior luxation also has a high probability
of causing glaucoma which can lead to partial or complete blindness.
Patellar Luxation or
luxating patella is an hereditary problem that affects the knees. The kneecap slips in and out of the groove
where it would normally sit. When it
slips out, the dog may hold the leg up until the kneecap goes back into
place. It can eventually lead to
lameness and arthritis.
This is a neurological disorder
resulting from degeneration of the cerebellum’s cortex. The degeneration can
progress steadily and cause a stagger in the dog’s gait. If your terrier
appears wobbly or disoriented from time to time, this disorder could be the
This malady affects the motor nerves and causes weakness in the
A dog with this condition can have difficulty in rising from a sitting position
and will sway and stagger when walking. So this covers some of the inherited
Jack Russell Terrier health problems.
It must be noted that dogs that are affected with these disorders should not
be bred from.
(vWD) is an inherited bleeding disorder caused by an insufficient vonWillebrand
factor, the blood protein that binds platelets to blood vessels.
This problem is often observed when the dog
bleeds more than normal during estrus or after surgery.
Bleeding can also be observed from the gums,
nose or in urine. Cutting slightly into
the blood vessel of the nails can cause profuse bleeding that requires much
time to clot.
The disease is caused by the ball and socket joint in the hip
degenerating, leading to pain, stiffness and reduced movements.
Being a hunt-driven dog, the Jack
Russell will usually pursue most creatures that it encounters. This includes
