Origin and history

The Jack Russell Terrier goes back to the English parson John Jack Russell, who in the 19th century bred an agile, brave terrier for fox hunting. The dog had to work independently, follow the fox into its den and be enduring and fearless.

From this work comes the strong character of the breed: independence, courage, prey drive and a high stimulus threshold when digging and rummaging. The Jack Russell is to this day first and foremost a working terrier, even if it is mostly kept as a companion dog.

Appearance: size, weight and coat

The Jack Russell Terrier is a small but very agile dog with a shoulder height of about 25 to 30 centimetres and a weight of around 5 to 6 kilograms. The body is longer than tall, muscular and supple, made for endurance and agility.

The coat comes in three variants, smooth, rough and broken, mostly white with black or brown markings. All are easy-care, the rough coat is occasionally hand-stripped rather than clipped. Regular brushing suffices, see the guide to coat care.

Temperament and character

The Jack Russell is lively, brave, intelligent and self-confident. It is always on the move, curious and ready to take on any task. These qualities make it an enthusiastic partner for active people, but also a dog that needs leadership and occupation.

Typical is the pronounced prey drive. A Jack Russell follows its nose, likes to dig and can lock onto prey. Without consistent training and exercise, the clever terrier quickly becomes a headstrong, bark-happy daredevil. Good socialisation is important.

Who is the Jack Russell right for?

The Jack Russell suits active, consistent people who enjoy exercise and training and give the dog a task. It is well suited to dog sport, trick training and nose work and gladly accompanies sporty owners on outings. Despite its size, it is not a pure flat and couch dog.

It suits less well calm, inactive people looking for a small, easy companion on the side. As a first dog too it is only recommended with enough time, consistency and activity. An under-challenged Jack Russell guarantees entertainment, mostly of the undesirable kind.

Exercise and training

The Jack Russell needs a lot of movement and above all mental occupation. Long walks alone are not enough for it, it wants to think, work and solve tasks. Search games, trick training and dog sport are ideal to work its alert head appropriately.

Because of the strong prey drive, a reliable recall and a good stop signal are especially important. How to handle this, see the guides on prey drive, recall and dog training. Consistency and humour help in dealing with this clever terrier.

Everyday care

Care is uncomplicated. The smooth and broken coat needs only occasional brushing, the rough coat is additionally hand-stripped now and then to keep its typical texture. Bathing is only done when needed, because the robust terrier loves mud and earth.

Think of nails, teeth, ears and paws as a fixed part of the routine. Because the Jack Russell likes to dig and rummage, a quick check after the walk is worthwhile, for example for ticks or foreign objects in the paws, see paw care.

Health and typical illnesses

The Jack Russell is considered a robust, long-lived breed and often reaches thirteen to sixteen years. Typical of the breed, however, can be patellar luxation as well as certain eye conditions such as lens luxation. In some lines deafness also occurs.

Look for a serious breeder that has the parent animals examined for these points. Because of its fearlessness, the little terrier also underestimates dangers and injures itself more easily, for example in reckless jumps. For health questions, the vet is the right place.

Getting one in Switzerland

A Jack Russell puppy from a serious breeder costs in Switzerland about 1200 to 2000 francs. Choose a breeding operation with health-examined parent animals, good rearing and honest advice that also checks whether this spirited terrier suits your everyday life.

Honestly consider whether you do justice to its need for movement and occupation. Registration in the dog database is mandatory, see the guide on AMICUS. The basic equipment for the start is in the puppy starter kit.

Conclusion: is the Jack Russell right for you?

The Jack Russell Terrier is a small dog with the heart and energy of a big working dog. For active, consistent people who challenge it physically and mentally, it is a loyal, cheerful and entertaining companion with lots of personality.

Anyone who instead expects a calm, undemanding lapdog will be surprised by this self-confident terrier and quickly overwhelmed. As so often: size says nothing about the demands.
