Jack Russell Terrier
Jack Russell Terrier bred in the UK. Mr. Jack Russell lived in Devonshire in England, who was fond of hunting with hounds and burrows of dogs. Having become a professional in this field, Mr. Russell participated in exhibitions as an expert on terriers and was one of the first founders of the famous English Club of Dog Breeding. In the second half of the 19th century, due to the development of pastoralism, traditional horse hunting for deer and roe deer became less common in England; burrowing of foxes, hunting of wild boars and rabbits became more popular. For this, dogs of short stature and short hair were needed, which could run no worse than hounds – quickly and for a long time.
In this regard, Jack Russell set out to bring a normal dog with the qualities of a hound, medium-sized, but strong and fearless. The basis of the breed was wire-haired Fox Terriers, which were crossed with Old English Terriers, Bull End Terriers, Sealyche Terriers and Lakeland Terriers. To obtain a new breed, individuals with pronounced working qualities were left, while the exterior of the dogs was not paid much attention.
Currently, Jack Russell Terriers, due to their small size and sociable character, have acquired the appointment of companion dogs. In the UK, this breed is very popular, although it was registered only in 1990. The breed standards were approved by the FCI in 1997. The largest jack Russell population is registered in Australia.
Jack Russell Terriers belong to the group of small breeds of dogs. The weight of an adult dog is 6–7 kg. The height at the withers of a male is up to 35 cm, and that of a female is 28–34 cm.
The mating with various terriers and Old English bulldogs led to the appearance of several varieties of jack Russell terriers. They can be of dry physique and elongated limbs. Other dogs of this breed are stocky with shortened limbs (as a result of crossbreeding with Old English Bulldogs).
In general, Jack Russell Terriers can be called stocky – at the same time, these low, strong dogs with an elongated body and relatively short paws often amaze with their activity. Even in an active game, jack russels demonstrate enviable stability – this is facilitated by the location of strong paws at a right angle to the body. In addition, many future owners of dogs of this breed are attracted by cute small ears with hanging tips. Active people are attracted by a developed dentition and a powerful muscular neck – with adult dogs of this breed you can have fun playing with long ropes on which jack russels hang with pleasure. These dogs are also distinguished by a high-set muscular tail, which indicates the willingness of the dog to work.
Jack Russell is a shorthair dog. The coat is stiff, short, hair straight or with a kink, fits tightly on each other, on the muzzle and limbs of the hair is very short.
When breeding this breed, preference was given to white dogs with small spots, since when hunting such a dog was easy to distinguish from the beast and not injure.
The main color of the coat is white, with red medium-sized spots of various shades, more often on the head and in the area of the root of the tail, black spots are also allowed.
