Jack Russell

enero 13, 2021


The Jack Russell is one dog breed that owes its name and its birth to the English Reverend John Russell, a man passionate about fox hunting and, more generally, hunting dogs. The Jack Russell was born out of his attempt to get a dog fromexcellent nose, agile and able to find foxes from the dens.

Often the Jack Russell is erroneously associated with another breed selected by the reverend (Parson Jack Russell), different in both proportions and temperament: while the Jack Russell has shorter legs and is more balanced temperamentally; the Parson Jack Russell has the longest legs and is suitable for running on hunting trips.

Today Jack Russell and Parson Jack Russell belong to two very different standards. In 2000, formal recognition of the Jack Russell managed to highlight the characteristic features of the dog breed: agility, flexibility, vivacity and intelligence. Although the dog breed is characterized by its decidedly small size, the category standards do not allow for classifications «Jack Russell dwarf» or «Jack Russell toy«. More than anything else, it is a dog that stands out for its length rather than for its height and for a thoracic circumference (40-43 cm) that allows it to easily slip into burrows.


The Jack Russell is a tough and resolute dog. Once adapted to family life, the Jack Russell builds a relationship of absolute fidelity (even if it «expects» a closer relationship with the owner). A well-bred specimen is a affable animal, playful and that gets along well with children and other animals; a specimen resulting from poorly controlled selections may present itself as a grumpy, arrogant and aggressive animal towards other domestic animals.


A Jack Russell puppy immediately shows his innate predatory instinct towards the wild and the characteristics of the hunting dog, but it is not aggressive towards the human friend. It is necessary, especially in the first months of life, to make him socialize with his peers and with humans to allow the puppy to explore and get to know. A Jack Russell puppy is still a lively, affectionate, loyal and tireless animal.


The diet of the Jack Russell must be calibrated taking into account the animal’s vitality and specific needs. Generally speaking, a Jack Russell’s daily nutrition must be built on a good percentage of proteins of animal origin, better if of certain origin (in this sense, it is advisable to opt for an industrial type of food). In any case, given the small size of the animal and the enormous expenditure of daily energy, it is advisable to adjust the daily rations by virtue of the type of food chosen: the weight of the ration may increase in the case of moist foods (400-500 g ) or reduce in the case of dry foods (120-170 g). In fact, the recommended doses on food packaging they allow a perfect knowledge of the ingredients, quantities and any supplementary interactions to be administered to the specimen (especially in the first ten months of life).

Grooming and hygiene

The Jack Russell’s cloak it requires different care depending on the type of hair of the specimen. In this case, they exist three types of coat: the «smooth hair», the «rough hair» and the «wire» (even if it is also possible to trace different types of hair such as «broken» that is a type of hair obtained by coupling a «Rough-haired» Jack Russell and one to «Smooth hair», and «teddy bear» or a type of hair obtained by mating a Jack Russell with «smooth hair» and one with «broken hair»).

The «smooth hair» falls a lot especially in the moulting period (this hair requires regular brushing with a rubber glove), the «rough hair» is waterproof but smooth (the care of this hair can include «stripping»), the «wire» hair is very thorny and adherent to the body. The «Stripping» it is a quick and painless practice indicated for specimens with «rough hair» and «wire» hair because it helps to eliminate old and dead hair, pulling it off without cutting it in order to allow a quick and correct regeneration.

To avoid the appearance of other problems it is preferable do not neglect the cleaning of ears, eyes and teeth.


From the genetic point of view, the most frequent pathologies in the Jack Russell are: glaucoma, Perthes disease, epilepsy, skin problems and deafness.

Generally speaking, the Jack Russell is a breed of dog that enjoys good health. Visits to the treating veterinarian, the main vaccinations (distemper, parvovirus, leptospirosis, parainfluenza, rabies and the like), deworming and pesticide operations (useful to avoid diseases such as filariasis and leishmaniasis) will help keep the Jack Russell specimen in good condition. health.
