In little decades, this small dog of rare equipped beauty and of the typical temperament of the terrier, has changed trade, transforming itself from dared annihilator of rats in dog from company for excellence and is successful to conquer the admiration, the interest and the heart of most numerous admirers in all the continents, becoming between the breeds more popular of the world. Its origins are enough uncertain and its formation, like it we know, we are relatively recent and laughed them approximately to the half of XIX the century. Boost in the county of York seems that towards 1870, some laborers wool manufacturers of the Scozia moved themselves in the pressed ones of the city of Leeds, situated to the river close. In this zone the Airedale had already seen the NATO them: terrier of remarkable size and a a lot poured them. Some quite think that Yorkshire and Airedale are become related to you, perhaps for the characteristic of both the breeds of having the cape of black color to the birth, in order then to change ink. The already present Broken Haired, a variety of terrier by now extinguished, came intercrosses with the dogs capacities to you from the Scottish laborers.

Therefore a called Broken Haired Scotch was obtained dog, from the hair enough along, great hunter of rats, that it was used also in "ratting", that is the capture to time of the greater possible number of rats, activity that it came forbidden in England in 1912. Of leggermente advanced ransom to that one of the Yorky (the name is this with which the race often comes affectionately called), the Broken Haired Scotch divenne the faithful companion of laborers wool manufacturers, millers and miners who if they served some in order to hunt the present rapes in great number in the factories, in the botteghe, in the flour mills and the mines. In this terrier he second seems that it was immesso also blood of Maltese, of Bichon and, some students, also of Manchester, Black and tan Toy Terrier and Dandie Dinmont, even if of these last crossings not there is some sure news. Prototype of the race is considered from much Huddersfield Very, been born in 1865 and possession of the fixed characteristics then from the breeders working in consanguinity. The race came second recognized from the Kennel English Club in 1886 (others in 1887), and in 1898 detailed standard came written up one.
Its beauty very soon attracted to the attention of numerous cinofili and the Yorky divenne the companion of many personages in sight, rising to fashionable dog and a lot demanded, thanks also to its moral dowries. The great Italian cinologo Fiorenzo Fiorone therefore described the Yorkshire Terrier in years ' 40 of XIX the century: "E' one true zootecnica wonder: you figure a muff of serico hair, to inks vanished of gold, moventesi silver and lead with great rapidity, like if invisibile machine were animated from a sage which has to prow one small black tip, that it is that one of the nose and to breast a short prominenza, species of rudder, that it is the extremity of the tail, the all wonderful agitantesi with one agility and rapidity ".
Today the race is known and raised to highest levels all over the world, in particular way, beyond that in England, in France, Germany, Spain and Holland. In Italy a specialistico breeding had itself towards the end of years ' 40 of XX the century: that one of Mr. V.E. Brizzolesi of Genoa that it selected with affisso "the Blue Toys" and imported various riproduttori of high class from England. Until years ' 70 of XX the century, but, the number of the subjects produced in our Country was meager and single from 1972 constant increase began one that has carried to record in the Books of the Origins 3885 subjects in 1997 and 3495 in 1998. The race is today continuation from the Italian Society Amatori Yorkshire Terrier (S.I.A.Y.T.).
Character the Yorkshire Terrier has still today not forgotten its origins about hunter and he demonstrates it endured if of he has the occasion, since he succeeds without difficulty to capture the roditori small that succeed in stanare. E' the most intelligent dog and much becoming attached to the master, but a po' dispotico in family where, if it comes granted to it, it will stretch to impose its personality. E' a good friend of the children, but does not have to be allowed they to deal it like a giocattolino, because it expects respect. Equipped of olfatto and heard you ended to me, is an excellent guardiano that inform with barking insistent and po' arrogant of a every noise suspicion. The great courage of which the door is equipped also to assault an eventual intruder. With the strangers it is moderately mistrustful and single after to have known well them it grants greater confidenza. Much cleaning up, demands little of attention to the eyes that sometimes could have an excessive lacrimazione that goes daily cleaned up with products adapted.
