HISTORY
In the U.S.A. and Canada white shepherd dogs have gradually become accepted as a distinct breed.
The first dogs of this breed were imported into Switzerland in the early 70s. The American male “Lobo”, whelped on 5th March, 1966, can be considered as the progenitor of the breed in Switzerland. The descendants of that male registered with the Swiss Stud Book (LOS) and other white shepherd dogs imported from the U.S.A. and Canada, gradually multiplied. There exists now a big number of white shepherd dogs, pure bred, over several generations, distributed throughout Europe. For that reason, since June 1991, these dogs have been registered as anew breed with the appendix of the Swiss Stud Book (LOS).

Conveying an important air, the Yorkshire Terrier presents a picture of a vigorous, well proportioned little dog. The whole head is covered with a good fall of hair, under which one finds a small flat skull with a shorter muzzle. The dark rimmed eyes should sparkle and the small erect ears should be rich tan in colour. There should be a good reach of neck and this runs into a compact body and a level topline. The normally docked tail should be dark blue and carried a little higher than the level of the back. The tan legs should be strong and finish with round feet and black nails.
CHARACTERISTICS AND CARE
This glamorous little dog can weigh up 3.1kg (7lb). While often overly pampered, Yorkies still retain their terrier character - it is a mistake to think of them as lap dogs. They have a lively, energetic and spirited temperament and this, coupled with their smaller size, does not always make them suitable pets for young children or the elderly. Bathing and grooming must be done on a regular basis - particularly if the dog is to be exhibited. To protect the hair from being damaged, show people often tie the topknot and coat in wrappers. However, the pet owner can keep the Yorkie looking presentable with the coat trimmed to 2-5cm (l”-2”).
HISTORY
The Yorkshire Terrier is made up of a blend of the Waterside Terrier, a small longish coated terrier seen in Yorkshire for many years, the Skye Terrier from Scotland and the old English rough coated Black and Tan Terrier. By the mid 19th century, these crosses had resulted in a distinct breed type. In 1861, they were exhibited as Broken Haired Scotch Terriers but by 1870, the name had been changed to that of Yorkshire Terrier.
