It depends who you are talking to, there are some Biewer clubs who believe that there is a good deal of difference between the two, while other clubs say no difference. Some parti breeders who also breed biewers say no difference while other parti breeders believe in keeping the lines different. The Biewer seems to have come from a parti yorkie, but Mr. Biewer bred them to get a certain look and certain coloring. I think he had a higher purpose than to just sell pets, and was interested in creating a complex variation of the Yorkie. There is a "standard" look to the Biewer, however, there is no written standard for a parti, it's just a yorkie with a color fault. Here's what the mother club of the Yorshire Terrier says about partis.
Quote:
The AKC Breed Standard and YTCA Code of Ethics do not recognize any
other color dogs than noted above. This includes all gold, born blue, liver
(also known as red or chocolate), and parti-colors. One of the reasons for
avoiding breeding "off-colored" Yorkies is because it could be a genetic defect
that may affect the dog's health. Some health problems can include, but aren't
limited to, severe skin problems, allergies, total hair loss and in some cases
long-term illness and/or death.
A responsible breeder will not intentionally breed for undesirable traits.
On very rare occasions, a breeder will have a puppy born with a color anomaly.
That puppy should undergo careful health screenings before being placed in a
spay/neuter (non breeding) home. A breeder should certainly never
promote these deviations as being desirable or rare. http://www.ytca.org/faq.html#B |
