Breed Comparisons
Yorkshire Terrier vs Biewer Terrier: Side-by-Side Comparison
They look similar, come from the same origin, and both fit in your lap — but there are real genetic and temperamental differences between Yorkies and Biewer Terriers.

The Common Ancestry
Biewer Terriers descended from a parti-colored Yorkshire Terrier litter born to Werner and Gertrud Biewer in Germany in 1984. For decades they were considered a Yorkie color variation — until UC Davis research in 2007 confirmed that Biewer Terriers have a genetically distinct identity from Yorkies, justifying separate breed recognition. The AKC formally recognized the Biewer Terrier as its own breed in 2021.
Color: The Most Obvious Difference
- Yorkshire Terrier: Traditional — steel blue and gold/tan in adults. Also produced in parti (blue/gold/white) and in rare chocolate variations.
- Biewer Terrier: Signature tricolor — blue/black, gold, and white with white belly and legs. Color pattern is specifically defined by breed standard.
Temperament Nuances
Both breeds share the confident, devoted terrier personality. Breeders and owners who have raised both often describe Biewer Terriers as slightly softer in temperament — less terrier-reactive, a touch more mellow — while still being lively and spirited. Yorkies can be more assertive and independent. These are subtle differences — both breeds need consistent training and both can have strong personalities.
Size and Structure
Both breeds fall in the same size range: 4–8 lbs at maturity. The Biewer breed standard calls for very similar proportions to the Yorkie. In practice, they're essentially the same size and structure with different coloring.
Health Testing
Both breeds require DNA testing for Progressive Retinal Atrophy, Degenerative Myelopathy, and other testable conditions. Because Biewer Terriers are rarer, finding a breeder with both Biewer-specific health testing AND genetic color documentation is harder — but equally important.
Rarity and Cost
Yorkshire Terriers are one of the most popular breeds in America — widely available from reputable breeders. Biewer Terriers are rare — far fewer ethical breeders produce them. This scarcity means higher prices (typically $2,500–$4,000+ from health-tested breeders) and longer waitlists. If you want a Biewer, plan ahead and get on a trusted breeder's waitlist early.
