When you picture a Yorkshire Terrier, you likely imagine a tiny dog with a floor-length, silky blue and tan coat strutting through a dog show ring. Yet, the world of these compact canines extends far beyond that classic image. Breeders and genetics have produced several distinct variants, coat patterns, and size categories that all fall under the umbrella of the modern Yorkie. Whether you are looking for a show-quality companion or curious about rare color mutations, understanding the different types of Yorkies helps you navigate adoption, breeding standards, and care needs with confidence.
The standard Yorkshire Terrier remains the blueprint for the breed, governed by strict kennel club rules regarding size and color. However, genetic anomalies, intentional crossbreeding, and selective pairing for smaller statures have created a diverse family of dogs. From the tri-colored Parti Yorkie to the controversial Teacup variant, each type brings distinct physical traits and health considerations. Knowing what separates a purebred mutation from a designer mix ensures you can properly vet breeders and provide tailored care for your specific dog.
The Classic Yorkshire Terrier
The standard, or original, Yorkshire Terrier is the baseline recognized by major kennel organizations worldwide, including the American Kennel Club (AKC). Developed in the nineteenth century in Yorkshire and Lancashire, England, these dogs were originally working terriers used to catch rats in textile mills. Despite their dainty appearance, they retain a bold, fearless terrier temperament.
According to official breed standards, an adult classic Yorkie should weigh no more than seven pounds. Their crowning glory is their straight, fine, single-coat hair that lacks an undercoat, which makes them produce less dander than double-coated breeds. The classic color profile develops over time; puppies are born black and tan, transitioning into the signature dark steel blue and rich tan as they mature into adults.
Parti Yorkies and Tri-Color Variants
While standard Yorkies feature a strict two-color combination, Parti Yorkies introduce a third color into the mix. A Parti Yorkie displays white patches alongside the traditional black, blue, and tan. This distinct pattern is the result of a recessive piebald gene that has been present in the gene pool for generations.
In the late twentieth century, breeders began selectively pairing dogs carrying this trait, leading to widespread recognition. The AKC officially recognized the Parti Yorkshire Terrier as a purebred variant eligible for registration and competition. Aside from their striking tri-color coats, they share the exact same lively personality, intelligence, and compact build as their classic counterparts.
Biewer Terriers
Often discussed in the same breath as Yorkies, the Biewer Terrier (pronounced beaver) is recognized today as a distinct purebred breed rather than a simple color variation. Developed in Germany in 1984 by Werner and Gertrud Biewer, these dogs originated from standard Yorkshire Terriers that possessed the recessive piebald gene.
Biewers feature a piebald spotting pattern with white, black, and tan markings. They possess a sweet, slightly more laid-back disposition compared to the fiery classic Yorkie, though they still love to play. Their coats require the same meticulous daily brushing to prevent tangles and matting. For official breed guidelines, you can review the American Kennel Club Biewer Terrier Standard.
Teacup Yorkies
The term "teacup" describes a size category rather than a separate breed or official variant. Unscrupulous breeders often market teacup Yorkies as rare or exclusive, charging exorbitant prices for dogs that weigh under four pounds at maturity.
Breeding for extremely small stature involves selecting the smallest runts of a litter to breed together, a practice that frequently introduces severe health complications. Teacup Yorkies face elevated risks of hypoglycemia, patellar luxation, collapsing trachea, and fragile bones that break easily from minor falls. If you are considering a very small dog, adopting an adult or purchasing from an ethical breeder who prioritizes health over extreme miniature size is vital.
Designer Yorkie Mixes
When breeders cross a purebred Yorkshire Terrier with another dog breed, the result is a designer hybrid. These mixes aim to combine the affectionate, portable nature of the Yorkie with specific traits from another breed, such as lower shedding coats or sturdier builds. Popular designer mixes include:
- Morkie: A cross between a Yorkie and a Maltese, known for an affectionate, lap-dog personality and a soft coat.
- Yorkiepoo: A mix between a Yorkie and a Miniature or Toy Poodle, valued for an intelligent mind and a curly, low-shedding coat.
- Chorkie: A hybrid of a Yorkie and a Chihuahua, resulting in a tiny, highly vocal watchdog with fierce loyalty.
- Shorkie: A cross between a Yorkie and a Shih Tzu, featuring a sturdier frame and a playful, family-friendly demeanor.

Coat Variations and Mismarked Yorkies
Genetics occasionally produce puppies that do not conform to strict kennel club color requirements. These are known as mismarked Yorkies. A classic Yorkie with an unexpected patch of white on its chest that exceeds standard size limits, or a dog with silver-gray tones instead of dark blue, falls into this category.
Mismarked dogs cannot compete in conformation dog shows, but they make exceptional, healthy family pets. They carry no genetic disadvantages simply because their fur color deviates from the rigid show ring rulebook.
Grooming and Maintenance Across Variants
Regardless of which type of Yorkie you choose, coat maintenance requires a serious time commitment. Because Yorkie hair grows continuously instead of shedding out in seasonal bursts, daily brushing is non-negotiable to prevent painful mats. Many owners opt for the "puppy cut," a short, uniform trim that keeps maintenance manageable.
Bathing should happen every one to two weeks using a gentle, moisturizing canine shampoo to protect their fine hair. Regular dental hygiene is equally critical; toy breeds are notoriously prone to periodontal disease due to crowded teeth in small jaws. Brushing their teeth daily with dog-safe toothpaste prevents costly veterinary dental procedures down the road.
Frequently Asked Questions
Are any types of Yorkies truly hypoallergenic?
No dog is 100 percent hypoallergenic, but Yorkshire Terriers and their single-coated variants produce fewer allergens than double-coated breeds because they lack an undercoat and shed very little hair. Dander attached to saliva and skin flakes still exists, so spending time with a Yorkie before bringing one home is wise if you have severe allergies.
How big do standard Yorkies get compared to Biewer Terriers?
Standard Yorkies typically weigh between four and seven pounds and stand about seven to eight inches tall at the shoulder. Biewer Terriers are very similar, usually weighing between four and eight pounds, though some lines can lean slightly sturdier.
Why do some Yorkie puppies change color as they grow?
Yorkshire Terriers carry a fading gene that alters their pigment over the first one to two years of life. Puppies are born with black and tan coats, but as maturity approaches, the black hair shafts transition into a metallic steel blue while the tan markings become lighter and richer.
Are designer Yorkie mixes healthier than purebreds?
Not necessarily. While hybrid vigor can sometimes reduce the incidence of certain line-specific hereditary disorders, designer mixes inherit health risks from both parent breeds. Responsible breeding practices and health-tested parent dogs matter far more than whether a puppy is purebred or a mix.
