We all agree that Yorkies steal people’s hearts with their lovely nature and cute appearance. These tiny dogs are typically identifiable by their distinctive blue and tan coats, which set them apart from other dogs in the canine community. However, within the different types of Yorkshire Terriers, you might come across the term “mismarked Yorkie.” This particular coat variation, not among the AKC-approved colors for Yorkies, is associated with one of the seven different  Yorkie breeds.

 Interestingly, mismarked Yorkies often come at a higher price. To help you learn how to make a difference between Yorkie breeds, we decided to introduce you to all the facts about these cuties.

Everything You Need To Know About Mismarked Yorkies

History and Origin

Yorkies have a rich history dating back to the 19th century in England. They were originally bred to catch rats in textile mills. Over the years, they have transformed into beloved companion dogs known for their loyalty and affectionate nature.

Characteristics and Traits

Yorkies are known for their small size, standing at around 7 to 8 inches tall and weighing between 4 and 7 pounds. Their silky, fine, and straight coat is typically blue and tan, and they have a confident and spirited personality.

What is a Mismarked Yorkie?

A mismarked Yorkie is a Yorkshire Terrier that does not conform to the breed standard in terms of coat color and markings. According to the American Kennel Club (AKC), a standard Yorkie should have a blue body with tan markings on the head, chest, legs, and tail. Mismarkings occur when a Yorkie’s coat deviates from this standard.

Common Mismarkings

Common mismarkings in Yorkies can include irregular or excessive white markings, a lack of tan on the head or legs, or even a completely different coat color. These variations may be subtle or more pronounced.

Causes of Mismarkings


Mismarkings in Yorkies are often the result of complex genetic factors. Genes responsible for coat color and markings can sometimes produce unexpected results when two Yorkies are bred together, leading to mismarkings in their offspring.

Breeding Practices

Unscrupulous breeding practices, such as breeding for specific coat colors rather than the overall health and well-being of the dog, can increase the likelihood of mismarkings. Responsible breeders aim to adhere to breed standards and prioritize the health of the puppies.

How is a Mismarked Yorkie Produced?

Genetic Factors at Play

At the heart of the matter are the genes that govern coat color and markings in Yorkshire Terriers. These genes are responsible for producing the iconic blue and tan coat that is synonymous with the breed. However, genetic variation can lead to mismarkings.

Recessive Genes

Mismarked Yorkies often result from the presence of recessive genes in their genetic makeup. These genes may lie dormant in the lineage for generations, only to manifest unexpectedly when two carriers of these recessive genes are bred together. When this happens, it can give rise to puppies with coats that deviate from the standard blue and tan.

Crossbreeding of Mismarked Yorkies

In some cases, mismarked Yorkies can be produced through crossbreeding with other breeds that carry different coat color genes. These crossings can introduce genetic diversity into the lineage, leading to variations in coat colors and markings.

Breeding Practices

While genetics play a pivotal role, breeding practices also significantly influence the occurrence of mismarked Yorkies. Unscrupulous or inexperienced breeders who prioritize specific coat colors over breed standards may inadvertently contribute to mismarkings. Unfortunately, producing rare Yorkie colors often ends up badly. If you buy a puppy from an unreliable breeder, the puppies may show health issues in the future.

Breeding for Coat Color

Some breeders may focus on breeding Yorkies for unique or non-standard coat colors to meet market demands or personal preferences. This practice can increase the likelihood of mismarked puppies, as it deviates from the breed standard.

Lack of Knowledge

Inexperienced breeders who lack a deep understanding of Yorkshire Terrier genetics may unknowingly pair dogs with recessive genes, inadvertently producing mismarked offspring. Education and responsible breeding practices are key to preventing mismarking.

Unpredictable Outcomes When Breeding a Mismarked Yorkie

It’s important to keep in mind that mismarked Yorkies are not the result of breeders doing something on purpose. Instead, they are the result of complicated genetic combinations whose results are hard to predict. Breeders who put the health and breed standards of their dogs first are less likely to make puppies with the wrong markings.

The production of a mismarked Yorkie involves a combination of recessive genes and breeding practices. While these variations can be striking and unique, they are not part of the AKC-approved coat colors for Yorkshire Terriers. Responsible breeding practices, education, and a commitment to breed standards are essential in reducing the occurrence of mismarked Yorkies and ensuring the overall health and well-being of this beloved breed.

Identifying a Mismarked Yorkie

Physical Characteristics

Identifying a mismarked Yorkie primarily involves examining their coat. Look for any unusual or excessive white patches or a lack of tan on the typical areas. However, remember that mismarkings can vary in severity, so it’s essential to consult breed standards for a comprehensive understanding.

Pedigree and Registration

When purchasing a Yorkie from a breeder, ask for the puppy’s pedigree and registration papers. These documents should provide information on the puppy’s lineage and confirm whether it meets the breed standard.

Implications of Mismarked Yorkie

Show Dogs vs. Pets

Mismarkings typically disqualify Yorkies from participating in conformation shows, as they don’t adhere to the breed standard. However, they can still make loving and loyal pets.

Health Concerns

While mismarkings themselves are not inherently harmful, unethical breeding practices associated with them can lead to various health issues in Yorkies. It’s crucial to support responsible breeding to ensure the overall health of these dogs.

Ethical Considerations When Producing a Mismarked Yorkie

Responsible Breeding

Supporting responsible breeding is vital to reducing the occurrence of mismarked Yorkies and ensuring the health and well-being of the breed.

Adoption and Rescue of a Mismarked Yorkie

Consider adopting a Yorkie from a rescue organization or shelter. Many Yorkies in need of loving homes are looking for adoption. On the other hand, adopting rescued and abandoned Yorkies often brings unpredictable plans for the future. Unfortunately, such pooches may show health issues and behavioral problems. Rescued and abandoned Yorkies can show aggressive behavior toward their new family members if they haven’t been properly socialized.

Mismarked Yorkie: Wrapping Up

A mismarked Yorkie is a dog whose coat doesn’t meet the standard of the breed. While mismarkings can vary and may disqualify Yorkies from dog shows, they can still be cherished pets. However, it’s essential to support responsible breeding practices to ensure the health and well-being of these delightful dogs.
