Exploring the Genetics Behind Color Changes in Yorkies
Yorkies, or Yorkshire Terriers, are a beloved breed of small dogs known for their long, silky coats and wide range of colors. While the breed standard for Yorkies is a blue and tan coat, many Yorkies have coats that range from black and tan to silver and gold. The genetics behind these color changes are complex and fascinating.
The primary gene responsible for coat color in Yorkies is the B locus. This gene is responsible for the production of black pigment in the coat. The B locus has two alleles, B and b. The B allele is dominant and produces black pigment, while the b allele is recessive and produces no black pigment. The presence of the B allele will result in a black and tan coat, while the presence of the b allele will result in a silver and gold coat.
In addition to the B locus, there are several other genes that can affect coat color in Yorkies. The A locus is responsible for the production of agouti pigment, which is responsible for the tan color in the coat. The A locus has two alleles, A and a. The A allele is dominant and produces agouti pigment, while the a allele is recessive and produces no agouti pigment. The presence of the A allele will result in a black and tan coat, while the presence of the a allele will result in a silver and gold coat.
The E locus is responsible for the production of eumelanin, which is responsible for the blue color in the coat. The E locus has two alleles, E and e. The E allele is dominant and produces eumelanin, while the e allele is recessive and produces no eumelanin. The presence of the E allele will result in a blue and tan coat, while the presence of the e allele will result in a silver and gold coat.
Finally, the S locus is responsible for the production of phaeomelanin, which is responsible for the gold color in the coat. The S locus has two alleles, S and s. The S allele is dominant and produces phaeomelanin, while the s allele is recessive and produces no phaeomelanin. The presence of the S allele will result in a black and tan coat, while the presence of the s allele will result in a silver and gold coat.
By understanding the genetics behind coat color in Yorkies, breeders can better predict the colors of puppies they produce. This knowledge can also help pet owners better understand the color variations in their Yorkies.
How to Tell if Your Yorkie is Changing Color
If you own a Yorkshire Terrier, you may have noticed that its coat color is changing over time. While this is a normal part of the aging process, it can be concerning if you are not expecting it. Knowing how to tell if your Yorkie is changing color can help you understand what is happening and ensure that your pup is healthy.
The most common sign that your Yorkie is changing color is a gradual lightening of the coat. This is especially noticeable in the face, ears, and tail. As your pup ages, the black hairs will start to turn gray and the tan hairs will become lighter. This is a normal part of the aging process and is nothing to worry about.
Another sign that your Yorkie is changing color is the appearance of white hairs. This is especially common in older dogs and is caused by a decrease in the production of melanin, the pigment that gives the coat its color. White hairs may appear in patches or all over the body.
Finally, you may notice that your Yorkie’s coat is becoming duller and less shiny. This is due to a decrease in the production of oils that keep the coat healthy and shiny.
If you notice any of these signs, it is important to take your pup to the vet for a checkup. This will help ensure that the color change is due to normal aging and not a sign of an underlying health issue.
Common Reasons Why Yorkies Change Color Over Time
Yorkies, or Yorkshire Terriers, are a popular breed of small dog known for their long, silky coats and distinctive coloring. While the breed standard for Yorkies is a steel blue and tan coat, some Yorkies may change color over time. This is due to a variety of factors, including genetics, age, and environmental influences.
Genetics play a major role in determining a Yorkie’s coat color. Some Yorkies may be born with a coat that is lighter or darker than the breed standard. As the Yorkie matures, its coat may lighten or darken further due to genetic influences. Additionally, some Yorkies may develop a different coat color as they age due to the presence of recessive genes.
Age is another factor that can cause a Yorkie’s coat to change color. As Yorkies get older, their coats may become lighter or darker due to the natural aging process. This is especially true for Yorkies that are exposed to direct sunlight, as the sun’s UV rays can cause the coat to lighten or darken over time.
Finally, environmental influences can also cause a Yorkie’s coat to change color. For example, if a Yorkie is exposed to certain chemicals or dyes, its coat may become lighter or darker. Additionally, if a Yorkie is bathed too often, its coat may become lighter due to the stripping of natural oils.
In conclusion, Yorkies may change color over time due to a variety of factors, including genetics, age, and environmental influences. It is important to note that these changes are normal and should not be cause for alarm.
Q&A
1. Do yorkies change color??
Yes, Yorkies can change color over time. This is due to the fact that Yorkies have a single coat of fur, which means that the color of the fur can change as the dog ages.

Yorkies can change to a variety of colors, including black, brown, silver, and even blue.
3. How Long Does It Take For Yorkies To Change Color?
It can take anywhere from a few months to a few years for Yorkies to change color. The rate of change depends on the individual dog and its genetics.
Conclusion
In conclusion, Yorkies can change color over time, but it is not a guarantee. Some Yorkies may stay the same color throughout their lives, while others may experience a gradual change in color. It is important to note that the color change is not always drastic and may be subtle. Ultimately, the color of a Yorkie is determined by its genetics and environment.
