The White Yorkie’s Name
The American Kennel Club does have strict regulations regarding the standards of the attributes of a particular Yorkshire Terrier dog. These standards have something to do with the four official colors of a Yorkie: black, tan, blue, and gold.
White is nowhere on this list, but many people have heard of the rare White Yorkshire Terrier, and this gained a lot of interest from people who wanted one.
What is a white Yorkie called? Yorkies come in a huge array of colors but some of which are recognized by the AKC. One of the rarest types of Yorkie is a Parti Yorkie as it contains white patches with tan and black in their coats.
This article will allow you to discover more about White Yorkie and why the American Kennel Club has not recognized it. It is also essential to know the science and genetics behind the whiteness of a Yorkie.
What Is A White Yorkie?
As the name implies, white Yorkies are considered to be Yorkshire Terriers with only white fur. The only difference is that purebred Yorkies come from specific color combinations and then change when they reach adulthood.
It is also possible for Yorkies to fall somewhere between these color combinations. Some have black and gold, while some can get blue tan coats.
If you ever come across a white Yorkshire Terrier, there is a bigger chance that the dog is actually a white Yorkie mix. It is a product of cross-breeding a Yorkshire Terrier to another breed.
It can be either West Highland Terrier or even a Maltese, also known as Morkie. If this is your dog’s case, there is nothing to be ashamed of.
All puppies have their own unique qualities in terms of shapes, sizes, and bloodlines. But many institutions like the AKC need to track and maintain strict regulations regarding breeding standards to ensure the purity of a very diverse dog breed.
With that being said, there are at least two ways to figure out a true Yorkshire Terrier with white hair.
White Yorkie Genetics
If you are looking for a full-on all-white coat for a Yorkshire Terrier is actually highly unlikely. But there are some cases where Yorkshire Terriers sometimes have developed some portions of white in their adult coats, which is a more common occurrence.
To figure out what is happening in these spots and portions, you need to understand the genetic factor. You might be able to understand why your Yorkshire Terrier breed’s coat is white and how it might end up all-white or partially white.
The Yorkie Puppy Coat
In terms of the general rule, purebred Yorkshire Terriers carry some particular gene that naturally takes their coat from one color to another. It is similar to all nearly purebred Yorkshire Terriers born with black and tan coat color patterns.
Aside from that, it’s worth mentioning that the area covered by the color can vary depending on the puppy itself. Usually, around six months, they will start the transition process from puppy coat to adult coat.
Once the transition is complete, you will know with certainty what your adult Yorkie dog’s coat will look like. However, if you ask some experienced breeder familiar with Yorkshire Terrier genetics, they can often estimate what your Yorkie’s adult coat color will be.
They have a fair share of knowledge when it comes to the genes of each parent dog.
Basic Yorkie Coat Color Genes
Like many dog breeds, Yorkshire Terriers can inherit two basic color pigments. First, the eumelanin, and the second is the phaeomelanin. If all dogs have just two pigments then, how come so many different canine coats exist nowadays?
The answer to that is because other genes interact with eumelanin and phaeomelanin. As a result, it will alter all the final coat coloration when two parents have their puppies.
These genes may be coming from one or even both genes of their parents, and the impact of these color-altering genes will be more dramatic.
It is when a Yorkie puppy inherits the same genes from both of its parent’s genes. When interacting with phaeomelanin, the basic red color will become cream, tan, yellow, gold, orange, red, and sometimes burnt red.
The C-locus gene is responsible for getting how light or dark the phaeomelanin manifests in your adult Yorkie. On the other hand, when interacting with eumelanin, the basic black becomes brown, blue/grey, or even pale brown.
The G-locus gene is the gene responsible for turning black pigment to gray or dark blue.
The Origin Of The White Coat Color
It is an interesting topic that many vets are still trying to figure out because there are fewer scientific studies that explain how a dog can have a white coat. It is whether it has something to do with the full-on white coat of the dog or just some patches or patterns.
White hair or fur can always depict the total absence of any pigment in your Yorkie’s coat. When the cells that are supposed to be producing pigment do not produce any pigment at all, the resulting coat will be white.
However, this does not apply to the skin, and the absence of pigment on areas of the skin will cause some dogs to have pink skin, pink nose, and blue eyes.
Certain genes are responsible for the color patterns of any dog’s coat or hair. It can also create white spots of patches, including the H-locus, M-locus, S-locus, and the T-locus genes.
Yorkies that are considered to be off-standard are rare because of the strict regulations of the AKC.
Some breeders even believed that these white Yorkies are not technically purebred and many of them are just the result of cross-breeding two breeds of dogs to achieve the whiteness some of their customers are looking for.
Just be mindful that white sometimes signifies the lack of pigmentation, and it somehow correlates to different health issues of your Yorkies.
