To determine if your Yorkshire is authentic, you should pay attention to the breed’s characteristics. The FCI provides the official breed standard with all the elements to consider when distinguishing a purebred Yorkshire from a mixed-breed Yorkshire. But don’t worry, to make it easier for you, we detail the points that will make it clear if your Yorkshire is authentic:


  1. Toy Size: The Yorkshire’s size is the main indicator of pure breed. The Yorkie is classified as a ‘toy’ or miniature dog, given that its weight ranges from 3.3 lbs to a maximum of 7 lbs. A size larger could indicate a mixed-breed Yorkshire.
  2. Yorkshire Mane: The characteristic coat of the Yorkie is smooth, long, and hanging, never stiff or rough. The mane hangs evenly on both sides of the body, with a dividing line extending from the nose to the tail. The overall appearance is elegant, and its straight posture gives it an imposing look.
  3. Color: The color of the coat stipulated by the FCI for the original Yorkshire is a dark steel blue, without any presence of silver-blue tones, extending from the back of the head to the base of the tail. This color should never be mixed with shades of fawn, bronze, or dark hair. In the chest area, the coat shows an intense and bright fire color. The fire-colored hair should be darker at the root than in the middle and lighten at the tips.
  4. Eyes: The penetrating, lively, and intelligent gaze of the Yorkshire is another characteristic that it is an original Yorkie. Their eyes are medium-sized and not prominent. They are always dark and bright. The edges of the eyelids should be dark.
  5. Ears: The pure Yorkshire’s ears are V-shaped, should be erect, small, and not too far apart. They are covered with short hair, and their color is an intense fire tone.
  6. Tail: We won’t mention the length of the tail because, unfortunately, there are still breeders who continue to cut the tail of the Yorkshire. Whether it is long or short, the Yorkie’s tail is covered with hair, with a darker blue color than the rest of the body, especially at the tip. The tail is carried slightly higher than the level of the back.
  7. Nose: The nose or truffle is always black.
  8. Head: Its skull is small and usually does not show prominence or roundness.
  9. Personality: Although personality can have differences among dogs of the same breed, it can be a clue to the authenticity of the Yorkshire if it meets the dominant character traits in the Yorkie, such as alert and lively attitude, overprotective, barking, and active.

By observing these criteria, you can verify if your Yorkshire is authentic. But if doubts persist, we give you some tips to follow when acquiring an original Yorkshire:



  1. Pedigree: The most reliable way to confirm the authenticity of a Yorkshire Terrier is through a registered pedigree. A pedigree is a document that certifies a dog’s lineage and proves that it is purebred. You can ask the breeder or the dog’s owner to show you the pedigree issued by a recognized canine organization, such as the American Kennel Club (AKC) or the International Canine Federation (FCI).
  2. Trusted Breeder: When acquiring a Yorkie, look for a reputable breeder with a history of responsible and ethical breeding of the breed. Serious breeders will maintain records and documentation supporting the authenticity of their dogs. Also, get references from other satisfied buyers.
  3. Health Certificates: Responsible breeders should also provide health certificates for the puppies, including appropriate vaccinations and deworming. This demonstrates the care and attention given to the dog from an early age.

Remember that purebred dogs can be expensive, so it is important to ensure that you are buying an authentic dog. The best way to do this is through a trusted breeder who can provide you with documentation and guarantees that the dog is purebred. Avoid buying dogs from unverified sources, as you could risk acquiring a Yorkshire that is not authentic and contribute to breeding practices that do not meet healthy standards and without checking the genetic status of the specimens to rule out hereditary problems and congenital diseases.


A mixed-breed Yorkshire is an individual that comes from the crossbreeding of an original Yorkshire with another dog of another breed. They may even descend from mixed-breed Yorkshires bred together for reproduction.

To determine if your Yorkshire is mixed-breed, observe that it does not meet the official breed standard. These are the main signs that your Yorkie is mixed-breed:

  1. Different hair colors.
  2. Larger sizes.
  3. Rougher, hard, woolly, curly, or wavy coat textures.
  4. Dropped or differently shaped ears than the characteristic V-shaped Yorkie.
  5. Any variation different from the pure Yorkshire.

Nevertheless, we emphasize that the importance of the dog is not whether it is purebred, original, or mixed-breed, but that its health status is optimal. There are mixed-breed Yorkshires that are very attractive, original, and adorable. Breed purity is essential for pets that we are going to take to competitions.

To be our faithful companion, it is enough for it to be affectionate, healthy, and its temperament and needs adapt to our lifestyle and preferences.
