1. Documentation:
* Pedigree Papers: The most reliable way to know if your Yorkie is full-bred is to have a pedigree. This document traces the dog's lineage back several generations, proving its ancestry.
* Registration: If your Yorkie is registered with a reputable kennel club (like the AKC or UKC), it's a strong indicator of full-bred status.
2. Physical Appearance:
* Conformation: Compare your Yorkie to the breed standard (available online or from kennel clubs). Look at factors like size, body proportions, coat texture, and head shape.
* Coat: A full-bred Yorkie has a luxurious, silky coat that grows long and straight.
* Color: The standard Yorkie coat color is steel blue and tan.
3. Temperament:
* Personality: Yorkies are known for their spunky, affectionate, and intelligent personalities. If your dog exhibits these traits, it's a positive sign.
4. Breeder's Reputation:
* Reputable Breeder: If you got your Yorkie from a reputable breeder, they should have documentation and be knowledgeable about their breeding program.
5. DNA Testing:
* Genetic Testing: DNA testing can identify specific markers related to breed and confirm a Yorkie's lineage. This is a more definitive approach.
Important Note:
* Physical Appearance Isn't Everything: Even if your Yorkie doesn't perfectly match the breed standard, it could still be full-bred.
* Mixed Breed Love: Even if your Yorkie isn't a full-bred, they are still wonderful companions!
In conclusion, while physical characteristics and temperament can provide clues, the most reliable way to determine if your Yorkie is full-bred is through pedigree documentation, registration, or DNA testing.
