In the four-layered classification system provided, which layer is the most specific identification for the animal?

Answer

Breed (Pembroke Welsh Corgi or Cardigan Welsh Corgi)

The hierarchical system detailed outlines four primary layers of classification applied to the Corgi. The broadest layers include the Family (Canidae) and the Species (*Canis familiaris*). A functional layer is the Breed Group (Herding Group), based on utility. The most specific and detailed layer, which codifies centuries of regional selective breeding and dictates adherence to written standards like those maintained by the AKC, is the Breed level itself. Therefore, distinguishing between the Pembroke Welsh Corgi and the Cardigan Welsh Corgi represents the final, most specific classification layer recognized by organizations governing breed purity.
