What is an animal with both parents of the same breed and with registration papers considered?

An animal with both parents of the same breed and with registration papers is classified as purebred. The term "purebred" refers specifically to animals that belong to a recognized breed and meet the established standards of that breed, which often includes a documented lineage. These registration papers indicate that the animal has known ancestry and conforms to breed characteristics.

In contrast, mongrels and mixed breeds refer to animals that result from the crossing of different breeds or types, lacking the specific lineage or breed identification associated with purebreds. Hybrids typically refer to the offspring resulting from the mating of two different species or subspecies, showcasing a different context regarding animal breeding. Recognizing these distinctions is crucial for understanding breed classification in agriculture and animal husbandry.
