The term 'pedigreed' is used to describe animals that have a known and documented ancestry. A THOROUGHBRED is a type of pedigreed horse, which has a documented lineage of at least three generations of PUREBRED horses. Blooded is another term for pedigreed, referring to the fact that the animal's lineage is known and documented. PUREBRED is also a term for pedigreed, meaning that the animal's parents are both of the same breed.
