The Standard Poodle is the original Poodle: a water retriever developed in Germany and refined in France, where it became the national dog. The famous clips started as practical trims for swimming in cold water. The Miniature and Toy were bred down from it later, which is why the Standard is the only variety with the build and drive of a real working retriever.
Poodles are among the most popular breeds in the United States, and the Standard draws a particular family: one that wants a large, low-shedding, trainable dog and has usually done its homework. They arrive asking about allergies and coat care, and they leave asking about sebaceous adenitis, Addison's disease, and bloat, because the breed forums taught them to.
Standards are generally healthy and often live into their mid-teens, but the breed carries a well-documented list: hip dysplasia, inherited eye disease, sebaceous adenitis, autoimmune thyroiditis, Addison's disease, and gastric dilatation-volvulus in a deep-chested dog. Responsible programs test every generation, talk openly about what runs in their lines, and publish the results.
