The question is a bit unclear, but the phrase “dog show 20” most commonly refers to the 2020 Westminster Kennel Club Dog Show. In that event, the Best in Show winner was Siba, a standard poodle.
If you meant a different competition (for example, the National Dog Show, or a junior/4‑H event) or a different year ending in “20,” say which show and year you have in mind, and more precise information can be provided.
