The Aussiedoodle, also called the Aussiepoo, Aussiepoodle, or “Big Ball of Fluff” (a term I coined), is a mix between an Australian shepherd and a poodle. Full-grown dogs range in size from 20 to 70 pounds, depending on if they’re a “Toy,” “Mini,” or “Standard.”. They come in different colors and patterns, but the most popular.
