In general, the size of a full-grown Aussiedoodle weighs between 25 and 70 pounds. Given that Australian Shepherds weigh between 40 and 65 pounds and Poodles can be Toy, Miniature, and Standard with weights ranging from four pounds to 70 pounds, it’s no surprise that Aussiedoodles come in several sizes, depending on the size of their parents. A smaller Aussiedoodle, like Toy Aussiedoodles, averages around 20 pounds and 15 inches high. Mini Aussiedoodles weigh closer to 40 pounds and are, on average, around 20 inches tall, and Standard Aussiedoodles weigh 75 pounds and stand around 25 inches in height.
