What size is a full-grown Sheepadoodle?

Sheepadoodle puppies can grow up to weigh between 30 and 80 pounds. How big a full-grown Sheepadoodle gets depends on the parents of the puppy. The Standard Sheepadoodle is the most common size, weighing 55 to 80 pounds and standing around 19 to 24 inches in height. Breeding an Old English Sheepdog with a smaller Standard Poodle results in a Medium Sheepadoodle, which weighs 40 to 55 pounds. Crossing a Miniature Poodle and an Old English Sheepdog results in a Mini Sheepadoodle, the smallest of the Sheepadoodle crosses, weighing in at less than 40 pounds and standing around 15 inches in height.
