How big is an Australian Labradoodle? Keep in mind there is a range for each size. Also, considering weight alone can be misleading. An Australian Labradoodle can look as big as a Labrador Retriever but may actually weigh considerably less due to their “floof!” They are very light on their feet and if welltrained, can be easy to manage at any size.
