The original Labradoodle was originally developed in 1989, in Australia, to be a hypoallergenic guide dog. It is the cross between a poodle and a Labrador.
Popularity grew so rapidly, many back yard breeders chasing profits began breeding any poodle with any Labrador they could find, ultimately ruining much of what the Labradoodle was meant to be. Many typical Labradoodles today are far to hyperactive to serve as service dogs, which is their original intent.
Along came two research facilities in Australia, with the goal of saving the breed and creating their own pure breed Labradoodle by breeding multiple generations of Labradoodle, as well as carefully infusing certain breeds into the bloodlines, mostly American and English Cocker Spaniels. This then became what is now known as an Australian Labradoodle.
An Australian Labradoodle is a pure breed in the making, giving it consistent traits in both looks and temperaments while breeding, which isn't possible with typical Labradoodles. Australian Labradoodles are carefully bred to be non shedding and have calm even temperaments, often making them great service dogs.
