Coat and saliva samples from more than thirty poodles were sent from Australia to Blum's doctor. Unfortunately, Mr. Blum was allergic to all of the samples. Wally Conron, who worked for Australia’s Royal Guide Association's breeding program, suggested crossing a Labrador retriever and a Standard Poodle and see if one didn't trigger Mr. Blum's symptoms. Conron tried the test cross with a Standard Poodle named "Harley" and a Labrador retriever named "Brandy.” Harley and Brandy had a litter of three puppies. Coat and saliva samples from the puppy's coats were sent to Hawaii. This time, Mr. Blum wasn't allergic to one of them. The puppy also had a good temperament and was very friendly. Conron named the puppy "Sultan". Conron trained Sultan for eighteen months until he was ready to be a good service dog. Sultan was then shipped to his new home. Sultan is the first labradoodle on record.
