The man who created the ‘labradoodle’ says inventing the breed is his “life’s regret” because they are either “crazy” or plagued by health problems.

Wally Conron, an Australian dog breeder, first cross-bred a Labrador and a Poodle for a blind woman whose husband was allergic to dog hair, but says it “opened up a Pandora’s box and released a Frankenstein's monster.”

Today, breeders are not adhering to good practice and producing dogs with health problems, he says, while a “bandwagon” effect means that some are trying to cross inappropriate breeds in an effort to create their own ‘designer dogs’.

Speaking to the Australia Broadcast Corporation, he says that producing the labradoodle is his "life's regret" and he hasn't "got a clue" why people are still breeding them today.

Born in 1989, Sultan was the world’s first labradoodle, created by Mr Conron because it was hypoallergenic and had a good temperament.
