Well, jules, the labradoodle was bred for a purpose. It was bred in Australia by someone who was trying to breed an ideal assistance dog. The cross was tried as one that should suit. It ought not to moult, it's a good size, it ought to be a good learner (the poodle being one of the most intelligent breeds) and it may have the calm temperament of the labrador without the bounciness of the poodle.In that respect it is no different from true breeds, such as the Dobermann ( bred for a tax-collector) !
Trouble is (and this can happen to pedigree breeds) fashion takes over and in no time people are breeding 'anything and everything' to produce the pups.
I plead gulity to having cockerpoos. They are here because of an accident, when the poodle got in with the Am cocker bitch ! I didn't know there was such a deliberate cross but fancied that the result would be worth keeping to term rather than terminating . This proved correct. They've proved delightful, intelligent dogs. (The character, intelligence and activity are far more poodle than cocker and they don't moult, though the coat has a cocker element to it. . I gave some pups to Hearing Dogs for the Deaf, where they proved such a success that the organisation has, reportedly, since had the same cross repeated 'in house'.. One of 'mine' was a star of their demonstration at Cruft's one year and has featured for them on TV, so a cross can be useful.
What I don't hold with is the mating of breeds just for novelty and fashion, a marketing exercise just for those people who must have something different with a silly name to match.
