They are not pedigrees. They are crossbreeds bred for funny names 
labradoodles, cockerpoos, sprockers, yorkipoos.
If you're desperate for a dog, go and rescue one that some feckless idiot has already bred and couldn't be bothered to be responsible about.
Don't put money in the pockets of some tosser who has bred a random non-breed so they can call it designer and sniffer at the name.
Labradoodles were bred carefully to be non-shedding guide dogs for blind people with allergies. A lot of thought and work went into breeding these. Shoving a random Labrador and poodle together shouldn't mean charging nearly £1000 for the offspring.
I don't care if IABU :o
