I bet they're wonderful dogs personalitywise, but I don't like the hype. They are a mixed breed, not a breed. They started out as an attempt to breed hypoallergenic service dogs, but the attempt failed.
I get upset when I see these labradoodle breeders still trying to boast that all their "purebred labradoodles" are "non-allergy" causing. NOT TRUE! If you cross a lab and poodle, the pups are just as likely to be like a heavy-shedding lab as they are an allergy-friendly poodle.
It's sad when you look on petfinder. You find bunches of labradoodles that were taken to shelters when it turns out that they weren't really allergy-friendly.
