You might want to check the AKC website. I think they still have a survey that you fill out about your family and it ranks dogs in the order that they would be appropriate for your lifestyle (including kids, shedding, activity level, etc.). I think the first generation labradoodles are pretty predictable in terms of temperament, shedding etc. but once you cross two F1's the outcome is harder to determine. If you want additional info on dog breeds I'd be happy to help you. Genetics really does play a huge part in what you are going to end up with so depending on your preferences you need to steer clear of certain breeds. Also you need to take into account if you've had dogs before or if this is your first, what the trainability of the breed is, compatibility with children, etc.
Good luck!
