We have a 7 yr old Doodley girl, she is absolutely gorgeous and we all love her to bits. She is such a happy dog, very bouncy though, she still acts like a pup, loves her ball, and adores people, any people 
However if I had my time again I would not get a Labradoodle.
I thought we had done a lot of research, we planned getting her for a year, went to what we thought was a reputable breeder, saw her with both parents. I asked health questions and really felt quite smug we were being responsible people. I didn't know this forum existed then, if I did I would have realised we didn't ask enough questions.
At nine months she was diagnosed with hip dysplacia and then at four she was diagnosed with Addisons disease. At the time my vet couldn't diagnose, we thought she was dying. We were able to get an emergency apt at Liverpool animal hospital where she was diagnosed and kept in for a week. Her Addisons is now managed with a monthly injection and her life expectancy is normal. She also has a couple of other minor ailments.
Our current pet insurance is £120.00 per month, this will go up again in November, and we don't put everything through insurance.
I don't think you can ever guarantee a perfect healthy dog no matter how much research you do but I think these type of crossbreeds are so popular now that there are some really despicable people out there who breed and have not experience or don't care about the consequence to the dogs. They are cute and gorgeous looking dogs, I have yet to come across a bad tempered one and they are so loving but so are many other breeds who are better regulated.
Choose very carefully would be my advice no matter what breed you go for. Whatever you decide you will have so many years of fantastic doggy love
