Hi Angelaj, welcome!
Linda is right and I agree with her assessment of the way Labradoodles are bred.
I have heard of breeding back to a Lab (although I don't think it would be wise) but when it is done, I think it is when the "Poodle" genes are too strong...and that would not happen, in my opinion, until many generations of breeding and back breeding to Poodles.
The idea, as Linda mentioned, is to breed Lab traits but have Poodle coat qualities...and by breeding back to a Lab, you are increasing the chances of Lab type coats...hey, breeding Lab Coats! LOL (Okay, sorry, couldn't resist.)
Now, this is not to say that your puppy is anything but adorable and wonderful ... most people, I have found, really want the Lab qualities in their puppies...but you might have a puppy with quite a bit of shedding. (But, also with a lot of sweet Labrador traits!)
Be sure and post his picture!
