All I can add is that....regardless of breed....
a puppy is a puppy is a puppy!
I have sat and cried in the back yard over my F1B Labradoodle who at the time was about 2-3 months old and a big nipper.....She just wouldn't stop it! Though she wasn't being mean, it did hurt and I was tired of all the pant legs and the shirt tails that were ripped with those razor sharp puppy teeth......BUT, it passed!! All of a sudden that annoying behaviour was gone!! (Not without training her, with patience and praise and yes, with firmness, too....but one day she was over it!)
I'd say don't worry about anyone's misgivings....or troubles....this breed is the best we have ever had and the easiest to train!!
We have had, shelties, schnauzers (mini and standard), Irish Setters,
shepherds, an afghan and cocker spaniel. Labradoodles are the BEST!
You will be so blessed with your new pup!!

PS the second doodle never nipped, she's a licker....and a totally different personality than the first....she is easier, too....I think because the first one is so smart, she is thinking, thinking, thinking about whether to mind, or not.....Abby minds without question! Coco minds, but not always immediately!!
