Good morning and welcome to the forum.
I hate to be the one to address this issue with you (I wish that your breeder would have spoken with you about it...) but some Labradoodles DO shed. Especailly F1 dogs. Do you know if your dog is an F1? If so, there is a good chance that the shedding could slow down some, but probably will not cease.
However...if your puppy has not been a shedder to date, and just started, she is at an age where she most likely is "blowing" her puppy coat. When a dog nears her first year mark, she often will shed her puppy coat and replace it with the adult coat.
Labradoodles are very different from each other because there is no breed standard set at this time and since the breed is evolving, it is common to find shedding Labradoodles. This is due to several factors, but breeders are doing a disservice if they don't tell buyers that there is a real possibility that their dog could shed, especially if that puppy is a first and even second generation.
I hope this helps...
We'd love to see a picture of your puppy if you'd care to post one!
