What are your goals with this dog? What did you plan on doing with her?
How much do you trust this breeder? Any idea on how she was trained before you got her? I know you said she's green...but its a big deal on how she was actually trained and not what she actually knows at this point.
She might not have high food drive...but most dogs, no matter how uncomfortable, if they have any sort of food drive will take food from anyone. What you're seeing, isn't what I witnessed with the bitch I got a month ago at 2.5...but each dog is different. Without seeing the dog in person, its really hard to tell you what's going on with her.
