I would normally not tolerate that, but 10 weeks, the pup is treating your daughter like a littermate and would probably do the same with you at this point.

My male dog is very good natured but he was bent on being an alpha as a pup. I fixed it. Basically, I bit him back. I would grab him by the scruff of the neck and growl at him and even shake some. I had to be a little rough. I also would spray a mixture of 3 parts water to one part vinegar at his nose (not his eyes). Now he's one of the nicest dogs I know. A great dog and quite trustworthy. Bite your dog back now and you won't have to later. If the pup gets a little older and after several "convincing" sessions still does this, I'd send it back to the breeder. Like you said, there are too many good ones to feed a bad one.
