<human>: Can you condense the text into a few key points?

It may seem like a newbie question but i recently got a very shy 14 week Weimaraner puppy. As expected, he has got quite the energy and loves to play with people. Although he is shy with other dogs (frightened, really) he has grown accustomed to my submissive 7 year old shit-poo. as you an imagine, he is quite a bit bigger and stronger than the poor little thing and even though it seems he means well, she does not like playing with him. Though he is not biting, he does have a mean right hook. if he goes too excited nipping may occur.

I felt as the problem would get resolved on its own. Either she would snap at him or start to play. But she just runs and cowers instead. Thinking shes playing, he will continue the act, and I feel bad.

So the question is, what should I do? Do I let them continue in hopes she deals with the situation? or should I intervene and give a firm "no"? Any other suggestions?
