I recently got a male puppy and was worried about their play being too rough. Not sure if I'm just used to it now, or they've calmed down a bit but I don't worry about it anymore.
It's hard to tell from reading a post on a forum but chances are that if the pups not getting hurt then it's not really too rough. My female was getting towards 10 months old when I got the puppy and obviously much larger than him so if she had wanted to hurt him, she could have done it quite easily.
If you're worried, I'd probably suggest either seperating them when it gets rough or redirect them to something else.
