Well, he's bought them already, so it will just have to be good luck.

It could be worse, at least it was not two bitches, is one male bigger or bolder than the other? Two pups together can be very hard work, I dare say he will have two uncontrolable lunatics running around his apartment, unless he is very dog knowledgable and good at training.
I would suggest that you give him this website address, get him to join up and over the coming 12-18 months we will all try really hard to help him out throughout the trials and tribulations of the pups growing up. I think he might need us. ;-)
P.S. I don't agree with neutering before a pup is fully grown, it will greatly depend on these two pups personalities, they may be ok entire and live happily together or maybe one could be done at 12-18 months or maybe both. It's going to have to be a wait and see I'm afraid as to how they will get on.
