Lucky you!! A new puppy. You'll probably get lots of advice on puppy selection but you've got about 7 weeks to evaluate the pups.
The standard approach is to pick one with a middle-of-the-road disposition. Stay away from the bully and the wallflower. One test is to put the pup on it's back and hold it there. The ideal behavior is to have the pup fight to get up for a little while but eventually lie still. Some pups will not stop fighting you and others will just lie quietly and not fight at all. The more you watch them the more you'll be able to determine their behavior. BTW why are you disregarding females, believe me they make great hunting dogs too. Good luck.
