Cash him in for a Boxer.
Socialize, socialize, socialize.
You have until your pup is about 16 weeks to build the foundation for a well balanced and socialized dog.
Know your breed characteristics and be prepared to take care of that breeds needs.
Crate training is the only way to go, IMHO. I have an 11 week old German bred GSD puppy (my 11 month old Chesapeake Bay retriever recently passed away). I do have an advantage of being retired, so my guy is with me 24/7....but it took me less than a week to get him potty trained.
Have fun.....
That was my first thought, too!! :)
