I would suggest looking at the humane society or search for a local boxer rescue organization. Most of these poor dogs have just been given a bad break in life and need a second chance. Plus, if you get an older dog, you don't need to go through the whole house-breaking thing. I got my adult dog from the humane society and besides being a great dog, he learned all the basic commands and his new name in less than week. Adult dogs are just as easy as puppies to train, despite the old saying.
Please, please check the humane society or even the ARF foundation (
www.arf.ab.ca) before going to a breeder. There's a lot of boxers/boxer crosses at the humane society right now. If you're adamant about getting one from a breeder, make sure it's a reputable breeder and not a "backyard" breeder. There's purebred and there's "purebred". If you're not sure how to tell if the breeder is okay, can offer some suggestions in what to look for. I've trained dogs for about five years so if you have any questions, I'd be more than happy to help.
