Howdy Brandon,
When looking at pure bred dogs and you have decided on a breed your most important move is finding a reputable breeder. Check out some dog shows and talk to the people. Get a hold of a magazine. I think there is a magazine dedicated to Boxers. You can find the mags. at Petsmart or other pet store. Another way is checking with the breed rescue. If you don't need a show dog but you want a purebred this is the way to go. If all this research seems a bit much then just go down to an animal shelter and pick up something there.
