I think the potato chip you're talking about is lays
If your little guy has been neutered, I think either a boy or girl will be fine..Everyone always says the boys and girls get along better, but, I only have one boy, and the girls are always picking on him..so, I think the choice needs to be yours as to whether a boy or girl would be right..maybe you should go in to the home and let the puppy pick you..just take the one that comes up to you and doesn't shy away...if you don't really care what you get, then letting them pick you is the best way to do it..

good luck..
