Dog Food for a 1 year old

Our pup is now one. She was on Puppy Chow for her first year. The trainer told me to get her off the Puppy Chow because it has so much sugar in it and it isn't good for her. She suggested I cook chicken breasts and hamburger for her to eat, serve it with yogurt, and the list went on and on. I thought that was a little extreme. I want to give her a good dry food, but I am not sure what brand to use.

What do you give your dog who is over a year old? I want something that helps her joints, coat, digestive system, and craziness (if that is possible :] ).
