I have been feeding my little Jack Science Diet, b/c that is what the breeder fed him. He seems to do fine with it, and I know quite a few people that have used this food for years and have never had a problem. I have read on here though, from quite a few people that they don't like Science Diet. What should I do or what do you all recommend?

Jack is about 14 wks old now, and I hate to switch his food. I'm not sure what to do!!!
