Well, first - WELCOME and CONGRATS!!!!!!!!! And, good for you for trying to find out what is best for your new baby, that's just awesome!
I would ditch the Caesar instantly - it's really nasty (which probably why it tastes so great). Canidae and Wellness are really good foods. Are you doing kibble or canned?
Just fyi, canned foods are always superior nutritionally to kibble bc they are less processed than kibble - so you could do both, if you like. Some people will free feed kibble - and then give canned twice a day. So, you have a few options there. Wellness makes some wonderful canned foods - some with fish, which is great. Canned gets moisture in their systems as well.
