I am going to Corpus Christi, Tx today and since I will be in the area decided I would purchase a bag or 2 of chicken soup for the dog lovers soul... Gizmo has tried it before and liked it so thats a plus, my question is should I get him Puppy, Adult or LIGHT Adult? I had him on California Natural Chicken & Rice Puppy but he is now 20 months old so I needed some quick advice before we leave today.... anyone? Thanks!
