I also wouldn't worry about Adi's weight. Is probably best that he's on the light side rather than the heavy side! It's very hard to lose extra weight for dogs! I am feeding ProPlan to Zoey. I think she likes it pretty well, and the first ingredient is chicken, so Purina is on the right track with this food. Have you looked at Nutro Max or Natural Choice? They make some pretty good foods, but are about the same price as ProPlan and are at Petsmart, Petco, and other pet stores. Dolly is on Nutro Max for now. And I will be keeping Dolly on large breed puppy food until she's 2. Zoey is finally on adult large breed food but she's 1 1/2. Again, there are many varying opinions on here about what to feed. Basically, the choice is up to you, so make sure you feel good about your decision!
