I use Nutro products... I tried to use the Nutro Ultra (they were out of the Nutro Natural Choice wet puppy food and I needed something for them) and my girls didn't like it.. So I gave it to my boyfriends dog and he didn't like it
I use Natural Choice Lamb and Rice wet puppy food (2 spoonfuls for each) and then I leave Natural Choice Chicken and Rice small puppy bites (itsa green bag with a beagle on it) for them all day.. I haven't had runny poop or anything since I've had them on it..
Theres better food out there but I like Natural Choice be/c its easily available to me in my town (and i haven't had anything go wrong)..
I tried Royal Canin (didn't like it), Purina Puppy Chow (I use it as a treat

), Solid Gold, and a few others..
