I would like to know that too. Just started my almost 8 week old puppy on Natural Choice Lamb and Rice after slowly switching over from Iams puppy food that the breeder gave him. This was suggested by the dog trainer at a local Petco since it is supposed to be much better (no corn meal etc.). I'd appreciate feedback from someone who actually feeds that to their baby.
Also, how much does a 2.3 pound 8week puppy eat? I put out moistened food for him four times a day, about 1/3 cup each time and he barely eats half of that. I have to coax him to eat out of my hand since that seems too little.
Is it enough food for him or am I being a bit paranoid?
