I am just curious what you are all feeding your puppies? I have a 12 week old named Diesel and we are feeding him "Chicken Soup" puppy formula and he seems to be doing good on it. He seems to like it a lot, never any problems finishing what we give him. However, he has some rancid gas. He can clear the room. I guess my question is, do you think I should try something else? Our local petstore has all the major brands and also a lot of brands that aren't mainstream. Any suggestions on a certain food from anyone that has had this problem?? Thanks guys and this site is the best.
