I have a 15 week old black lab and have been feeding him chicken soup for the puppy lovers soul large breed. He's around 25 pounds and I started off feeding him 1 cup three times a day but he always had really soft stools. I cut him back to 1 cup twice daily and his stool got a lot better but he is starting to look really thin and I'm worried he's not getting enough food. The bag says to feed him 3 1/4 to 4 1/3 cups a day but from what I've read on here manufacturers always are high on the amount to feed per day. Would like some input on how much per day I should be feeding him and any additional food I could add to his diet to help firm up his stool.
