To the OP - the frequency and consistency of the poo you're describing could be a concern. At the pup's age, getting a fecal test would be a good idea.
There are better foods out there than what you're feeding, in terms of ingredient sourcing, history, etcetera. Some better brands are Orijen, Innova EVO Small Bites, Solid Gold Barking at the Moon, Wellness (avail. at Petco/Petsmart). Are you near a feed store at all? Oftentimes, feed stores sell very good dog food.
