I switched from Timberwolf Ocean Blue to Merrick Wilderness about 3 weeks ago. It's not working too well. Oggie still has soft stools almost all the time. I didn't think it'd be a big switch from Timberwolf since they are both pretty rich, and admittedly I may have switched a bit too hasty, but I'm about to give up soon. I've also noticed that the bits of vegetables in it (carrots, peas, etc) don't seem to be digested at all. In one way, out the other! I don't know what's going on. I really like the Merrick brand but not having luck
