Hello, when I got my german shepherd puppy at 8 weeks the breeder had him on loyall puppy food, he is now 12 weeks and I am transitioning him to farmina lamb and blueberry puppy. The soft stools started happening about halfway through the transition and I am testing out 100% farmina at the moment. I even add in 1 to 2 tablespoons of canned pumpkin and he still has soft stools. I give him 1 cup 3 times a day. Is the food too rich for him, did I transition to quickly, am I giving him too much food…?
