Bakers is probably one of the worst puppy foods out there but also one of the most widely available so understandably a lot of owners use it and while some dogs will be fine on it, others are not - the quality of ingredients is quite poor (very little real meat content) and it also contains artificial colours & preservatives. I would investigate better quality complete foods as you will probably see a huge improvement in your pup's "output" once you find a food that suits him. You'll find lots of recommendations for good complete brands if you have a read of this board 
As Jane s says it is very widely use...(Not to put a finer point Cheap)Contains feet and feathers and very poor value...Some dogs can get on with it were others dont..As Jane says(investigate better quality complete foods)...
