i'd have to guess you'd do better adding an egg to their meal ...... if you fed them the whole container , in one meal , of the bully max you'd add an extra cup to a cup and a half of his dog food worth of calories ..... compare the nutritional information of an egg to that stuff .......... you could get a dozen eggs for .33 cents , it'd be 2x the calories in the entire container of that bully max stuff , I believe an egg is one of the most complete sources of protein there is ? you might want to hard boil it at least sometimes because of the avidin thing , but I don't believe it'd be an issue ...... those muscles and bulk they show on the dogs they advertise are genetic ........
