Well, maybe you should consider a large breed formula, a dog that will grow to be 50 pounds or more is considered to be a large breed.

Maybe that is too much food? Don’t go by the amount recommended on the bag as it tends to be too much.
I am more familiar with small breeds, but I did have an adult 35 pound dog that got about 2 cups of food per day, otherwise she would gain weight.
Too much food can cause loose stools and diarrhea.
