Jackson is a healthy, active, 15'lber and he eats 1/2 cup total per day of both Acana and Orijen. 1/4 cup in the AM, 1/4 cup in the PM. He also gets a little wet food mixed in.
If he is extremely active for the day, I may up it to 3/4 cup but he rarely wants to eat that much. Acana and Orijen are very calorie dense so less food is necessary.
