Maximo eats Acana. He weighs 8 lbs, 4 oz and is active. The extra 4 oz came after he started eating Acana.
Anyway, he eats less than 3/4 cup a day. I use a 1/4 cup scoop and I don't fill it to the top for his 3 meals per day.
I also give him a few sweet peas and 2 teaspoons of yogurt per day. Chew bones are his only treats.
