Riley weighs around 8lbs. He eats about 1/4 cup of food, total per day with a few treats throughout the day.
I have been feeding him about 1/8 cup of Primal premade raw in the mornings and then he and eats 1/8 cup of ACANA kibble at night.
I usually cut up a few frozen green beans and put a few peas in each meal. For the kibble, I will also let it soak in a little bit of water, for a few minutes, then drain, and sprinkle it with a tiny bit of Cocotheraphy Coconut Chips.
It took me a few months to get the food thing right but he is totally thriving now. People comment all the time about how great his coat looks.
Good Luck!
