Awww, what a sweetie he is
Very cute little guy! I would definitely start feeding him an 1/8 cup/day. It won't look like hardly anything at all once you get it measured out, but it WIL be enough food for him
As far as treats go, I would cut out
all commercially prepared treats and just give fresh fruits and veggies as treats. Bully Sticks are great chews to give....and don't add alot of calories like the treats do. These are also great to give and it keeps them busy
