Aww she's adorable.. I found the pictures on your profile.

Well I'd say feed her what the bag says, unless she's not finishing it all at once. If she doesnt finish, then I'd cut back.

I feed Nature's Recipe (Fish & Potato)... Eli gets 2 cups twice a day, Bunny gets 1.75 cups twice a day and Zeke gets 1.5 cups twice a day. Theyre all older than Sin though, as Eli is about 2.5 yrs, Bunny is about 5 yrs and Zeke is about 6 yrs. Even at 5 months though, we didnt feed Eli that much though.

I work from home too, and like to keep ours on a schedule. And of course, Zeke would eat until he blacked out... so we can't free-feed. Rescue dog mentality I guess.
