I just started my 3 month yorkie on Natures Variety. He is a very picky eater. I tried feeding him Orijen, Artemis, Eukanuba, etc. He did not eat the dry kibble unless he was very hungry or unless I hand fed him. I decided to switch to the raw diet using Nature's Variety and he ate it in seconds. I am on week 1 1/2 and he is doing very well with eating raw. Now I am concerned with how much to feed him. I have the NV medallions. Since I work during the day...I feed him one in the morning, I leave 1/4 cup of dry kibble out (sometimes he eats it sometimes he doesn't), and then I feed him one medallion around 7 or 8pm. Am I over feeding him? He is only 2.5lbs. Please advise
