I feed my 3 dogs natural balance

We feed ours Diamond brand dog food. They have one made for small dogs.

Royal Canine specifically for Yorkies

we feed our yorkies "Earthborn Holistic" primitive natural. it's grain/soy/bi-product free. and our little guys have done so well on it since we switched from beneful. we use primitive natural kind becuase we also feed two big dogs and a diabetic ferret on it. so we need this kind, but you should probably go with the small breed kind, just google earthborn holistic and check out their website. it really is good stuff

Canidae, innova, and solid gold are just a few of the top dog foods. We feed our small dogs (a Maltese and chihuahua) solid gold. It's great, and I'd highly recommend it for small dogs like your yorkie.

royal canin. that's what I feed my 7 month old yorkie

I have a Yorkie too-he's very very sensible! He eats Royal Canin Mini Adult and he really likes it. Sometimes, I add some cheese, or apple!

Hope that helped
PS: He is 7 years old and he's very active, happy and healthy (he eats Royal Canin everyday)
