Im transitioning both of my chi's to it. And i tell you, size comparision to other small breed foods such as blue, wellness core sm breed has very tiny kibbles! My chi's are doing fine with it so far and they seem to like it a lot too. You should try diff kinds of kibbles with diff meat meals, if they eat perhaps a chicken meal kibble for a very long time, they can develop allergic reaction to chicken meal based kibbles but yes i think wellness core sm breed is a good food, other wellness core kibbles are good too, i kno a lot of people here feed it to their chi's too. It is totally up to you.
One more thing, i also like the sm breed core version more because it contains glucosamine and chondroitin. Here is the ingredients:
