Query: The only dog food my dog will consistently eat

I have a stubborn chihuahua/daschund mix dog. Kibbles 'n Bits is the only dog food that he will eat with any degree of consistency. He actually prefers the mini-bits. (I guess size does matter.) I tried premium foods thinking they would be better for him, and, at most, I've only been able to get him to eat each brand once or twice.
