He is adorable! And welcome to YT! I have tried several types of kibble too. Yorkies can be one of the most picky eaters!

I still haven't gotten my Ahi to like one type of food. She refuses kibble. So I crush it and blend it in her wet food. She is on Evangers right now and even that she tends to turn her nose up at it. Good luck on finding something that he will love. Oh btw you will be able to join the Teapot club.
