CHANGE THE BRAND. you probably just have a picky eater. Snickerdoodle, my young male, was eating his pellets and then stopped, too. I immediately replaced the food type (this was a bad choice on my part, as such drastic changes in diet can cause digestive issues, but Snickerdoodle was fine, thankfully.). I feed CareFresh, and my chin loves it! He specifically adores the whiter pellets, so i feed those to him as a treat (obviously daily, because they're part of a complete diet). Try CareFresh.
