I'm right there with you with the runny eyes. My girl was a year old Jan. 25th. From puppy we too have switched foods alot because she would just stop eating it.
She has now been on the new Buffalo for small breed and she is loving it. I also use about a half teaspoon of their can food with it. I take the can food and microwave for 6 seconds stir in the can and feed her immediately. She actually dances in circles all the way to the sunroom to eat! YAY!!
