When I got my Shih Tzu, the previous owners were feeding her beneful. I switched her over to Iams, because I had heard it was a better food. Currently I have her eating Merrick's products (Grammy's pot pie right now). If I put down Iams, which I still have half a bag of, she won't go near it... at all! But as soon as the Merrick hits the floor (in a bowl, mind you) she is all over it.

Is Merrick a better food, or does she just like it better because it's something new and different than what she's used to?

Thanks,
Crystal
