But before you do that, see if you can fit Earthborn Holistics Grain-Free in your budget. It costs $50 for a 28-lb bag. Kirkland is $30 for a 40-lb bag. Big difference, I know. Earthborn is a quality estabilshment in about the same league as Fromm but cheaper than Fromm. They don't sell it at PetSmart though. They do sell it at petflow.com with the free shipping. If this is just not possible for you, I suggest going with Kirkland.
I got Bullied and loving it!
