We tend to feed the grain-free formulas (Lamb & Lentils being the one we feed the most) but the grain-inclusive are also good...we're just now starting a bag of the Whitefish and Potato. I think many of the formulas are similar composition-wise (aside from the featured protein source and kibble shape sometimes) so that's why they say that rotating various formulas can be done without any issue if you want (we don't get through bags quick enough to have more than one 4-5 pound bag of food open though). |
