Dance and Journey eat raw. Mostly ground premade, various brands and proteins. Quite a few RMBs too. And if I forget to thaw something then I have a few different things at home they can eat. Either the Dobermans' kibble (whichever they happen to be eating), Ziwipeak or NRG usually. I also have a small bag of Acana Duck & Pear for Journ just in case (it's the only kibble right now that I've tried that she can eat more than two meals in a row of with no problem - she used to have a super strong digestive system. Not sure what's happened in the last couple of months, so she gets a probiotic now too).
Ripley and Keira have no choice but to stay on a fish diet. As soon as I take them off of fish, even for one bag of food, within a week their skin gets really awful and they start getting yeasty smelling again. So, while I work where I do, they're eating mostly Orijen 6 Fish and doing super well on it, but I've also fed them Acana Pacifica, NV Instinct Salmon and Timberwolf Ocean Blue. I do add raw to their kibble sometimes though, or canned food of different proteins. They appear to do best on the Orijen of all the kibbles I've rotated through so far.
