I recently switched my two from Merrick's to Canidae. I usually rotate every 4-6 months. I bought a bag of All Life Stages, and a bag of Lamb/Rice. Baxter eats basically everything with gusto, so he's no problem. Snickers is more fussy and I notice he prefers the Lamb/Rice. He needs to be coaxed to eat the ALS.
There were a couple of gurgly tummies the first few days they were on it completely, but that has since disappeared. I did notice that their poop is less smelly and they seem to go less often. Hope this helps.
