Louie's owner still feeds him Canidae, but he doesn't have an problems with the food as far as runny poos any no problems when the formula switched....is it still a pretty good food to feed since he isn't having any problems? I told him to switch to Kirkland, like I have since my dogs and other dogs had problems with the food, but I know the whole sign up with Costco thing can be expensive just for some dog food. What do you gusy think? Is it still ok to keep feeding Louie Canidae, since he's not suffering from any problems or to do the switch to Kirkland. I can get the food for his owner,whenever I go and get my dogs food at Costco....or maybe I can refer to him to the grain free Canidae formula if they offer it where he goes?
