Sometimes Major (almost 1 yr old!) will eat three times a day and then sometimes just once. I was wondering if it is ok to switch food brands every bag or every two bags? He had Wellness and after a few months he wouldn't eat with the same enthusiasm, so we switched to the Nutro and now after a few months we are having the same problem. I don't want to cause any gastro intestinal problems by constantly switching food if that would be the case.
