Ivan-
I think it’s a good idea to rotate food. I try to rotate kibble, but I definitely rotate toppers every meal. I think variety is important. I also think it is very important to add fresher type foods to kibble to boost its nutrition as kibble is the least healthy, but the most convenient and affordable. I add canned to every breakfast. To their evening meals, I add either eggs, sardines, dehydrated, raw or lightly cooked fresh meat. I feed mostly Victor kibble, but you could print the 4 or 5 star list of foods and bring with you to your store to see what they carry and fits your budget. You will probably have to transition slowly if they have eaten the same food for a long time to avoid digestive upset. Also, some plain canned pumpkin or probiotics and digestive enzymes may also help with the transition until they are fully adjusted. I’ve seen a noticeable difference in my dogs’ coats since I’ve started the sardines and eggs. Good luck!
