I had this same question when we first brought Berkley home, we just went with what the manufacturers recommended. We mix in canned food with every meal. When she first came home, she wouldn't touch dry kibble, so we kinda had to mix it to get her to eat. We started her on Nutro, and their canned food is chunky with a "gravy", so it moistened the kibble. However, now we are switching her to Canidae, and their canned food is more solid, no gravy to it at all, but she seems to like it. Canidae recommends 75% kibble, and 25% canned. We occasionally give her some yogurt, or an egg, to switch it up, but she still won't touch straight kibble. We get about 4-5 meals per can, and its only about $1 per can, so it doesn't add much to the cost. In the long run, I hope to get her off of canned food, but i guess thats kinda up to her...lol.
