what to feed a 13 week great dane puppy

[fay]

Boy,have I been getting confusing info about what to feed a great dane puppy. I have spent lots of time reading labels on the dog food and on the web about great danes. Is it true the food must be: protein no higher than 24%, fat no higher than 14%? What about calcium? I am currently feeding her Chicken soup for dog lovers adult large breed as the protein is 23 and the fat is less that 14, so that is good. Any help in what food please help. I live in Canada.
Thanks
