I wouldn’t recommend any of the foods you’ve listed. Canidae and Blue Buffalo are both Diamond brands, who is know for terrible quality control and equipment repair, and Innova (along with EVO and Califorina Natural), are owned by Mars, who also makes brands such as Pedigree and Iams, and of course, human candy bars.
What I do recommend is that you head over to the Diet and Health section, and check out the Large and Giant Breed Puppy Food list. These are all reputable brands that all contain the proper amounts of calcium and phosphorus for growing large breed puppies. The most up to date list is near the end of the thread.

Good luck with your new puppy! Post some pics, too! I love Afghans 🙂
