There are significant differences between these 2 choices. If you can't decide between them, you could always use both in a rotation.
I've never used k9Natural, but it appears to be a raw frozen diet, not an air dried diet. So it has to be kept frozen or refrigerated, where ZP does not. ZP has vitamins/minerals added to it while k9naturals does not.
k9natural contains fruits and vegetables. They have also chosen to add in blood to their formulas. Here's the ingredients on their lamb formula:

Lamb meat, lamb bone, lamb blood, lamb green tripe, lamb liver, broccoli, cauliflower, carrot, spinach (chard), cabbage, apple, pear, lamb hearts, lamb kidneys, eggs, green lipped mussel and garlic.
