I have my boy (130lb Swissy) on BARF. We switched to it after being on ProPlan for 2 years for various reasons. The barf diet can sounds intimidating, but it is no more trouble than adding extras to kibble. I had thought about feeding an all-natural "raw" kibble, but it would end up costing me much more.
I buy my chicken at the grocery store (from 19 cents/lb to 39 cents/lb), and make my own veggie mix (whole eggs, pumpkin, spinach, strawberries, bananas, carrots,collard greens,a little garlic, etc..). I usually mix it with yogurt, a can of fish or ground meat, along with raw oats or rice. One batch of mix costs about $5, takes less than an hour to make, and lasts for about 3-4 months. It costs me roughly 30-40 per month to feed my boy (gets about 2.5 - 4 lbs a day). This is including cod liver oil, coat supplements, kelp, flax seeds, apple cider vinegar, honey, probiotics, and other misc things.
If anyone is interested, Natural Balance does have a raw food out now. It is only currently available in California and Neveda.
