When determining the expense of dog food, I strongly encourage you to "do the math." The higher quality kibbles appear to be more expensive, but they really aren't. The cost of the individual bag is higher, but there aren't any fillers and your dog will eat much less of it, and the bag will last much longer than the crappy, cheap stuff. In many cases, the high quality food is cheaper per day than the crappy stuff.

When you can feed the best and actually save money (and probably have fewer health problems & lower you vet bills, too), it's a win-win. Good for your pocketbook and good for your dog.
