Let's work on this from a different angle: what's your budget per month for dog food?
If you can afford it and/or have time to feed something more complicated, I wouldn't feed dry kibble at all, as there are so many better options.
At the top of the line, if money isn't a constraint, there's Ziwi Peak or commercial HPP raw. Below that, there's dehydrated, minimally processed human-grade food mixes (like The Honest Kitchen, or even Sojo's), as well as base-mixes for adults (designed to be fed with raw to make a complete meal (like Dr. Harveys, The Honest Kitchen, Sojo's, and Balance It). I would put freeze-dried raw nuggets like Nulo in this ultra-high end category too. With any food in this category, you're probably looking at about $200/mo. (or possibly more) for dog food.
Then you can get into high-end kibbles costing nearly $100 per relatively small bag. And then gradually scale down to the mid-grade-but-quite-decent kibbles that are around $40-50 for a big 40# bag. That's about as low in price as you're likely to ever see recommended here, but there are a lot of fine options in between those price points.
Dog food quality falls on a spectrum, from utterly unacceptable to absolutely stellar, and most of it is somewhere in the middle. Kibble is a compromise of convenience and price.
So....what's your budget? When we have an idea of how much you comfortably plan to spend on food, we can tell you brands we've fed in that price range that feed out well.
