I did so much research and finally decided that a raw meat diet was the best choice, both for my dog's health and my wallet. I use (loosely) the Prey Model Raw
diet and have seen amazing results. To get the best prices on meat, you have to have a place to store meat bought in bulk (like a chest freezer), but I found mine on Craigslist for $20. Please let me know if this is something you're interested in, because I know of a lot of helpful resources. Raw feeding is growing in popularity because of its amazing health benefits, and there are so many forums and sites for advise.
If this isn't a route you want to follow, at least visit Dog Food Advisor
to compare dog food brands. You would be shocked at the terrible ingredients dog food manufacturers are allowed to use. Dr Karen Becker also does a couple really good videos on choosing a commercial dog food: link
I'm realizing after writing all this that you may not actually be looking for advise. But here's my answer anyway
