Here's one I'd like to add:

Balanced Diet Premium Dog Food. I've tried Raw and a couple different dry dog feeds. My bulldog always had soft mushy stools and antibiotics worked for a short time for his overgrowth of bad bacteria in his gut. I didn't want to keep him on the meds. After receiving samples I was hooked. Shiny coat and hard stools like he's supposed to have. In fact I didn't even have to slowly transition him. It worked from the get go. I have him on the Exalt Sports Performance Moist Feed. It's consistency is like soft jerky. It smells up the whole room.
The owner Jon is a great guy to deal with. May be hard to reach by phone but responds to emails well.
