Raw feeder here. I budget $1.30 per pound and with 3 dogs it all amounts to the same as Blue Buffalo.
If I have to go kibble, I would go with Blue Buffalo Wilderness or Earthborn Holistics Primitive Natural as they are most accessible. Fromm is also a good one but harder to find. You can get it from petflow.com and if you use ENGLISHBULLDOGS (if that doesn't work try it without the S) in the promotion you can get free shipping for packages over 45 lbs. Yes, I have English Bulldogs who are one of the most finicky dogs as far as nutrition go.
And for whoever said something about dogs not being obligate carnivores... yes, they are not obligate carnivores but they are carnivores nonetheless. The difference between an obligate carnivore and a non-obligate carnivore is that an obligate carnivore cannot process non-meat food at all whereas a non-obligate carnivore can process non-meat proteins if that's the only opportunity presented but their physiology is optimized for meat. Or in simpler terms - a lion is an obligate carnivore and will die if there is no meat to eat, whereas a dog is a non-obligate carnivore and eats whole prey but if they can't find one, they'll make do with whatever protein they can find.
Now, very important words here - whole prey. If you only feed your dog ground beef and chicken legs you're not giving your dog whole prey and would then have a nutritionally deficient diet.
