Go out and buy the best dog food that you can afford... then you can feed healthy leftovers and eggs with the kibble, to supplement it. That will make the dog food last a lot longer, and it will be so much better for your dog. It's essential that he gets all of the nutrients he needs, and any AAFO approved dog food, even really low quality food provides that. You can buy a 30 lbs of dog food for $10. If you do not have $10, surrender the dog to a shelter and take care of yourself!
