How food motivated is this dog ? Can you try to feed him by hand? So when your dog is hungry, try sitting on the floor with the bowl, and take a small bit of food out and offer it to the dog. (stinky canned food is good for this, although very messy, or some pieces of cooked chicken). Don't make eye contact, keep your body relaxed, don't be threateing, go slow. Just do this with one family member at first.
If you can get the dog to eat out of your hand, he will realize that people mean Good Things.
If he won't eat out of your hand, then try putting the bowl down and sitting nearby, then slowly try decreasing the distance as he's comfortable. Don't look at the dog, keep calm and quiet. The idea is to teach the dog to relax and that Good Things happen when he's near you.
Also, this dog has lived in a kennel with not a lot of contact for 6 years of his life. Change may take longer than a month.
