Your dog just needs some TLC and you'll get along just fine. Make it a habit to feed him and give him treats when he responds to commands, or even requests, and you can be sure he'll love you. If he hasn't tried to bite, then I would say he loves you already. Take him out for walks and talk to him a cool manner; you can also smile at him.
Spend time with him, all he wants is your time! Do things together, throw a tennis ball for him, when he brings it back, wet the tennis ball in cool water, then throw it for him, as the ball bounces, the dog gets sprayed with the cool water. I had a dog who loved that!
