You know, with everything going on maybe you need to find an experience working home for him. I'm not one to suggest re-homing a dog, but you're REALLY going to be in trouble with this dog soon if something dramatic doesn't change. Since you're obviously dependent on your parents, and their lives seem rather busy with other things right now... it seems like this would be in the dog's best interest. He needs LONG walks right now. He needs LOTS of interaction, and he's just not getting it. The combination of your age, family status, and lack of experience, it just sounds like the wrong dog at the wrong time. Did you get him from a breeder? If so, I'd contact the breeder.
