My dog is shivering constantly on and off for the last few hours. He is crying constantly and very sluggish & antisocial which is not normal.

Poor pup! Shaking is a common sign of pain or discomfort in dogs, which could also cause him to be crying, acting lethargic, and not very social. Unfortunately, these are very vague symptoms that could be caused by almost anything, so it's hard to say what might be causing this without being able to examine him. Many dogs with back pain due to a pinched nerve or herniated disc will act this way, so this is certainly a possibility; he could also have abdominal pain, or some other type of injury that isn't visible from the outside. Since it sounds like he's very painful and the underlying problem may be serious, I would really recommend taking him to a vet right away - he/she can do x-rays or other testing if needed to help diagnose the problem and get him started on appropriate treatment.
