does he lay on alot of hard surfaces? or are there any other symptoms (dry skin, spots etc?) I know that my boy has lost his fur from his elbows due to having no bedding in his crate and laying on concrete in the garden! I don't know of anything to make it grow back thicker, but maybe if he is on hard surfaces alot try not to let him lye on them and get him on a blanket etc for a bit more protecton.
