He needs time to adjust. Remember, most likely this dog won't know anything other than a kennel and a racetrack. Talk to him gently and don't rush him. When he does go, make a fuss (not overly so, you don't want to frighten him more!), and gradually he will calm down.

I know what you're going through, when we first got our greyhound girl it took about an hour and a half to get her out the car, and days for her to come outside. She got there in the end though, and it was so rewarding!
