There is an emergency clinic in Savannah. Its closer than Charleston. Other than that i would call Buckwalter Vet in the a.m. They should tell you to come right in. I am so sorry he is in pain.
You can drive him to a 24 hour Specialized Animal Hospital in Charleston or - if you think you can hold till morning, I suggest you call Bluffton Veterinary Hospital at 8am and explain your dog's problem. They are super nice, very good and have a large number of vets. I believe they will say to come on in. I am sorry your dog is hurting and wish you the best of luck.
