Citizen of one South Asian country; large dog (6)
I believe the answer is:
afghan
(Other definitions for afghan that I've seen before include "Eg, native of Kabul; blanket, shawl" , "Tall breed of hound with a long silky coat" , "Tall thin hound with long silky hair" , "Native of an Asian republic" , "Tall, graceful hound with silky coat" .)
