You could pick the dog up and take it to the free clinic near the parachute R/A. Alternatively you can contact QAWS, just search their name on this site.

As for the dog being thin, it is probably a saluki. They are similar to a grey hound and are used by the locals for hunting. These are th most common strays here also.
