Kennel cough, heart worm and previously irritating the throat are the only things that come to mind. She could have slightly choked on something earlier that is causing a scratchy throat.
Or, if in contact with other dogs, she may have picked up kennel cough.
Heartworms go in/through the lungs - but not something you should worry about if you use regular preventatives on your dog and see a vet to be tested.
