Guard dog (7)

Ross

I believe the answer is:

mastiff

(Other definitions for mastiff that I've seen before include "Strong breed of dog" , "Hound" , "Powerful dog breed" , "Large short-haired dog breed" , "Large, powerful, short-haired dog" .)

I've seen this clue in the Sydney Morning Herald and The Telegraph.
