Dog is a clue (7)

Ross

I believe the answer is:

pointer

I believe this is a double definition.

'dog' is the first definition.
(I know that pointer is a type of gun dog)

'a clue' is the second definition.
(thesaurus)

'is' acts as a link.

(Other definitions for pointer that I've seen before include "helpful tip!" , "Game dog, used for its ability to scent" , "Arrow" , "Suggestion" , "under control of mouse" .)

I've seen this clue in The Daily Express.
