Cry upon sighting a fox (5-2)

I believe the answer is:

tally-ho

(Other definitions for tally-ho that I've seen before include "Huntsperson's cry" , "Cry of the huntsman pursuing the fox" , ""I've seen the fox!"" , "Hunting cry when a fox is sighted" , "Come on, hounds!" .)

I've seen this clue in The Guardian.
