Dog discovered to be holding bovine at far end of ranch (8)
I believe the answer is:
foxhound
'dog' is the definition.
(foxhound is a kind of dog)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for foxhound that I've seen before include "5 [MANS BEST FRIEND]" , "Hunting dog" , "hunter" .)
