Old yeller? (5)
I believe the answer is:
crier
'old yeller' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for crier that I've seen before include "Officer making announcement" , "Official making proclamations" , "The town . . . used to shout oyez" , "Old-time announcer" , "Town's announcer" .)
