Miner runs out for dog (6)
I believe the answer is:
collie
'dog' is the definition.
(collie is a kind of dog)
'miner runs out' is the wordplay.
'miner' becomes 'collier' (collier is a kind of miner).
'runs' becomes 'r' (cricket abbreviation).
'out' indicates named letters should be taken away.
'collier' with 'r' taken away is 'COLLIE'.
'for' is the link.
(Other definitions for collie that I've seen before include "Type of sheepdog" , "Sheepdog wth ling nose and shaggy hair" , "Working animal" , "shepherd's gofer" , "Scottish sheepdog" .)
