Miner clipped dog (6)
I believe the answer is:
collie
'dog' is the definition.
(collie is a kind of dog)
'miner clipped' is the wordplay.
'miner' becomes 'collier' (collier is a kind of miner).
'clipped' means to remove the last letter (the word is shortened or clipped).
'collier' with its final letter taken off is 'COLLIE'.
(Other definitions for collie that I've seen before include "Popular kind of sheepdog" , "Sheep-herding dog" , "Type of sheepdog" , "See 2" , "Scottish sheep dog" .)
