Horseshoer (7)
I believe the answer is:
farrier
'horseshoer' is the definition.
(I know that horseshoer can be written as farrier)
This is the entire clue.
(Other definitions for farrier that I've seen before include "Blacksmith who shoes horses" , "Specialist blacksmith" , "Shoemaker" , "Veterinary surgeon" , "Felix Randal's job (G. M.Hopkins)" .)
