My dog? (6)
I believe the answer is:
setter
'my dog?' is the definition.
(setter is a type of dog)
This is the entire clue.
(Other definitions for setter that I've seen before include "Dog found in street" , "who is giving you problems right now?" , "Late evening sun is a" , "Thematic type [DOG]" , "Crossword maker; dog" .)
