Dog, red as the evening sun? (6)
I believe the answer is:
setter
This might be a double definition.
'dog red' is the first definition.
'setter' can be an answer for 'dog' (setter is a type of dog). I am unsure of the 'red' bit.
'the evening sun?' is the second definition.
(I've seen this before)
'as' acts as a link.
Can you help me to learn more?
(Other definitions for setter that I've seen before include "Breed of gun dog" , "Puzzle creator" , "A dog trained to stand still when it scents game" , "Dog found in street" , "Dog trained to point at game" .)
