Hound in the evening sun? (6)
This clue is a double definition.
'hound' is the first definition.
(thesaurus)
'evening sun' is the second definition.
(the sun sets in the evening)
'in the' acts as a link.
(Other definitions for setter that I've seen before include "A dog trained to stand still when it scents game" , "Dog trained to point at game" , "Bird trained to scent game" , "Mike of this parish, say" , "Canine" .)
'hound' is the definition.
(I know that Red Setter is a hound)
'in the evening sun' is the wordplay.
'in the' becomes 'red' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'evening sun' becomes 'setter' (the sun sets in the evening).
'red'+'setter'='RED SETTER'
Can you help me to learn more?
(Other definitions for red setter that I've seen before include "My best friend" , "Gun dog" , "Pet" , "Shepherds are delighted to see this" , "Breed of dog" .)
