Dublin-born compiler's flame-haired companion? (5,6)

Ross

I believe the answer is:

irish setter

I'm a little stuck... Click here to teach me more about this clue!

'flame-haired companion?' is the definition.
I can't tell whether this definition defines the answer.

'dublin-born compiler's' is the wordplay.
'dublin-born' becomes 'irish' (I've seen this in another clue).
'compiler' becomes 'setter' (both can mean a writer of crosswords).
'irish'+'setter'='IRISH SETTER'

Can you help me to learn more?

(Other definitions for irish setter that I've seen before include "Kind of dog" , "best friend" , "Breed of dog" , "Dog with dark red coat" , "Dog from the Emerald Isle" .)

I've seen this clue in The Telegraph.
