Brendan and his dog? (5,6)
I believe the answer is:
irish setter
This clue could be a double definition.
'brendan and his' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'dog?' is the second definition.
(Irish setter is an example)
(Other definitions for irish setter that I've seen before include "Breed of dog" , "Dog with dark red coat" , "Dog from the Emerald Isle" , "best friend" , "Kind of dog" .)
