Barker is looked after by this kind of maid (6)
I believe the answer is:
kennel
'barker is looked after by this kind of maid' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
This is all the clue.
Can you help me to learn more?
(Other definitions for kennel that I've seen before include "A dog's home, usually outside house" , "housing for boxer, say" , "Dog's shelter" , "Canine boarding place" , "Dog shelter" .)
