Piece of cake kennelling stray dog (7)
I believe the answer is:
terrier
'dog' is the definition.
(I know that terrier is a type of hunting dog)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for terrier that I've seen before include "Dog - army volunteer - land register" , "Reserve soldier" , "Small, originally burrowing, dog" , "Small, active breed of dog" , "Breed of dog - volunteer soldier - estate register" .)
