Sweet dog from Oliver Twist (8)
I believe the answer is:
bullseye
'sweet' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bullseye that I've seen before include "Gold" , "A sucker" , "What may regard rival stock" , "Dead centre - Bill Sikes's dog - sweet" , "window" .)
