Success, yes, but the dog takes no bow! (3)
I believe the answer is:
wow
'success' is the definition.
(I have seen 'Huge success' mean 'wow' so perhaps 'success' could also mean 'wow')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for wow that I've seen before include "Expression of amazement" , "Exclamation of admiration - another palindrome" , "Great success" , "Palindrome exclamation of astonishment or admiration" , "Cor! - huge success" .)
