Dog, less about looks (5)
I believe the answer is:
ogles
'looks' is the definition.
(ogling is a kind of looking)
'dog less about' is the wordplay.
'about' indicates the answer is hidden within the clue (the clue goes around or about the answer).
'OGLES' is hidden in the letters of 'dog less'.
(Other definitions for ogles that I've seen before include "Leers" , "Looks at (someone) lecherously" , "Casts amorous glances" , "Looks longingly at" , "Looks at amorously, makes eyes at" .)
