Female dog we held back in entrance (7)
I believe the answer is:
bewitch
'entrance' is the definition.
(synonyms)
'female dog we held back in' is the wordplay.
'female dog' becomes 'bitch' (I've seen this before).
'held back' is a reversal indicator.
'in' is an insertion indicator.
'we' back-to-front is 'ew'.
'bitch' going around 'ew' is 'BEWITCH'.
(Other definitions for bewitch that I've seen before include "add glamour" , "Fascinate - charm" , "Get intoxicated" , "intrigue" , "Entrance" .)
