Wanting perfect dogs at home (10)
I believe the answer is:
incomplete
'wanting' is the definition.
(I've seen this before)
'perfect dogs at home' is the wordplay.
'perfect' becomes 'complete' (perfect and requiring no additional changes).
'dogs' is a charade indicator (letters next to each other) (dogs can mean follows or chases).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'complete' put after 'in' is 'INCOMPLETE'.
(Other definitions for incomplete that I've seen before include "Lacking" , "Wanting" , "Not whole" , "not done" , "Inadequate" .)
