Turn pets out, distressed (5)
I believe the answer is:
upset
'distressed' is the definition.
(I know that distressed can be written as upset)
'turn pets out' is the wordplay.
'turn' becomes 'u' (a 'U-turn' is a kind of turn).
'out' indicates an anagram (out can mean wrong or inaccurate).
'pets' with letters rearranged gives 'pset'.
'u'+'pset'='UPSET'
(Other definitions for upset that I've seen before include "Disturb(ance)" , "emotional" , "Unexpected sports outcome" , "Disturbed or knocked out of place" , "Overturn; distress" .)
