Do poles trouble dogs? (7)
I believe the answer is:
poodles
'dogs?' is the definition.
(poodle is a kind of dog)
'do poles trouble' is the wordplay.
'trouble' is an anagram indicator.
'do'+'poles'='dopoles'
'dopoles' with letters rearranged gives 'POODLES'.
(Other definitions for poodles that I've seen before include "Dogs in old pose" , "Curly-coated dogs" , "Lackeys" .)
