Dog chewed slippers in anger (8,7)
I believe the answer is:
springer spaniel
'dog' is the definition.
(springer spaniel is a kind of dog)
'chewed slippers in anger' is the wordplay.
'chewed' is an anagram indicator.
'slippers'+'in'+'anger'='slippersinanger'
'slippersinanger' with letters rearranged gives 'SPRINGER SPANIEL'.
(Other definitions for springer spaniel that I've seen before include "breed of dog" , "might this be barking?" , "one used to raise game" .)
