Crossword Genius

Dog chewed up grannie’s slipper (8,7)

Ross

I believe the answer is:

springer spaniel

'dog' is the definition.
(springer spaniel is a kind of dog)

'chewed up grannie's slipper' is the wordplay.
'chewed up' indicates anagramming the letters.
'grannies'+'slipper'='granniesslipper'
'granniesslipper' 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" .)

I've seen this clue in The Times.
