Dog's way to get in trouble with the RSPCA? (7)
I believe the answer is:
whippet
'dog's' is the definition.
(whippet is a kind of dog)
'in trouble with the rspca?' is the wordplay.
'in' indicates putting letters inside.
'trouble' indicates anagramming the letters.
'the rspca?' becomes 'ppe' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' is an anagram of 'whit'.
'whit' going around 'ppe' is 'WHIPPET'.
'way to get' acts as a link.
Can you help me to learn more?
(Other definitions for whippet that I've seen before include "dog class?" , "Small greyhound-type dog" , "Racing-dog" , "Greyhound relative" , "racing animal" .)
