Cheeky retriever bounding around end of garden (10)
I believe the answer is:
irreverent
'cheeky' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for irreverent that I've seen before include "Cheeky" , "Disrespectful" , "Impious" , "Not respectful" .)
