Burrowing animals — hounds or nags (7)
I believe the answer is:
badgers
This clue might be a double definition.
'burrowing animals hounds' is the first definition.
I know that 'burrowing' relates to this answer.
'nags' is the second definition.
(I've seen this in another clue)
'or' acts as a link.
Can you help me to learn more?
(Other definitions for badgers that I've seen before include "Burrowing mammals with strong claws" , "Pesters; black and white nocturnal animals" , "Bullies" , "Pesters like burrowing animals" .)
