Doesn’t do it, being pro-animals (8)
I believe the answer is:
forbears
'doesn't do it' is the definition.
I can't judge whether this definition defines the answer.
'pro-animals' is the wordplay.
'pro' becomes 'for' (I've seen this before).
'animals' becomes 'bears' (bear is a kind of animal).
'for'+'bears'='FORBEARS'
'being' is the link.
Can you help me to learn more?
(Other definitions for forbears that I've seen before include "doesn't!" , "Refrains or abstains from" , "Keeps in check" , "Desists" .)
