Neurotic dog did this to sheep? (7)
I believe the answer is:
worried
'neurotic' is the definition.
Both the answer and definition are adjectives. Perhaps there's a link between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for worried that I've seen before include "Felt or caused to feel anxious or troubled" , "Was unduly anxious" , "far from calm" , "Apprehensive" , "Concerned, anxious, troubled" .)
