Frightening creature from which dog ran? (6)
I believe the answer is:
dragon
'frightening creature' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'which dog ran?' is the wordplay.
'dog ran' anagrams to 'DRAGON'.
However, I am not clear how this is indicated.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for dragon that I've seen before include "Intractable person" , "Fury" , "Virago" , "Mythical fire-breathing animal" , "Creature of Teutonic mythology" .)
