Very many dogs not needing lead (6)
I believe the answer is:
oodles
'very many' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for oodles that I've seen before include "Tons, scads" , "wealth" , "Loosed among lots" , "Lashings, loads" , "Plenty" .)
