Crossword Genius

Lots of dogs pee in the auditorium unobserved (6)

Ross

I believe the answer is:

oodles

'lots of' is the definition.
(I've seen this before)

I can't explain the rest of the clue.

(Other definitions for oodles that I've seen before include "wealth" , "A great many" , "Very great amount (colloq.)" , "Plenty" , "Informally, great quantities" .)
