Lots of dogs — no pressure! (6)
I believe the answer is:
oodles
'lots of' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
(Other definitions for oodles that I've seen before include "A great many" , "Large indefinite number" , "A lot" , "Loosed among lots" , "Very great amount (colloq.)" .)
