"Beetle Bailey” dog (4)
I believe the answer is:
otto
'beetle bailey dog' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for otto that I've seen before include "- - Preminger (films)" , "-- Klemperer, conductor" , "Reversible German" , "Possibly a German" , "he goes" .)
