Trials here to get dog speaking? (10)
I believe the answer is:
laboratory
'trials here' is the definition.
'get dog speaking?' is the wordplay.
'get' is a charade indicator (letters next to each other).
'dog' becomes 'lab' (short for labrador).
'speaking?' becomes 'oratory'.
'lab'+'oratory' is 'LABORATORY'.
'to' acts as a link.
(Other definitions for laboratory that I've seen before include "Where litmus paper could be" , "Language-learning facility" , "Place for experimentation" , "workplace" , "Where one investigates" .)
