Dog treat (7)
I believe the answer is:
biscuit
'dog treat' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for biscuit that I've seen before include "type of pottery?" , "Baked confection" , "Custard cream, perhaps" , "Rich tea, for example" , "Food (literally twice cooked)" .)
