Lick, like a dog (3)
I believe the answer is:
lap
'lick like a dog' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lap that I've seen before include "Once around the course" , "One circuit of a course" , "Knees" , "Once around the track" , "Scoop up with the tongue" .)
