Rewards for Rover (6)
I believe the answer is:
treats
'rewards for rover' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for treats that I've seen before include "Entertains someone at own expense" , "Entertains at one's own expense" , "Entertains with taters" , "everyone likes them" , "doctors" .)
