Doglike scavenger (5)
I believe the answer is:
hyena
'doglike scavenger' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hyena that I've seen before include "Its howl sounds like laughter" , "Dog-like nocturnal mammal of Africa and southern Asia" , "Dog-like carrion eater" , "one to laugh" , "Carrion-feeding carnivore" .)
