Predatory canines (6)
I believe the answer is:
wolves
'predatory canines' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for wolves that I've seen before include "'Predatory canines, they hunt in packs (6)'" , "Vowels for lupine creatures" , "Canine animals" , "Vowels of wild canines" , "Eleven" .)
