Guide disturbing vet again (8)
I believe the answer is:
navigate
'guide' is the definition.
(I know that navigate is a more specific form of guide)
'disturbing vet again' is the wordplay.
'disturbing' indicates an anagram (I've seen this in other clues).
'vet'+'again'='vetagain'
'vetagain' with letters rearranged gives 'NAVIGATE'.
(Other definitions for navigate that I've seen before include "Plan route (eg, of ship)" , "Set (a ship's) course" , "Guide ship or aircraft" , "Move around while browsing the Internet" , "Move around a website" .)
