Vet show on television? (6)
I believe the answer is:
screen
I believe this clue is a triple definition!
'vet' is the first definition.
(I've seen this before)
'show' is the second definition.
(screen can mean to show a film)
'on' is a link.
'television?' is the third definition.
(thesaurus)
(Other definitions for screen that I've seen before include "Protect or conceal" , "Set of foldable hinged panels" , "Conceal; show (a film)" , "Show pictures on the surface" , "Protective frame" .)
