The Sabertooth was the disguise of a real live tiger.
It appeared to be a sabertooth tiger with long fangs.
It was a wild animal. It proved to be less fierce than the feral cats also roaming the preserve.
Scooby-Doo! (DC Comics)
Mr. Farnham put fake fangs on a tiger to create Sabertooth, to drive Mr. Herriot off the land so he could reclaim it and then sell valuable prehistoric artifacts and fossils that were preserved in a cave on the land. (It's Always Feral Weather)
