I'd say these were two captive animals that got exploited for the sake of some film drama. You know, Marty Stouffer style.
Next question: Pitbull vs Wolverine?
I believe I've seen a longer version of this clip before, and what they were initially filming was a wolf finding a kill, who then got challenged by a wolverine who wanted to drive him off the kill. Wolf was determined to keep the kill, so a fight ensued.
The photographer may well have planted the kill, though, to attract some carnivores to it for filming.
