Tigers are ambush predators specialised for taking down singular, large animals, so the tiger would be somewhat out of its comfort zone here. On the other hand, chihuahuas, while very vocal, are not remotely trained or bred for violence. I could well imagine the tiger running out of stamina, but I couldn't imagine the chihuahuas effectively capitalising on this weakness -- even against an incapacitated tiger, they would have difficulty landing any kind of killing blow. I would be inclined to give it to the tiger.
