Cujo versus Darkseeker dogs.....
Same scenario as "I am Legend." Except that Neville had Cujo as his dog, replacing Sam. Sam has contracted rabies and Neville doesnt know it.
Neville falls for the booby trap, Cujo goes ape shit barking, Neville cuts himself loose and is backing towards his truck, and the three Darkseeker dogs are set on them.
Neville doesnt make it to the truck, one of the dogs rips him to shreds.
Cujo's rabies kicks in as the three Darkseeker dogs circle him and the fight is on.
