The alligator, one of the oldest and ultimate predators, normally considered the apex predator in its natural eco-system, can still fall victim to implemented team work strategy, made possible by the tight knit social structure and survival of the fittest pack mentality bred into canines over hundreds of years by natural selection.

Note that the Alpha dog has a muzzle hold on the gator preventing it from breathing, while the remainder of the pack prevents the beast from rolling.
Beware! This is not for the squeamish!
