At times nature can be cruel, but there is also a raw beauty, and even a certain justice manifested within that cruelty.
Note that the Alpha dog has a muzzle hold on the croc, preventing it from breathing, while another dog has a hold on the tail to keep it from thrashing. The third dog attacks the soft underbelly of the reptile.
Not for the squeamish...
