If it were my dog, I would have tried to move the snake before something like this occured, however, once the dog was in the snakes possession there is no way I would have even touched the snake. Remember, this is a VERY large animal, not only would the dog have been dead before you could have done anything about it, but the snake could have very easily strangled or suffocated a human in minutes. This was a wild animal doing what wild animals do, eat. It doesn't matter if it's a cat, a dog, or a child. They will find something to eat and eat it. One animal died already in this situation, what purpose would killing another do? What gives the dog more right to live than the snake? I understand it is a pet, but the dog would have been far gone by the time anyone could have done anything. Much smaller snakes take about 3 seconds to kill their prey, not nearly enough time for a human to wrestle the pet away.

The fault was not the snakes, but the dogs owners. They should have relocated the snake as soon as they noticed it was hanging around.
