After nine years of yapping at crocs, it finally happened.A saltwater crocodile has eaten a dog that made a mockery of it for years, to the horror of onlookers who captured the scene on camera, who were at first herd to say "Start recording", very aware of the dogs actions to bark at the crocodile.At Goat Island Lodge, south of Darwin in the middle of the crocodile-infested Adelaide River, guests had gathered to watch dog Pippa (aka the Dumb Blonde Dog) perform her favourite trick — running at "Casey the Crocodile" to scare her back into the river.But to the alarm of those looking on, including owner Kai Hansen, Pippa ran straight at her head — and Casey "did what crocs do".The video of Pippa being dragged into the water was made worse by the screams of bystanders, but serves as a bleak warning about the river's dangers.As owner Mr Hansen conceded, "it was something that had a high probability of happening sometime".
