The moment a dog falls out of a moving car and gets DRAGGED by its leash along a motorway

Shocking footage of a dog tumble out of a moving car and get dragged by the neck on its lead has been captured on video.
The unsuspecting canine can be seen leaning out of the window, clearly enjoying the wind in his ears and sniffing the air.
The dog leans a little further out but he has not anticipated the upcoming bend in the road.
As the car rounds the corner the poor pooch looses his balance - and tips right out of the car.
But the dogs leash wrapped around its neck is clearly secured within the moving vehicle.
For a few horrifying moments the dog is dragged along the motorway and comes perilously close to the car's crushing wheels.
The driver then realises what has happened and quickly pulls over to save the dragging dog.
The dashcam footage was captured on a motorway in London in 2015.
It is not clear how badly the dog was injured in the accident but it seems to be moving when the car stops which may herald some hope for its survival.
Prior to the accident, the dog was very intent on getting its head out of the car window and sniffing the air.
In the video, the dog looks like it may be a blood hound - a breed with an exceptional sense of smell which enjoy exploring their environment through smell.
Perhaps its leash had been so securely tethered in an effort to actually prevent him from falling out of the window in the first place.
According to the Highway Code, dogs and other animals should be suitably restrained so they cannot distract the driver or injure people in the vehicle, or themselves if the vehicle stops quickly.
A seat belt harness, pet carrier, dog cage or dog guard are some tools that can be used to restrain animals in cars.
