The dog, a white Staffordshire bull terrier, was hit by a vehicle passing by the Common on the B1041 and left in the road. Gavin Childs-Brown was driving home in the car behind at around 5.30pm when he saw the dog, and stopped to try to help. He said: I noticed the dog in the road you couldnt miss it. She was still alive, and the cars bumper had been left by the side of the road as well. There was a person across the road who said he had seen the collision, and he said it was the car in front of me. Mr Childs-Brown, the dogs owner and other passers-by tried to help, but her injuries were too serious and she died minutes later. Mr Childs-Brown, of Skipper Way, Little Paxton, is now asking the driver who hit the dog to come forward. Firstly, I just hope that the person who did it realises that it is the law to stop, and secondly, I hope they come forward. I understand they might be in shock, but if it had been me I would have got to the end of the road and turned back. It probably wasnt the drivers fault, but I would have come back to say sorry at least. But the driver left it for someone else to sort out.
