A dog was killed after being thrown from a car onto a busy motorway on Father’s Day.

The dogs were wrapped inside a blanket when he was hurled onto the M25 at around 6.30pm yesterday (Sunday) between Junctions 20 and 19, for Chandlers Cross, Abbotts Langley and Leavesden.

Cars going at around 60mph were forced to break and swerve to avoid a Jack Russell and a Lurcher, the latter was hit by numerous vehicles and died instantly.

The Jack Russell, nicknamed Tarmax after his rescue, managed to dodge the slowing traffic and made it to the side of the road, with a number of drivers pulling over to help.

RSPCA animal welfare officer Peter Warne said: “This is an absolutely outrageous thing for someone to have done.

“The danger that this act put not only the dogs in, but also the many people traveling on the road at that time, is just appalling.”

The RSPCA have said have so far not got a clear description of the vehicle that the dogs were thrown from.

This has led to an appeal for any witnesses on the M25 at that time to come forward.

Peter Warne added: “It is terribly sad the Lurcher did not survive and was killed in such a horrific way.

“It seems this poor dog’s death was instant due to the speed that the vehicles were travelling at.

“However, I’d like to say big thank-you to those drivers who were able to safely slow down and help to catch the dog, and the person who waited with him until I arrived.

“Those people almost certainly saved this dog’s life.”

Tarmax is believed to be six or seven and suffered no injuries, it’s also been discovered he was not microchipped.

Tarmax is now safe and is being moved to a temporary foster home under the care of the RSPCA.
