Cold, injured and stranded on a train track for two days, this terrified dog faced certain death.
But thanks to her loving companion who faithfully protected her until help arrived, Lucy survived the horrifying ordeal.
She was too injured to move from the tracks in Ukraine but her male friend Panda kept her alive by curling up next to her and pushing her head down when trains zoomed over.
If locals in Uzhgorod came too close, then Panda barked to scare them away.
The pair were found by Denis Malafeyev, who shared a heart-racing video of the dogs dodging a train which sped over their heads.
Even after they were rescued, they remained snuggled together in car boot on the way to the vets.
Mr Malafeyev said it was unclear if she was injured after being hit by a train crossing the track.
He added: "It's such a touching story. I got a phone call from a friend who said that there were two dogs lying on the railway track near Tseglovka village for two days.
