A chestnut mare stranded in a fishing lake yesterday was rescued by firefighters and RSPCA officers.

The horse was spotted at 6.30am yesterday morning in a lake mare in Colney Heath, Hertfordshire. She was stuck in over four feet of mud and water and unable to move.

RSPCA officers believe the horse fell in while drinking.

Three RSPCA officers and firefighters attached a harness to the mare, who was shivering and in shock.

After much pushing and pulling, over two hours, the exhausted horse was finally dragged to the bank and treated by a waiting vet. She was also reunited with her hungry foal.

RSPCA animal collection officer, Sarah Lambert, said: “This was a very successful rescue and I’m glad that the horse and her foal are back together again.

“She must have been in the water for some time so we needed to get her out as soon as we could to prevent her from suffering further from the cold.”

The RSPCA are conducting further inquiries into the ownership of the mare after a scan revealed a microchip registered in France.
