Coastguards were called to help free two horses trapped in mud at Brean Beach in Somerset at the weekend.
The horses sank to the tops of their legs as the sand gave way
The animals were being walked on Sunday by their owner Carol Brown, when a thin layer of top sand gave way and both sank to the tops of their legs.
Ms Brown, from Malmesbury in Wiltshire, said: "They were both distressed and we had a real struggle on our hands with the tide coming in."
The horses were freed just before the rescue services arrived.
"It was a real heart-stopping moment," said Ms Brown.
"They were stuck fast in the mud and we were worried. I'm just so glad it all ended happily. Both the horses, Ben and Tiggy, are very precious to us."
The incident happened just a few hundred metres from where a Land Rover car became trapped in April.
