Poppy was rescued by the RNLI after swimming to the beach
A springer spaniel survived a 300ft (90m) fall into the sea, after jumping off cliffs on the East Sussex coast to chase a seagull.
Poppy ran over the edge of the Seven Sisters cliffs at Brass Point during a walk, but managed to swim to shore and was picked up by a lifeboat crew.
The dog's owners, Kelly Ixer and Ben Markwick, from Ansty, said they were "indebted" to the lifeboat team.
Poppy was treated for a partially collapsed lung, but has now recovered.
She had been out walking with Mr Markwick's sister and her partner Stephen Winslade.
Mr Winslade, 31, said: "She ran to the edge and just disappeared.
"She is really well-trained and well-behaved, but I think she ran so fast there was no chance of her stopping.
"I threw myself down and looked over the edge and saw her paddling."
The RNLI was called out to rescue Poppy after her ordeal
