The photographs were taken by 27 year-old Peter Bailey from Tenby who was walking his dog along the beach on Friday evening.
He told the Western Telegraph: "I was taking my dog for her evening walk across the south beach when she started acting out of character by howling and running round in circles.
"I ran up to her to see if she was ok and then I came across this hideous looking carcass. I could see it had little hair left on it's decomposing body.
"Immediately I thought it was a horse but it had claws like a bear and a body of a pig. Surprisingly it didn't smell."

when a similar one washed on a USA bearch they said it was a racoon, but it looks a bit too mostrous for a racoon to me
