The vet was supported by some Royal Marines, who were on exercise at a firing range close by.
Buddy was then placed in a trailer and returned to his stable.
“Christmas is saved thanks to some great work from multiple agencies,” Southport Lifeboat added.
Local Facebook group Formby Bubble shared a message from Buddy’s owners, posting: “We’re happy to report that Buddy is now safe, warm and snuggled up back home in north Wales.
“After his unexpected seaside adventure, he is enjoying some well-earned rest in his cosy stable and will be taking it easy for the rest of the year.”
