Mark Woods put out a plea on social media asking friends and family to accompany him on one last walk with Walnut, his 18-year-old Whippet.
"Sadly I am having to have Walnut euthanized on Saturday 12th November and so we will be having a last walk together on his beloved Porth Beach at 9:30 a.m.," he wrote.
"I would love it if dog lovers/owners and friends would join us for a celebration of Walnut on his favourite Porth Beach," Woods continued. "He has had an incredible life and having reached the grand age of 18 is ready for his final sleep."
Woods got even more than he bargained for as hundreds of dog owners gathered on the beach to pay tribute to Walnut and give him one final walk to remember.
Shortly after the heartwarming event, Walnut was put down. Woods said his beloved pup had been sick for a long time, and he didn't want his companion to suffer any longer.
After the event, attendees took to social media to share photos of Walnut with the hashtag #WalkWithWalnut.
