【Watch Batman Death in the Family Online】

Mark Woods said goodbye to his beloved dog Walnut on Watch Batman Death in the Family OnlineSaturday, but not before he -- and a horde of well-wishers -- accompanied the pup on his final beachside walk.

"Sadly I am having to have Walnut euthanised on Saturday 12th November and so we will be having a last walk together on his beloved Porth Beach at 9.30am," Woods, who lives in Cornwall, England, wrote in a Facebook post. "I would love it if dog lovers/owners and friends would join us for a celebration of Walnut on his favourite Porth Beach."

"He has had an incredible life and having reached the grand age of 18 is ready for his final sleep," Woods added.

Inspired by Woods' words and Walnut's story, hundreds of people -- and dogs, of course -- turned up for the stroll on Walnut's favorite beach, which is closed to dogs in the summer months.
