Golden retrievers gather to honor Boston Marathon dog Spencer, who lost his battle with cancer

For years at the Boston Marathon, runners were able to look along the sidelines for a beacon of hope: A golden retriever named Spencer waving a "Boston Strong" flag. Spencer had been a staple at the race since 2015, but sadly, he died earlier this year. At the 2023 marathon, his legacy lived on, thanks to fellow goldens and their owners. 

A group of golden retrievers walked to the iconic finish line on Boylston Street near Copley Square on Sunday to honor Spencer. 

MA Golden Meetups, a group that organizes such events for golden retrievers, planned the walk. When Spencer died in February, MA Golden Meetups was holding an event, the group's co-founder Elisha Bussiere told CBS Boston.
