Dozens of golden retrievers and their owners paid tribute Sunday to two beloved Boston Marathon dogs -- Spencer and Penny -- ahead of the 127th running of the marathon.
The dogs donned bright yellow bandanas emblazoned with "GOLDEN STRONG," an homage to the bright blue "BOSTON STRONG" flags Spencer and Penny carried at past Boston Marathons, Boston ABC affiliate WCVB reported.

And then on Feb. 26, Powers shared on The Henry Studio's Instagram that Penny also died after doctors found cancerous tumors that had spread throughout her body.
Powers, a photographer and owner of The Henry Studio, told "GMA" in February that he had his golden retrievers start holding the blue flags in 2015 and the duo quickly captured the hearts of runners and spectators along the marathon route. In 2022, Spencer was even named the "official dog of the 126th Boston Marathon."
"He and Penny -- they were just wonderful dogs and each of them were too good not to share, and so that's what we did," Powers said at the time.

Following the Sunday meetup, Powers posted photos on Instagram. In one caption, he wrote, "Quite a touching tribute to an amazing pair. Spencer & Penny forever in our hearts. #bostonstrong."
