ASHLAND (CBS) — Twelve-year-old Spencer and nine-year-old Penny cheered on Boston Marathon runners in the way they know best: the golden retrievers held flags in their mouths.

Spencer went viral in 2018 after holding a Boston Strong for runners during the rainy Boston Marathon.

“HUNDREDS of runners yelling their names as they went by,” owner Rich Powers wrote on Facebook.

Though Spencer is more of the social media star, Penny was also there. They have been cheering on the runners together since 2015.

Even with this year’s rolling start times, Powers said Spencer and Penny tag-teamed it to provide complete crowd coverage.
