After two years, the Boston Marathon was finally back to normal.

This therapy dog is a fan favorite and racers line up to get their picture taken with him.

Spencer first gained notoriety in 2018, when his owner Richard Powers put him in a yellow raincoat.

Unfortunately, Powers recently found out that Spencer had another cancerous tumor and needed to start chemotherapy.

That made his presence at this year’s marathon even more special.

The impact he’s having is exemplified by an incredible gift that one runner left Spencer this year.

Spencer the golden retriever has been supporting racers at the Boston Marathon since 2015.

In 2022, he was named the official dog of the 126th Boston Marathon.

Spencer’s owner wasn’t sure he’d be on the course this year.

After beating cancer in 2020, a tumor is now back and Spencer is undergoing treatment.

But he made it and was proud to give his support to all the runners.
