Spencer, beloved Boston Marathon dog, dies after battle with cancer

Spencer, a golden retriever who became famous for cheering on runners each year during the Boston Marathon, has died.

Spencer's owners confirmed Tuesday that the "Official Dog of the Boston Marathon" died.

"We told him we loved him, and we thanked him until his last breath," Spencer's owner, Rich Powers said. "He was a gift given to us that we shared with the world, and we just gave it back."

Spencer was 13 years old and in October was diagnosed with untreatable liver cancer. It was the second time Spencer battled cancer, previously having a tumor removed in 2020.

"Throughout all of his treatments, I cannot stress this enough, this dog handled it like champ," Powers said. "He gave us his last gift to not make us wonder for the rest of our lives, 'Did we make the right decision?' We know we made the right decision."

In January, artists unveiled a massive portrait of Spencer at the Fairmont Copley Plaza as he was named the honorary canine ambassador for the hotel.
