Famous Boston Marathon Dog, Spencer, Dies At 13 After Battling Cancer

Spencer — the dog who ended up being a star for cheering on runners throughout the Boston Marathon each year — has actually regretfully died after battling cancer. He was 13.

Spencer’s owner, Rich Power, made the statement on Tuesday … stating the golden retriever passed away at their house last Friday under the care of their vet.

“We are ravaged to share the news of Spencer’s death,’ Powers stated on social networks.

“Spencer has overcome some severe medical challenges over the past several years. We thought we would be lucky to have him for an extra month.”

Powers — who was talented the puppy in 2009 — described he was detected in September 2022, and regrettably, the cancer was unusable.

“Spencer was not ready to give up and with the love and positive energy sent to him by hundreds of thousands of fans, He beat the odds and gave us 28 months.”

In reality, the Boston Athletic Association called Spencer the main dog of the marathon in 2015 and honored him with a picture and medal at an event in Boston.

“Spencer, your spirit and determination inspired us all,” the B.A.A. stated after his death.

“We’ll miss you, and are proud to call you a friend and forever the Official Dog of the Boston Marathon.”

Spencer’s owners are asking fans to contribute to his memorial fundraiser … which assists the Morris Animal Foundation Golden Retriever Lifetime Study.

The research study concentrates on canine health research studies in the U.S. to “identify the nutritional, environmental, lifestyle and genetic risk factors for cancer and other diseases in dogs.”
