Golden Retriever Lifespan

Work out your Golden's age in human years. Then see what the largest long term study of the breed has found.

How long do Golden Retrievers live?

Golden Retrievers usually live 10 to 12 years, according to the American Kennel Club. That is a bit shorter than the Labrador range of 11 to 13 years. The main reason is cancer, which causes most deaths in the breed. Goldens weigh 55 to 75 pounds, so they age on the large dog chart.

Golden Retriever life expectancy and cancer

In 2012, the Morris Animal Foundation began following 3,044 Golden Retrievers in the United States for their whole lives. It is called the Golden Retriever Lifetime Study. Vets examine each dog every year, and owners fill out surveys. The goal is to learn what raises or lowers the risk of cancer and other disease.

What it has found so far:

Older data points the same way. A 1998 Golden Retriever Club of America survey of 1,444 dogs found that cancer caused 61 percent of 420 deaths. A necropsy study of 652 Goldens at a US vet school hospital found 65 percent died of cancer. Studies of Goldens in the UK and Scandinavia found lower rates, 20 to 39 percent, which suggests that bloodlines or setting may matter.

Who got hemangiosarcoma most?

In the lifetime study, dogs aged 7 to 9 had higher odds than younger or older dogs. Males and heavier dogs also had higher odds. Most cases were inside the body, and survival after diagnosis was very short. Dogs with the skin form survived longer.

Signs to take seriously in a Golden

The AVMA lists warning signs of cancer in pets. These include swelling of the belly, bleeding from the mouth or nose, trouble breathing, lumps, sores that do not heal, weight loss and lameness. If your Golden suddenly collapses or seems very weak, call your vet right away.

The DNA clock column comes from the UCSD study of Labrador blood. Goldens are close in size and type, so the clock is a reasonable second opinion for this breed.

Golden Retriever senior age

Treat a Golden as a senior from about 8. The AVMA rule of the last 25 percent of life gives 7.5 to 9 years with the AKC range. Senior pets need a vet visit at least twice a year, and a Golden's checks should include a hands on lump check and talk about belly and heart signs.

What is hemangiosarcoma?

A fast spreading cancer of blood vessel cells. It often starts in the spleen or heart. It was the most common cancer in the lifetime study, found in 16.1 percent of the 3,044 dogs by the end of 2024.

When is a Golden Retriever a senior?

At about 7.5 to 9 years, using the AKC range and the AVMA rule of the last 25 percent of life. The AVMA guide for large dogs gives 8 to 9.

About 55 on the large dog chart, and about 64 by the DNA clock.
