Small health problems can snowball if owners aren’t regularly taking their dogs for checkups, experts warn. The number one cause of death for dogs is cancer, with six million diagnosed annually in the US, according to the National Cancer Institute. Pups with poor diet and little exercise are at heightened risk, so ensuring they stay active and eat well is incredibly important and can help them live as long as possible—potentially extending their life by up to 30 percent, researchers told The Independent.
Doggy Dangers
Cancer is the leading cause of death in dogs across breeds, with more than four million dying of the disease each year. Heart disease is the second leading cause, according to Matthew Kaeberlein, founder and co-director of the Dog Aging Project. Trauma and accidents are third. Obesity is often a contributing factor in cancer, age-related diseases, and heart disease. Dr. RuthAnn Lobos, senior veterinarian at Purina, calls it the "biggest threat" to lifespan. Purina’s 14-year study found Labrador Retrievers fed lean meals lived nearly two years longer.
Beyond Genetics
Most healthy dogs live 10-15 years, but genetics play a strong role, says Daniel Promislow, co-director of the Dog Aging Project. Small health problems can snowball if owners skip regular checkups, especially after age 7. Oral health is often overlooked: poor dental health is linked to metabolic disease, cardiovascular issues, and cognitive decline. At-home cleanings can miss major problems.
Paw Patrol
To protect your dog, take preventative action: feed nutritious meals, avoid overfeeding, limit processed human foods, and prioritize exercise. Regular vet visits, vaccines, and pest prevention are key. Genetic testing can identify specific conditions. Minimize exposure to pollutants, especially for breeds prone to cancer like Pugs, Shar Peis, and Rottweilers.
Senior Support
Older dogs need extra care for arthritis, cognitive decline, and mobility issues. Low-impact activities like frisbee, surfing, or walks help maintain movement without straining joints. Mental health is also crucial: stressors like arguments at home can impact a dog’s health and survival, says Noah Snyder-Mackler of Arizona State University.
A Better Future
Studies on dogs can reveal environmental risk factors that also affect humans. With proper resources, extending a dog’s healthy lifespan by 20-30 percent is achievable, and potentially more, says Kaeberlein.
