This phenomenon has baffled scientists for years, and although the reason why is still uncertain, there are several theories that researchers have explored. In addition to being important to the health of our canine companions, scientists hope this research will allow them to gain a better understanding of the human aging process because as dogs age, they experience many of the same conditions we have — such as arthritis , cancer, and diabetes.
Dogs and people age at very different rates. When dogs reach one year old, veterinarians estimate they have matured as much as people have when they reach 15 years old. And after that, the aging process in dogs varies based on their age and size. Although large mammals tend to live the longest, small body size within a species is associated with longer life and slower aging.
Canis familiaris, aka the domestic dog, is a species with a huge size range when it comes to its breeds. In the study, large breeds died more often from cancer than small breeds. One possibility Kraus suggests is that large breeds grow faster, so they may be more likely than small dogs to also experience the abnormal cell growth seen in cancer. Or because they age more quickly, large dogs may succumb to age-related illnesses sooner.
A researcher at the University of Washington, Dr. Silvan Urfer, conducted a large study , collecting data on , dogs who died or were euthanized within a three-year period at U. He found a correlation between the breed of the dogs and their age at death.
For example, among giant breeds, Great Pyrenees lived longer In Dr. Another factor researchers have studied is the size of the breeding population, and its impact on health and longevity. Urfer reported when comparing two dogs with all other factors being equal, that he found annual dental cleanings conducted by a veterinarian reducing risk of death by almost 20 percent.
What they may not know is that, if their beloved pet is too heavy, they are more likely to suffer from other problems such as joint disease, breathing issues, and certain types of cancer, as well as having a poorer quality of life.
These health and wellbeing issues can significantly impact how long they live. One study that focused on 12 specific breeds found the effect on lifespan of extra weight on the smallest dogs, such as Yorkshire Terriers , was even greater overweight: Actively scan device characteristics for identification.

The exceedingly high rate of cancer in Golden Retrievers has led to the largest study of cancer in dogs of its kind. Researchers hope that the study will reveal information about why so many Golden Retrievers suffer from cancer and also about how the factors that contribute to cancer in dogs could also help our understanding of cancer in humans.
Trauma can take many forms, including car accidents and dog fights. Puppies and small dogs have higher incidences of trauma-related deaths than adults or larger breeds, and working dogs also have higher incidences of trauma-related deaths. Keeping your dog on a leash when out of your yard can help prevent some trauma-related injuries, and it is always a good idea to supervise young puppies around other animals and children.
Congenital and inherited abnormalities are not always detectable or predictable. Selecting a responsible breeder and employing responsible breeding practices in your kennel are the best ways to avoid purchasing or producing a dog with a fatal congenital disease. Infectious diseases are no longer the concern they were prior to vaccines, but they still claim canine victims every year.
Approximately 34 percent of adult dogs in the U. This is alarming because research suggests that obese dogs live 2 years less than dogs at a healthy weight.
Obesity puts stress on the musculoskeletal system, leading to osteoarthritis and intervertebral disc disease, and increases their risk of developing diabetes and pancreatitis. Obesity is also associated with cardiac and respiratory conditions such as airway dysfunction and tracheal collapse.
Keeping your dog at a healthy weight reduces the risk of his developing weight-related diseases, improves his quality of life, and gives him a chance to live out his full life expectancy. Predicting the lifespan of your dog is tricky. While it is relatively safe to assume that a small breed dog will outlive a giant breed dog, there are many factors outside of our control that affect the longevity of our pets. This can be frustrating, but luckily there are some things we can do to improve the lifespans of our canine companions.
