Dogs live forever, right? Right!? Unfortunately, like humans, dogs are mortals. Anyone who has lost a pet knows how heartbreaking it is to say goodbye. They are truly family members. If youre someone who hates goodbyes or simply wants a companion for as long as possible, look into the longest-living dog breeds. On average, domesticated dogs live about ten years, but the dogs on our list have been known to live well into their teens. Youll notice most of these pups are on the smaller side. While breed alone isnt going to tell you how long your dog will live, it can give you a pretty good idea.
You may have heard that if a dog is one year old, shes actually seven in human years. Wrong! While canines definitely age faster than humans, this simple calculation is misleading. According to the American Veterinary Medical Association, dogs actually hit infancy, childhood and adolescence all in their first year. Thats a lot of rapid growth (and part of the reason large breeds like Great Danes could get injured if over-exercised as puppies, because their joints arent fully equipped to handle all of their body weight). Most breeds reach adulthood between one and three years old. Dogs ages six through ten are considered senior citizens. When a dog turns seven, theyve effectively entered the geriatric phase of their life.
Theres some conflicting data on whether or not a breed directly impacts a dogs lifespan. Other factors seem to matter more when it comes to longevity. One 2018 study out of Budapest, Hungary, found that purebred dogs (dogs whose parents and ancestors are all the same breed) did not live as long as mixed breeds. Purebred pups in this study also developed health issues earlier than their mixed breed counterparts. Even the purebred dogs in the studys oldest dog group were younger than the mixed breeds in the oldest dog group.
On the other hand, a 2019 U.S. study did not find significant evidence that mixed breed dogs outlive purebred dogs. The researchers noted dogs with a more varied genetic background (aka, a mix of various breeds) lived roughly three to six months longer than dogs bred from one specific line; however, the same study found that dog size is a better indicator of lifespan than breed. Canines from the Mountain ancestral group (like Bernese Mountain Dogs and Great Pyrenees Mountain Dogs) were found to live 3.5 to 4.6 years less than other purebred groupslikely an unlucky combination of size and purebred status.
As mentioned, most of the longest-living dog breeds are small-sized pups. Scientists have determined this is basically because large dogs age more quickly than small dogs. Large breed bodies wear out sooner. Some researchers surmise cancer appears in large breeds more often (and sooner) because of their rapid growth spurts early in life.
Theres no secret to tiny canine DNA that makes them live longer. However, there are many things dog owners can do to extend the lives of their beloved pupsno matter their breed or height.
Without fail, the one thing researchers agree on when it comes to doggy longevity is the importance of maintaining a healthy weight. Dogs who are overweight have a much higher chance of developing health issues like respiratory problems, heart disease and kidney failure. Keeping your dog at a healthy weight through diet and exercise is the single best thing you can do to ensure a long, happy life.
Beyond that, regular dental checkups can drastically improve your dogs overall health. Avoid smoking around your dog or inside your home; secondhand smoke is linked to early signs of aging in canines.
Play with your dog regularlyespecially if you have an intelligent or working breed who needs mental stimulation. Happy dogs tend to live longer! In fact, the Hungarian study mentioned above says understanding past traumas your dog has experienced and preventing similar situations from happening in the future can improve overall health.
Finally, dont ignore strange changes in a senior dogs behavior or appearance. Almost half of dogs over the age of ten who pass away die from cancer. Cancer can manifest in visible tumors or atypical behavior like lethargy or loss of appetite.
