Dogs bring unconditional love and comic relief to our lives, two endearing traits that lead us to regard them as close friends or members of the family. It’s natural to want to keep our furry loved ones around as long as possible, and that leads to the question of just how long can we expect our dogs to live.
Although several factors determine a dog’s lifespan, size is one of the most obvious. Just 13 percent of the largest dog breeds live more than 10 years, according to the WebMD Pet Health Center. In contrast, almost 40 percent of small dogs live 10 years or longer. Some small dogs can live as long as 14 years. It is believed that smaller dogs live longer because their internal organs do not have to work as hard to function.
Genetics, gender and spaying or neutering also have a role in your dog's longevity. Spaying and neutering, for example, can nix the chance that your dog could get cancer or other problems associated with the reproductive organs.
Specific breeds of dogs are prone to certain types of diseases, especially as they age. In-breeding in purebred dogs can cause health problems as well, something that isn't a factor for mixed breeds or dogs that also are affectionately called mutts.
Statistically, female dogs usually live up to two years longer than their male counterparts. In essence, stats for longevity favor dogs that are female, mixed-breed and small.
Sparkling teeth not only make your dog look good, they add to his comfort and overall health. Good dental health is important because it helps prevent ailments that can shorten a dog's life. Bacteria from poor dental health can travel through the bloodstream, and cause heart, liver and kidney problems.
However, take heart, because problems caused by poor oral hygiene are avoided easily by daily brushing and routine dental cleanings at the vet. Just remember: It's best to start daily brushing when your dog is still a pup, so he gets used to the idea.
A healthy lifestyle can extend how long people live and the same is true for dogs. A dog that is well-trained, eats premium food, gets plenty of exercise, receives mental stimulation and stays up-to-date with vet check-ups has a better chance of living a long and healthy life.
Dog trainer Cesar Milan, also known as the Dog Whisperer, says it's important to set aside daily playtime with your dog that allows him to express his specific talents. For example, Milan suggests playing "search and rescue" by allowing your dog to hunt down a toy or other object that you hide. Also, maybe maybe your dog prefers leaping high into the air to catch a tennis ball.
The American Kennel Club offers guidelines on how much exercise is appropriate for specific breeds. When in doubt, let your dog be your guide for how much exercise and attention he needs. Just be sure to set boundaries and don't let him overdo it.
