How Long do Dogs Live?

Dogs have been our loyal companions for many centuries and they have been welcomed into our homes as family members. They range in size from tiny lap dogs to massive working dogs, and they come in every shape, color, and personality type imaginable. But one of the things that all dog owners have in common is the question of how long our furry friends will be with us. The answer to that question isn’t always simple, since there are a number of factors that can affect a dog’s lifespan.

The average lifespan of a dog is about 10-12 years, although this number can vary greatly based on the breed of dog. Some breeds, such as the toy poodle, have an average lifespan of 15 years or more, while others, such as the bulldog, have an average lifespan of only 8 years.

Dogs come in all shapes and sizes, from the tiniest Chihuahuas to the gigantic Great Danes. But how long do our canine friends stick around? The answer may surprise you.  Depending on the size, weight, and breed of the dog, its lifespan can vary greatly. Read on to learn more about the lifespan of dogs.

The Life Expectancy of Dogs

The life expectancy of a dog depends on a number of factors, including size, diet, and whether the dog is an indoor or outdoor pet. Small breeds generally live longer than large breeds, and purebred dogs usually have a longer lifespan than mixed breeds. A healthy diet and regular exercise are important for all dogs, regardless of breed, to help them live long and active life.

The Numbers

The average lifespan of a dog is around 10-12 years, although this number varies greatly based on the breed.  Smaller breeds, on average, tend to live longer than larger breeds.  Some breeds have an average lifespan of only six to eight years, while others may live 15 years or more.

The Factors that Affect a Dog’s Lifespan

Dogs’ lifespans are greatly affected by their breeds. Smaller dogs tend to live longer than larger dogs, and purebred dogs live, on average, three to five years longer than mixed-breed dogs. However, there are many other factors that contribute to the length of a dog’s life.  Good nutrition, less exposure to environmental toxins, and regular exercise all play a role in how long a dog will live. Important factors at a glance include:

  1. Diet: A dog’s diet plays a big role in its lifespan. A healthy diet full of nutrients will help keep a dog’s body strong and its immune system functioning properly.
  2. Exercise: Exercise is important for all animals, but it is especially important for dogs. It helps keep them trim and fit, and it also helps keep their minds sharp.
  3. Genetics: A dog’s genetics play a big role in how long it will live. Some breeds are known to have longer lifespans than others.
  4. Environment: The environment a dog lives in can also affect its lifespan. Dogs that live in clean, safe environments are more likely to live longer than those that do not.

The Breeds of Dogs with the Longest Lifespans

Research shows that the average life expectancy for a dog is anywhere from 10 to 13 years, depending on the size, breed, and mix of breeds. Smaller dogs, on average, live longer than larger dogs. Certain smaller mixed breeds, like the Maltese Shih Tzu, have a reputation for being long-lived. Other examples of dog breeds that have extraordinary lifespans are as follows:

  • Chihuahua – approx. 17 years
  • Toy Poodle – approx. 15 years
  • Shih Tzu – approx. 15 years
  • Maltese – approx. 15 years
