Why Do Small Dogs Live Longer Than Bigger Dogs?

In nature, some of the largest animals on the planet also have some of the longest lives, include elephants and whales. But the reverse seems to be true when it comes to dogs. In fact, the larger the dog, the shorter their lifespan.

Researchers have done numerous studies to determine why larger dogs tend to have shorter lives. Although there are no clear answers as to why this is, there are several popular hypotheses.

1. Bigger dogs experience accelerated growth and as a result, also age faster.
2. The accelerated growth rate in larger dogs increases the risk of the growth of abnormal cells that cause cancer and other diseases.

Research into this topic is ongoing with many dog owners hoping to find answers that could result in the lengthening of their companion’s lives.

The Dog Aging Project

Dog owners who are interested in contributing to ongoing research might want to consider projects like the Dog Aging Project!

This project will be ongoing for at least a decade and will review data shared by participating dog owners. The goal is to determine biological and environmental factors that can impact how long a dog lives and to learn more about how they age.

Joining the project is free and dogs of all breeds and ages are welcome!

Steps To Make Sure Your Dog Has A Long And Healthy Life

There are certain steps that every dog owners can take to ensure that their pet has a happy life and one that is as long as possible.

Visit The Veterinarian Regularly

Yearly check-ups are important for several reasons:

1. Preventative Care: Flea and tick preventative, heartworm preventative, and vaccines are all important because they can prevent the transmission of diseases that can put your dog’s life at risk.

2. Early Diagnosis: Dogs can be very stoic creatures who don’t show signs that they are ill until their disease has progressed. A veterinarian may notice the subtle signs that your dog is ill or yearly health screens could have results that could catch a disease before it has the chance to do significant damage.

Provide Your Dog With A Healthy Diet

Just like humans, it’s important for dogs to eat a healthy diet in moderation. Obesity can cause other serious medical conditions like diabetes and heart disease. Be sure to be strict about the amount of food you give your dog and limit high calorie treats.


Regular exercise is a great way to keep your dog healthy! Walking, running, swimming, chasing a ball, and playing frisbee are just a few examples of how you can keep your dog active. You may even want to consider joining in on individual or team sports with your pup!

The best part is that when a dog is regularly exercised, this also frequently results in better behavior!

Spay And Neuter Your Dog

In addition to reducing the population of homeless pets, spaying and neutering your dog can help to save a life. These routine procedures eliminate the possibility of a dog suffering from a pyometra or certain types of cancers later in life.

Give Them Lots Of Love!

Petting and loving your dog can help to reduce stress levels for both you and your canine companion. Less stress = a longer life!
