How long do dogs live? When it comes to figuring out how old your furry friend is, the old method of calculating “dog years” just doesn’t cut it anymore. Recent studies have shown that a dog’s lifespan can vary a lot depending on its breed, size, and other factors that we’re still trying to understand.

Average Dog Lifespan

Well, it depends. On average, dogs live between 10 to 13 years in dog years, but it can vary based on the type of dog. Dogs come in all shapes and sizes because of humans. So, a little Chihuahua might live longer than a big Great Dane. But, if you’re wondering about how long do dogs live in human years, that’s a bit different.

Usually, smaller dogs live longer than bigger ones. Scientists aren’t sure why this happens. Normally, smaller animals live shorter lives than bigger ones. But one reason could be that bigger dogs might find it harder to deal with health problems as they get older.

Things like not being able to control when they go to the bathroom or having trouble moving around might be harder for big dogs. Sometimes, these issues can lead to putting a dog to sleep. Different-sized dogs also tend to get different kinds of sicknesses.

Well, it’s not just about how they’re treated, but also about their genes. If a dog comes from a purebred family, it might have some health problems because its parents were quite similar. But if it’s a mix of different types of dogs, it might be healthier and live longer.

Some dogs are bred for specific jobs or looks, but this can sometimes lead to them having health issues. For instance, dogs with squished faces like English Bulldogs can have a hard time breathing and might get too hot easily, which can make them sick.

What is the lifespan of small dogs?

Well, it depends on their size. Smaller dogs usually live the longest, around 10 to 15 years. But as they get older, they might have some health problems.

Different breeds of medium-sized dogs can have different lifespans and health concerns. Bulldogs, with their short noses, often have health problems, while Australian Shepherds, known for their hard work, tend to have fewer genetic issues and can live to be 15 years or even older.

  • French Bulldog: 10-12 years
  • Cocker Spaniel: 12-15 years

  • Boxer: 10-12 years

Even when they’re just 6 years old, big dogs like Great Danes are already considered seniors because their joints wear out faster due to their size. Also, these huge dogs are much more likely to get bone cancers and diseases that affect their nerves compared to smaller dogs.

  • Great Dane: 7-10 years
  • Irish Wolfhound: 6-8 years
  • Newfoundland: 8-10 years
  • Saint Bernard: 8-10 years

Ways to increase your dog’s lifespan.

Conduct thorough research.

If you’re wondering about it’s important to know that the lifespan of a dog can vary a lot depending on its breed. So, if you have a specific breed in mind, it’s really crucial to do some research. Find a breeder who cares a lot about the health of their dogs.

Good breeders will check for common diseases in their dogs before breeding them. They might even do some genetic testing to make sure the puppies are healthy. Knowing about the lifespan and health problems of your puppy’s family can help you choose the right dog for you.

When it comes to mixed-breed dogs, they might have a longer lifespan than some purebred ones. Designer breeds like Goldendoodles and Labradoodles were initially bred for better health but can now have their own issues due to overbreeding. It’s important for breeders of these dogs to meet the same standards.

Dogs from shelters, often mixed breeds, may have fewer health problems compared to designer breeds. However, they can still develop breed-specific illnesses. Pet owners can consider DNA testing their shelter dogs to anticipate potential health issues. Understanding your dog’s background can help you prepare for any health challenges they may face.

Follow Your veterinarian’s advice.

When it comes to “How Long Do Big Dogs Live,” it’s crucial to listen to your vet’s advice about keeping your dog healthy. This includes getting vaccinations and using preventatives for fleas, ticks, and heartworms to protect against diseases.

Regular check-ups are important too. Your vet might recommend tests to check for parasites in your dog’s intestines and blood each year. They may also suggest routine blood tests to check the health of your dog’s liver, kidneys, and bone marrow. Doing these tests when your dog is young and continuing them as they get older can help catch diseases early when they’re easier to treat. As dogs age, they might need more tests to check for age-related issues.

For certain breeds like Golden Retrievers, your vet might suggest regular imaging tests like X-rays and ultrasounds as they get older. This helps keep an eye out for specific types of cancer that they might be prone to.

Ensure your dog maintains a healthy weight.

Maintaining a healthy weight is super important for your dog’s longevity. For example, a study on Labrador Retrievers showed that dogs who stayed at a good weight lived about two years longer than those who were overweight.

To keep your dog at a healthy weight, make sure to feed them the right amount of food at each meal. It’s also important to keep track of the treats and snacks they get, so you can adjust their food intake as needed. If you’re not sure whether your dog is at a healthy weight, your vet can help you figure it out.
