Owning a dog can make your life amazing and frustrating. Puppies can be difficult to train, but it's hard not to love them. So how long do dogs live and what are the benefits they provide to their owners? In this article, we'll discuss the lifespan of a dog and five scientific benefits of caring for one.

The lifespan of a dog depends on certain factors like size, age, and breed:


Throughout the years, there has been popular research and the discovery that larger dogs have a shorter lifespan compared to shorter dogs. A dog with more body mass and size can develop more physical ailments related to exercise compared to a dog with a smaller body mass that is comparatively small in size. For example, a Wolfhound will have an average lifespan of 6–7 years and Fox Terrier can live up to 15–16 years! That is a huge difference.


This factor is the main part. There is this myth that one human year is equal to 7 whooping dog years. That is not scientifically accepted or proven, but it is accepted by many. However, a tough calculation shows a human aged by one year will be equal to a 10 to 15-year-old dog. That is, the dog will be fully matured and have all sexual capabilities, etc.


The lifespan of a mixed dog will be completely different from distinct breeds of dogs as there are two types of breeding: inbreeding and crossbreeding. Dogs that are inbred have shorter lifespans compared to those that are crossbred. Inbred dogs are at risk of sharing genes that can carry inheritable illnesses and conditions. Dogs that are crossbred tend to have healthier and longer lifespans.

5 Scientific Benefits of Having a Dog

Apart from the emotional benefits that bringing a puppy has to offer, there are many scientific benefits of having a dog as well. You don’t just have to own them to reap all the health benefits that they have to offer, you can hang out with them, and they will bring you so many advantages. Here are the top 5 most influential ones among them.

1. Heart Health

Dogs don’t just feel good to your heart; they are linked to the actual health of the heart as well. If you have a dog, you will have fewer chances of having blood pressure issues, according to research. Research also states that owning a dog has direct impacts on cholesterol levels and triglyceride levels; they tend to get lowered.

This means that your cardiovascular health is going to be positively impacted by the presence of a dog. You will become less likely to have heart attacks, as well. The best part is that studies show that the survival rates of those who have a heart attack is much higher in dog owners than those who don’t own a dog.

2. Resistance Towards Allergies

Pets are known to mostly trigger allergies in people. However, kids that have been living with a pet since childhood become more resistant to allergy issues. They are less likely to have allergy issues when they grow up.

According to a study in the journal Microbiome, pregnant women encountered a bacterial exchange, and their children would turn out to have two bacteria called Oscillospira and Ruminococcus, which lower the risk of allergies. This means they are able to resist allergies better even if the pet is not thereafter, they are born.

3. More Exercise

This is more of a tendency than a health benefit, which has a positive impact on health. A dog owner has to walk his dog several times a day, especially in bad weather. An average adult is supposed to have at least 30 minutes of walk every day, and according to research, dog owners are more likely to reach that goal.

Taking the dog out for walks every day sets a steady schedule of being able to walk every day; you cant it out of weak willpower as well. You will also need to play with them every day, and this exercise is going to have numerous health benefits.

4. They Can Detect Low Sugar Levels

According to a British Medical Journal, more than a third of dogs that live with people suffering from diabetes are able to detect low blood sugar levels, even before the patients are able to. This causes them to exhibit behavioral changes. Most of the time, dogs manage to nudge the patients into eating what is right for them.

5. They Can Help During Seizures

Dogs are capable of detecting an oncoming seizure. They can warn the owners so that they can get help or call emergency services beforehand.
