Losing a dog is a terrible experience for every dog owner. We don’t want our furry friends to leave us, but that is the cycle of life and death. However, some dog breeds tend to resist that cycle better than others. Many factors determine the average lifespan of your dog and some dog breeds are clearly ahead of the others. But, what is the healthiest dog breed in the world? What dog breed lives the longest?

Factors That Determine Dog’s Lifespan

Genetics plays the biggest role in the average lifespan of the dog. However, this is not the only factor that determines how long your dog will live. Other important factors we need to take into consideration are the dog’s size, diet, activity, and environment.

There is a clear correlation between the size and the average lifespan of the breed. Researchers have determined that the smaller dog breeds tend to live longer than the larger ones. Therefore, if you are looking for a dog that will stay with you for a long time, choose the smaller breed.

Good genetics doesn’t mean much if your dog doesn’t get all the nutrients, minerals, vitamins his body needs to function properly. An unbalanced diet can cause many serious health issues to occur. Therefore, it is crucial that your dog gets a high-quality, well-balanced diet rich in all the necessary nutrients.

To stay healthy, dogs, just like humans, need regular physical activity. A dog that is not physically active is at risk of becoming obese. Overweight dogs are also prone to heart issues. Therefore, make sure to take your dog daily for a walk and play some games with him while you are out.
