When we have dogs at home, we all hope that they will stay with us for a longer time. However, the life span of each dog is different, so how long is the average life span of a dog? What does the length of a dog’s lifespan depend on? If you have a dog at home or want to raise a dog, come and have a look.

The lifespan of small dogs is about 12-16 years, and the lifespan of large dogs is about 8-12 years. A giant dog like the Great Dane can live to be 8 or 9 years old, which is considered longevity. The metabolism of small dogs is relatively small, and the metabolism of large dogs is relatively large, so the life span of large dogs is shorter than that of small dogs.

There are many factors that determine the life span of a dog. The difference between purebreds and mixed breeds can affect the lifespan of dogs: If the dog is an inbred purebred dog, it may carry many genetic diseases. When breeding mixed-breed dogs, although there is no guarantee that there will be no genetic diseases, they can avoid some ancestral genetic diseases and become healthier.

Neutered dogs live longer: Neutering can effectively prevent many reproductive diseases. Female dogs are prone to pyometra, while male dogs are prone to testicular cancer. If you don’t want your dog to have children, it’s best to neuter it at the appropriate age.

In addition, the owner's care can determine the dog's lifespan: the dog's daily life, diet, exercise, care, etc., will all affect their lifespan. Paying attention to your dog's diet, exercise, etc. every day can make their lifeline longer and stay with you longer.

In fact, the life span of dogs is not very long. If you have a dog, you should spend more time with them. They are also very lonely~
