The lifespan of small dogs is 12 to 18 years, the lifespan of medium dogs is 10 to 15 years, and the lifespan of large dogs is about 10 years. The larger the dog, the greater the burden on its organs, so its life span will be shorter. Converted to human years, one year old dog is equivalent to an adult, and each subsequent year is equivalent to approximately three human years.

What can affect a dog’s lifespan

1. The dog’s weight

The dog’s weight will affect the dog’s lifespan . Excessive obesity will bring many diseases and health risks to dogs, and can easily lead to premature death of dogs. However, if a dog is too thin, it will also have adverse symptoms such as low immunity, malnutrition and poor physical function, which is also not conducive to the dog's health and longevity. The normal weight of a dog can refer to the standard weight of the dog breed.

2. The size of the dog

The lifespan of a dog is also closely related to the size of the dog. Small dogs will live longer than large dogs. The lifespan of a Great Dane is only 7 In 8 years, the German Shepherd may live to be 10 years old and die, but Teddy can live to be 15 years old. The reason behind this is that large dogs have a faster metabolism than small dogs and will enter the body aging phase earlier.

3. Whether the dog is neutered or not?

Dogs suffering from reproductive diseases can be life-threatening in severe cases and shorten their life span. Generally, male dogs will have testicular cancer, and female dogs will have pyometra. Female dogs are more likely to suffer from reproductive diseases than male dogs, and the older they are, the more likely they are to suffer from pyometra. Spaying and neutering a dog can relatively extend the life of the dog.

4. Bloodline genes

Because breed dogs are the offspring of dogs with relatively close blood relationships, they are more likely to have genetic diseases and fatal diseases caused by bloodline genes. Due to physical defects, the life span may be much shorter than that of non-breed dogs and Chuanchuan dogs.

5. Exercise management

Dogs who exercise regularly will be very strong and have strong disease resistance. Their own aging will be delayed a lot and their lifespan will be longer. However, excessive exercise and strenuous exercise are actually a killer of the dog's health. They will overdraw the dog's life and physical strength, making the dog's aging period come faster!

6. Diet management

Diet can maintain health. Many healthy and long-lived dogs not only maintain regular exercise, but also keep a nutritious and light diet. As for the staple food, choose natural dog food that is light and low-salt, with a reasonable mix of meat and vegetables, so that the elderly dog ​​can eat nutritious, healthy and easy to digest and absorb, thereby extending its life.
