Dog lifespan

The average lifespan of large dogs is 10-13 years, that of medium-sized dogs is 12-15 years, and that of small dogs is as long as 15-20 years. Large dogs generally age faster than small dogs. With the improvement of the current breeding environment and medical conditions, and the use of scientific feeding methods, the life span of dogs is slowly increasing, so owners must pay attention to the scientific nature of feeding.

Reasons why large dogs age faster than small dogs

1. Large dogs need more nutrients and energy to support body development, so their cell renewal is consumed faster.
2. Large dogs are more likely to get cancer than small dogs because they grow faster and are more prone to abnormal cell growth.
3. Large dogs are more likely to suffer from joint diseases. Their large size can easily lead to patellar luxation, arthritis and other diseases.

Factors affecting dog lifespan

1. Obesity. Obesity will put a huge burden on the body and easily cause dogs to suffer from cardiovascular diseases.
2. Sleep quality. Domestic dogs generally live longer than free-range dogs because domestic dogs do not have to remain in a very nervous state to the outside world and can sleep better.
3. Nutritional balance. Dogs require a dynamic nutritional balance in order for their bodies to function healthily. Especially dogs after the age of 7 need an annual physical examination and adjust their diet according to their health level and nutritional needs.
4. Exercise. Dogs need a moderate amount of exercise to improve their physical fitness and maintain their physical functions.
5. Socialize. Dogs who socialize more can relieve their inner depression, make them less anxious and happy.
