One year for a dog is equivalent to 18 years for a human. At this time, the dog becomes an adult. Each additional year after that is equivalent to adding 4 years to human age, so the average lifespan of a dog is about 13 to 15 years.

Tips that can extend the life of a dog include moderate exercise. Daily walks for older dogs can satisfy their exercise needs. Pet dogs should be fed scientifically, their daily diet should be regular, and they should choose healthy food to feed. You should take your dog to the pet hospital for physical examinations regularly, do deworming every month, and get vaccinated on time every year.
