Dogs are called puppies from birth to 1 year old; they are adult dogs from 1 to 7 and a half years old; after 7 to 8 years old, they will begin to enter their old age. Regarding the issue of dog lifespan, some people abroad have made statistics and found that: hybrid dogs live longer than purebred dogs, small dogs live longer than large dogs, male dogs live longer than female dogs, and dogs raised indoors live longer than dogs raised outdoors.

From a medical point of view, a dog is called a puppy from birth to 1 year old; an adult dog is 1 to 7 and a half years old; after 7 to 8 years old, it will begin to show obvious symptoms of aging. For example, sleeping time increases, activity time decreases, peeing frequency increases, and reactions appear slow, etc. If you convert a dog to human age, for a dog, its first year is equal to 6 human years. Thereafter, the age increases by 6 years each year. So if the dog is 8 years old, converted into human age, it is equivalent to 50 to 60 years old. Because of the different varieties, the differences in aging are also very obvious.

Large dogs age faster than small dogs. Their golden years are between 2 and 8 years old. After the age of 8, their ability to perform work is greatly reduced. Generally speaking, the average life span of a dog is 8 to 12 years. Miniature and small dogs, such as Pomeranians, Maltese and Poodles, usually have a life span of 9 to 13 years; medium-sized dogs, such as Miguel, Shiba Inu and American Cocker Spaniel, have a life span of 9 to 11.5 years; large dogs Dogs like Husky, Labrador and Dalmatian have a slightly shorter lifespan, with a lifespan of 7.5 to 10.5 years.

However, due to improvements in medical care and the quality of care dogs receive, the lifespan of dogs is increasing. Some people abroad have made statistics and found that the life span of dogs is related to various conditions such as breed, feeding and management. For example, mixed breed dogs live longer than purebred dogs, small dogs live longer than large dogs, male dogs live longer than female dogs, dogs raised indoors live longer than dogs raised outdoors, and even black dogs live longer than other colorful dogs. Among them, dogs raised indoors live longer. has the highest proportion. It can be seen that the quality of feeding and management is an important factor affecting the life span of dogs.
