If you have a dog, you most likely heard about the rule: 1 According to human standards, the dog’s year of life is 7 years. It turns out that math is not so simple. Dogs mature faster than we are in the early stages. Therefore the first year of your canine’s life buddy is approximately fifteen human years.
The size and breed of the dog also play a role. Small breeds tend to live longer than large breeds, but they less mature faster in the first few years of life. Large puppies may age more slowly at first, but they move closer faster to his average age of 5 years. Small and decorative breeds not considered old until 10 years old. Medium sized dogs are somewhere between these indicators.

How to find out the age of the dog?
If you took a puppy or dog, but don’t know its history, then you you can’t know exactly how old she is. However, even if you don’t know your pet’s birth date, you can still rate how old is she.
Her teeth will give you a rough idea of her age. All of these age comments may vary for each individual. dogs, and they also depend on oral hygiene, which received a dog throughout life.
- Up to 8 weeks (2 months): all baby teeth in place
- Up to 7 months: all molars must be white and clean
- By 1-2 years: teeth become darker, posterior teeth may turn yellow
- 3-5 years: tartar is formed on some teeth, some teeth wear out
- 5-10 years: teeth have visible signs of wear and tear
- 10-15 years: teeth wear out, large deposits are possible tartar, some teeth may be missing
Your veterinarian can more accurately estimate your dog’s age using full medical examination and analyzes of internal organs. Old dogs begin to show certain signs of aging:
- Turbidity of the eyes
- sagging and inelastic skin
- weakening legs
- Gray hair. The hair begins to turn gray around the muzzle, and then spreads to other areas of the head and body.
Why do small dogs live longer than large ones?
This phenomenon is still puzzling scientists, and they still have to explain the relationship between body weight and life expectancy dogs. Generally speaking, large mammals such as elephants and whales tend to live longer than small ones like mice. So why do small dogs live longer than large ones?
Some researchers believe that the life of large dogs with accelerates over time. Scientists have concluded that every 2 kg body weight reduces the dog’s potential lifespan for about 1 month.
One likely reason for this is that larger dogs can become more vulnerable to age-related diseases and that the accelerated growth of large dogs can lead to higher the likelihood of abnormal cell growth and cancer death. Researchers are planning additional future large-scale experiments to better explain the relationship between size and mortality.
