How old would my dog ​​be if he was a human?

Like many owners, you've probably wondered how old your dog would be if he were a man. We often hear that it suffices to multiply dog ​​years by 7 to convert them into human years. However, this calculation is totally wrong because the aging of each dog also depends on its size, breed, and lifestyle.

In addition, the multiplier ratio is not proportional throughout the life of the animal, the dog tends to "age" more quickly during its first two years, then aging stabilizes and accelerates again in the last years of his life. It is therefore better to refer to the values ​​calculated by veterinarians... Quickly discover the human age of your doggie on our tables!

Correspondence human age of small dogs (< 15 kg)

Here are the dog-human age equivalences calculated for small dogs (up to 15 kg) such as Poodles, Yorkshires, Dachshunds, Cockers, Cavaliers King Charles, etc. From 2 to 18 years old, we can observe in a simplified way that a dog year is equivalent to 4 human years. The threshold of senescence, the turning point in the dog's life, is indicated in bold: if yours has crossed it, a check-up visit to the veterinarian is strongly recommended for a health check-up.

• 1-year-old dog = 20 years in equivalent human age
• 2-year-old dog = 28 years old
• 3-year-old dog = 32 years old
• 4-year-old dog = 36 years old
• 5 year old dog = 40 years old
• 6 year old dog = 44 years old
• 7 year old dog = 48 years old
• 8 year old dog = 52 years old
• 9 year old dog = 56 years old
• 10 year old dog = 60 years old
• 11 year old dog = 64 years old
• 12 year old dog = 68 years old
• 13 year old dog = 72 years old
• 14 year old dog = 76 years old
• 15 year old dog = 80 years old
• 16 year old dog = 84 years old
• 17 year old dog = 88 years old
• 18 year old dog = 94 years old
• 19-year-old dog = 100 years old
• 20-year-old dog = 110 years old

Correspondence human age of medium dogs (15 to 40 kg)

Medium to large-sized dogs, such as the German Shepherd, Labrador, Retriever, Beauceron, Boxer ...age faster than small dogs. We observe that a dog year is then equivalent to 6 human years, and a slight slowing down of aging takes place between 10 and 13 years. Because of this accelerated process compared to a small dog, the average longevity of a dog in this category is reduced: 16 years against 20 years in smaller breeds.

• 1 year old dog = 18 years in equivalent human age
• 2 year old dog = 27 years old
• 3 year old dog = 33 years old
• 4 year old dog = 39 years old
• 5 year old dog = 45 years old
• 6 year old dog = 51 years old
• 7 year old dog = 57 years old
• 8 year old dog = 63 years old
• 9 year old dog = 69 years old
• 10 year old dog = 75 years old
• 11 year old dog = 80 years old
• 12-year-old dog = 85 years old
• 13-year-old dog = 90 years old
• 14-year-old dog = 96 years old
• 15-year-old dog = 102 years old
• 16-year-old dog = 110 years old

Correspondence human age of large dogs (> 40 kg)

This last category includes large to very large dogs: Mastiffs, Bouviers, Leonberg, Newfoundland, Saint Bernard, etc. The latter live shorter than average dogs, the maximum longevity being 13 years and the threshold of senescence estimated at around 6 years. Thus, the dog would take each year 9 years more if it were a human. In addition, aging accelerates even more from the age of 10, when your dog would almost be a hundred-year-old!

• 1 year old dog = 16 years in equivalent human age
• 2 year old dog = 22 years old
• 3 year old dog = 31 years old
• 4 year old dog = 40 years old
• 5 year old dog = 49 years old
• 6-year-old dog = 58 years old
• 7-year-old dog = 67 years old
• 8-year-old dog = 76 years old
• 9-year-old dog = 85 years old
• 10 year old dog = 96 years old
• 11 year old dog = 105 years old
• 12 year old dog = 112 years old
• 13 year old dog = 120 years old

What is the senescence threshold?

Indicated in bold, this crucial age for the dog is the pivotal moment when the first signs of old age can appear. However, this threshold is not located at the end of the animal's life but rather in the middle: it therefore still has many good years to live! This is the perfect time to make sure your companion is not prone to conditions that could worsen with age, such as osteoarthritis or diabetes.

If this is the case, the veterinarian will be able to make a diagnosis and, if necessary, carry out more in-depth examinations to offer you a treatment adapted to the situation. In this way, it is possible to block or slow down the progression of the disease. Finally, past the threshold of senescence, it is advisable to regularly check the condition of the teeth and to have a scaling performed if necessary to prevent their loosening, which can lead to infections.
