The myth that a dog year equals seven human years persists stubbornly. And indeed, many dog owners still believe that their two-year-old fur nose is actually 14 and their eight-year-old companion is basically 56. In fact, this way of calculating a dog's age is fundamentally wrong. How old your own dog is now actually in human years, something must be answered in a more differentiated.
The Difference between big and small dogs – and consequently also the basis for the correct calculation of age – is the speed with which the aging process progresses. The bigger the dog, the faster his body ages and the faster his cells divide. This is one of the reasons why large dogs in particular have a certain risk of developing tumors. Thus, an eight-year-old Newfoundland is mathematically much older than a dachshund at the same age. Setting a lump sum of seven years for all breeds leads to a result that does not meet the individual requirements.
The following table shows how old a dog actually is in human years:
