Your dog's age in years
Note: This conversion is based on current veterinary knowledge. Large dogs age faster than small dogs, so weight is important for accurate results.
No, the 1:7 rule is outdated. Small dogs age slower than large dogs. A 10-year-old Dachshund equals about 56 human years, while a 10-year-old Great Dane equals about 66 human years.
Large breeds grow faster and experience higher oxidative stress. Small breeds have slower cellular aging and live on average 12-16 years, compared to 8-10 years for large breeds.
It depends on size: Small dogs (under 10 kg) are seniors around age 10, medium dogs around 8, and large breeds as early as 6-7 years. Our calculator accounts for these differences automatically.
