Frequently Asked Questions
Is a dog year really seven human years?
Not exactly. The old "multiply by seven" rule oversimplifies how pets age. Both dogs and cats reach about 15 human years at age one and about 24 at age two, and the rate after that depends on the species and, for dogs, on their size.
Why does dog size matter for the calculation?
Small dogs tend to live longer and age more slowly after the first two years, while large and giant breeds age faster. A large dog of the same age is therefore older in human terms than a small dog.
When do pets become seniors?
Most vets consider cats and small dogs seniors around age 10 to 12, medium dogs around age 9 to 10, and large or giant breeds as early as 6 to 8, which on the charts corresponds to roughly 56 to 64 human years.
