Frequently Asked Questions
Is 1 dog year really equal to 7 human years?
No, that is a myth. Dogs age very quickly in their first two years (reaching roughly 24 human years by age 2). After that, aging slows down and depends heavily on the dog's size, with larger dogs aging faster than smaller ones.
At what age is a dog considered a senior?
Small dogs become seniors around 11-12 years of age, medium dogs around 10, large dogs around 8, and giant breeds as early as 6 years old.
