No, the 7:1 ratio is a myth. Dogs age much faster in their first two years (about 15 human years in the first year), then slow down. Breed size significantly affects the aging rate.
Small breeds typically live 12-16 years, medium breeds 10-14 years, large breeds 8-12 years, and giant breeds 6-10 years.
It depends on size: small dogs become senior around 10-12 years, medium dogs at 8-10, large dogs at 6-8, and giant breeds at 5-6 years.
