How old is my Boxer in human years?
Use the calculator above with your Boxer's current age (in years or by date of birth). The result follows the AAHA non-linear curve adjusted for large-breed aging speed.
When is my Boxer considered a senior?
From about 8.5 years. Vets count a dog as senior in the last quarter of its expected lifespan (AAHA), and for the Boxer that comes from the breed's median lifespan in a 2024 study of UK dogs. Your vet may suggest check-ups twice a year from then on.
