FAQ
Is this veterinary advice?
No. It is a general age comparison. Ask a veterinarian for health, diet, or treatment decisions.
Why does dog size matter?
Large dogs often reach senior stages earlier than small dogs, so the estimate changes by body size.
Does breed change the result?
Yes, breed and individual health can matter. The calculator gives a broad practical range, not a diagnosis.
