Frequently Asked Questions
Why is the 'multiply by 7' rule wrong?
Dogs and cats reach sexual maturity in their first year (equivalent to a human teenager). Cellular aging slows down in mid-life and accelerates again in large breeds, making logarithmic models much more accurate.
Why do smaller dogs live longer than giant dogs?
Giant breeds grow rapidly from puppyhood, putting immense demand on cellular replication and cardiovascular systems, leading to earlier onset of age-related conditions.
