Dogs mature rapidly in infancy and decelerate later. A 1-year-old dog has reached sexual maturity, unlike a 7-year-old human.
💡 ACTION:
Linear age multiplying fails modern veterinary understanding.

UCSD formula: 16 * ln(Dog Age) + 31. Epigenetic chemical markers on canine DNA match human genome aging non-linearly.
💡 ACTION:
A 1-year-old dog equals a 31-year-old human; a 4-year-old equals ~53.

Because aging accelerates after 7 calendar years, biannual blood panels catch kidney and thyroid decline early.
💡 ACTION:
Run routine SDMA kidney and thyroid screens annually after age 7.
