Dog aging is irrelevant. It's well-documented that dogs have a faster biological aging process due at least in part to the telomere caps on chromosomes which protect the DNA. Dogs lose these caps at a rate around ten times the human rate.
I remember seeing discourse recently saying telomere shortening is a side effect more than a cause of aging as a function and happens as a function of DNA damage. Important to consider
