Dogs age around 6-7 times faster than we do which is where the common multiplier of ‘7 dog years = 1 human year’ comes from. Because dogs live and die much faster than humans it is easy to overlook the ageing process and how quickly it occurs. Although dogs life expectancies are 6-12 times shorter than humans, the demographics of dogs (living conditions, diet, weight and exercise) can change considerable with aging. Dogs develop the same age-related changes and disease as we do making them directly comparable to us. Afterall, dogs share more ancestral genomic sequence with humans than rodents do!
