Since dogs are mammals with virtually all the same organs as humans, why do they age so quickly in comparison?

Excellent question, and the answer is not known. We do not know what controls the aging process in different mammals that would allow one to live to a maximum of around 100 years while another to live to a maximum of around 20. We have a lot of clues but no real logical sequence of controls that regulate aging. For certain, if we figure it out, it will be a very complex interaction of many genes, RNA's enzymes etc.
