How to Slow Aging (starting with your dog)

right off the bat, off your introductory statement - I find the premise offputting - I am thankful to my childhood cat for being my first friend/family to pass... It helped me learn about loss. I don't think keeping them alive any longer really changes anything. I would rather see us continue rigorous study on mice, and when reasonable and sustainable, primates - where cellular longevity research is concerned. These animals provide us with invaluable data for our own uses. Prolonging dog/cat life sounds pretty useless and is just a very marketable commodity. Even the stoutest pet lovers end up getting a new cat/dog within a few years. Loss is part of life.
