The real science of puppy aging Subscribe to support optimistic science and tech videos! Meet Thor. He’s a 10-pound Australian Shepherd and, objectively, the cutest dog to ever live (except yours, of course). Thor is 8 years old, which means that he is likely about halfway through his life. I on the other hand am probably about a third of the way through mine. I hate that math. It seems cruel that we live so much longer than our best friends. What can we do to help dogs live longer? That’s where this video begins. Along the way, my research took me on a journey to better understand what aging is, human and dog longevity research, how dogs and humans age differently, and why “dog years” aren't real. I met Celine Halioua, founder of a company called Loyal, which is conducting large-scale dog longevity research. And I spent some quality time with Thor. But the best part of this video is that YOU submitted your dog videos and photos! This video is dedicated to your dogs: Poppy, Cleo (oh, hey!), Alexa, Pickles, Bree, Tuffy, Whitey, Dakota, Callan, Annie, Lonzo, Belle, Momo, Nelson, Yolie, Achilles, Yondu, Jasper, Ginny, Arya, Goldie, Macho, Mochi, Bombon, Pepe, Cheeseburger (omg), Ellie, Hagrid, Leia, Mosley, Chillie, Mery, Azure, Data, Luna, Dobby, Ketch, Sem, Hershey, Kobe, Penny, Ari, Lou, Browser, Molly, Pia, Jack, Pocky, Alphonse, Banjo, Sandy, Simba, Maha, Chip, Titus, Dougal, Apollo, Lucky, Mister, Mouse, King, Meda, Yoshi, Bacon, Mia, Sherry, and Macy.
