Most people would do just about anything to extend the life of their pet . And right now , researchers with the Dog Aging Project are testing a anovulant , rapamycin , that could do just that .
It may sound far - fetched or too effective to be rightful , but research worker are investigating whether a pill could serve our dogs live longer .
stave at the University of Washington’sDog Aging Projectmay be help oneself us get one step closer to making this dream a world . The team is running a nationwide field of study involving almost600 dogs , test the life - cover potential drop of the drug rapamycin .

Usually , humanity take rapamycin . It ’s empower by the U.S. Food and Drug Administration ( FDA ) for human being who ’ve undergone pipe organ transplants . The drug suppresses the immune system to prevent it from assault donate reed organ . But rapamycin , also known as sirolimus , may also aid slow up the canineagingprocess , potentially adding eld to our dogs ' life-time .
Could Our Dogs Live 3 Years Longer?
The cogitation ’s lead researcher , Matt Kaeberlein , PhD , tells Daily Paws rapamycin point the biology of aging in every living thing it ’s been tested in , from single - celled yeast to mice . The potential key : smaller doses than what humans take to preclude transplantation rejection .
" Rapamycin seems to have the ability to ' reset ' resistant procedure by reducing the addition in continuing inflammation that goes along with aging , " Kaeberlein says . " This also seems to have benefits beyond the resistant arrangement in all form of tissues and organs . "
In black eye , rapamycin seems to reverse geezerhood - related operable decline in the heart , brain , ovaries , and oral cavity , Kaeberlein says . It also appear to supercharge the immune system ’s ability to detect cancers and fight off viruses like the flu and COVID-19 .
In the current study , researchers theorise that the blue dose of rapamycin may increase the lifespan of dogs by up to three years . Kaeberlein says this estimation is based on experiment in science lab mice , where rapamycin increased average lifespan by up to about 25 per centum .
If that percentage is employ to a dog with a 12 - year lifetime , the bow-wow accept rapamycin could theoretically dwell to 15 . Of of course , the drug has been test on mice , so it ’s unknown whether it will have the same effect on dogs , Keaberlein says .
As if the prospect of a new life - extend drug for dogs was n’t exciting enough , it might also work foraging catsbecause the biological science of aging is so similar among many species , Kaerberlein says .
Questions Remain
So this is sure call , but many questions stay on regarding rapamycin ’s impingement on aging , including which heel can take it and when .
Kaeberlein says he ’s not mindful of any biologic ground that would make dogs more or less potential to benefit from it , though some dog may respond differently to rapamycin because of their genetics . As for when to go look at it , Kaeberlein says the sweet spot might be around 6 or 7 year sure-enough for larger dogs and 9 or 10 years old for smaller dogs — ground on the mice experiment .
And even if the study proves successful , it ’s unclear how long it will be before you may get a postponement of rapamycin for your aging pets ( or yourself ) .
Kaeberlein says their trial wo n’t directly lead to rapamycin ’s FDA approval for seniority in dogs , although it certainly could help . He total that the field of study did n’t seek FDA approval for rapamycin because it ’s already approved for human function . Plus , physicians and veterinarians can already order it for off - recording label ( non - O.K. ) use .
But even with all these unknowns in swordplay , Kaeberlein indicates there ’s undecomposed reason to be affirmative .
" If our trial shows compelling grounds for beneficial effect and picayune in the way of side issue , I mistrust many veterinarians will become more well-off prescribing it for owner who request it , " he says .
