Golden Retriever Lifetime Study - Update From Morris Animal Foundation

Got this poignant email from Morris Animal Foundation today: 

As we approach the 15th year of the Golden Retriever Lifetime Study, we are entering a new, exciting stage every pet owner will appreciate. To date, 386 of our dogs have lived to age 13 or older, including three who have reached the remarkable milestone of 15 years. As a lifelong golden retriever owner, it warms my heart to see these dogs thrive. As a veterinarian and epidemiologist, I am eager to leverage this unique dataset to understand what sets these “super-seniors” apart. After all, that is our ultimate goal: we don’t just want dogs to avoid cancer, we want dogs that remain healthy and vibrant well into their golden years.

To capture the shifting challenges these dogs may face as they age, the Study utilizes supplemental surveys that participants can opt into every six months. These provide vital data on mobility and cognition. This initiative began when most dogs in the Study were approximately 8 years old and is rapidly becoming a robust dataset that will aid researchers for decades. Current research suggests dogs fall into two categories: "cognitive maintainers" and "cognitive decliners." Our data is uniquely positioned to help us identify the specific factors that contribute to prolonged cognitive health.

Because the Golden Retriever Lifetime Study is longitudinal, scientific interest has accelerated alongside the Study’s progress. While we have sadly said goodbye to 1,780 heroes, the information they contributed from puppyhood onward is of historic importance. As I write this, more than 100 studies have leveraged our data to investigate a wide variety of health topics. We recently closed our annual call for canine research proposals, and of the 142 pre-proposals submitted, 21 plan to incorporate Study data.

While the Study’s evolution into aging is exciting, our primary objective — to make progress against canine cancer — remains unchanged. The Foundation recently invested in two cancer studies that showed promising initial results. Both successfully identified genetic regions related to hemangiosarcoma and histiocytic sarcoma, respectively. Researchers are now building on these findings using Study data, which could lead to life-saving genetic tests. These are just two examples of the many promising studies currently underway that have the potential to change the future of canine health.

From all of us at Morris Animal Foundation, thank you for making this work possible and supporting the research that will help dogs run, play and be with us to create more memories well into their golden years.

Please keep up the good work; your team will always have wishes from Max and I.  

I said this when Max had cancer and I am saying this now - a lot of insights will come from this study and the Dog Aging Project which will help Sapiens although my moronic species refuse to give data. 

Researchers need a lot of data from healthy people to understand what it looks like not having cancer - a fundamental machine learning common sense.
