Scientific Results: An open science study of ageing in companion dogs

Published on July 15, 2026

The key takeaway for families with dogs is that ongoing research into dog aging can lead to significant improvements in their pets’ health and longevity. By staying informed about new findings from the Dog Aging Project and working closely with their veterinarians, dog owners can help ensure their pets live happier, healthier lives.

Dog and Human Genetics: Similarity and Difference

Published on July 26, 2022

Did you know that dogs and people share over 17,000 special genes called orthologs? Each pair of orthologs is derived from the same common ancestor via vertical descent (speciation) and they tend to have similar functions. They are one of the main reasons why your pup is such an invaluable comparative animal model for studying human health. In fact, humans and dogs have numerous similarities even in those parts of the genome that aren’t genes (the noncoding part of the genome). When it comes to better understanding human health, your pup is our best friend!

Fountain of Youth: Understanding inflammaging and why we age

Published on May 12, 2022

Getting older can take a toll on the body. As we age, we may experience more aches and pains, loss of memory, or changes in our vision and hearing. With increasing age, there is also an increased risk of developing chronic diseases. Studies show that nearly 80% of Americans over 65 have at least one chronic disease and 50% have at least two chronic diseases.
