Who wouldn’t want to extend a beloved pet’s life? Dogs are trusted companions for countless households in Canada and the United States, and the idea of preserving their health over time resonates with many owners. A California-based company focused on canine longevity is preparing to bring a new pill to market that aims to lengthen healthy lifespans in dogs. The enterprise is currently evaluating two versions of the same product to determine the most effective approach.
Loyal, a San Francisco–based company, has conducted extensive research into how aging affects dogs across breeds and ages. In recent years, the team evaluated data from roughly 500 dogs of varying sizes and backgrounds from across the United States to understand aging patterns and health outcomes more clearly. This work helps guide the development and testing of the two product candidates in the trial phase.
Two products are in the trial stage. LOY-001 is designed to be administered periodically, every three to six months, with dosage considerations tailored for larger dogs that typically have shorter lifespans than smaller breeds. LOY-002 aims to promote healthy aging for dogs at a certain age, across many sizes and breeds. The overarching promise is that this product improves metabolic fitness and could extend the number of healthy years a dog enjoys. These goals reflect a broader focus on longevity and quality of life for canine companions. [Loyal study]
In 2023, LOY-001 began pilot testing in dogs, with a planned market introduction around 2026. LOY-002 is anticipated to arrive sooner, potentially in 2024, as decisive testing on its safety and effectiveness is advanced. [Loyal evaluation]
The effect of epigenetics on dogs
Current studies are increasingly exploring how epigenetics influences aging in dogs. Epigenetics examines how behavior and environment can alter gene activity. Unlike classic genetics, which focuses on the DNA sequence itself, epigenetics investigates the processes that switch specific genes on or off. Loyal describes this concept as a set of handwritten notes that guide which parts of the instruction manual to read closely and which to set aside. [Loyal]
The executive team notes that their research aggregates data from thousands of dogs to craft health measures and medicines that support longer, healthier lives. DNA methylation, one form of epigenetic modification, helps control which genetic regions are active within a cell. [Loyal]
Recent findings show that DNA methylation patterns shift as an organism ages. These changes correlate strongly with aging, and researchers have developed computational models called epigenetic clocks that can estimate an animal’s age based on methylation patterns alone.
Loyal emphasizes that its team builds advanced tools from a unique canine epigenetic dataset to predict health trajectories and inform drug development. The organization suggests that owners may soon access insights through tests that reveal health and lifestyle information or through faster therapeutic options for their dogs.
If successful in extending canine health with anti-aging pills, it is possible that insights gained from dog research could eventually inform human aging strategies, since the underlying biology of aging is shared across species.
