Bryan Johnson shifts his longevity quest to his new guard dog

During a San Francisco longevity event, entrepreneur Bryan Johnson revealed that his newly adopted Belgian Malinois, Katara, will become the subject of an extensive anti-aging experiment. Johnson, known for his “Don’t die” mantra aimed at human lifespan extension, said Katara will receive the same rigorous biometric tracking and therapeutic interventions he documents for his followers. He emphasized that the initiative is personal and not tied to a new company launch.

Johnson criticized typical commercial dog food for containing harmful compounds and suggested that improving canine nutrition could be a straightforward health boost. He pointed out that regulatory pathways for veterinary drugs are shorter than for humans, enabling faster testing of novel treatments. Existing firms like Loyal, which seeks FDA-approved longevity drugs for dogs, and Rejuvenate Bio, which pursues gene-therapy solutions, were cited as examples of the growing field. Johnson believes many pet owners will prioritize their dogs' health even more than their own.
