San Francisco-based startup Loyal, founded by Celine Halioua, is developing canine longevity pills aimed at extending dogs' lifespans by targeting metabolic and hormonal imbalances before they lead to disease. The company has raised $135 million from top investors and anticipates receiving its first conditional approval from the U.S. Food and Drug Administration (FDA) next year. This initiative addresses the relatively short lifespans of dogs, with family Labradors typically living up to 14 years and larger breeds like Bernese Mountain Dogs often reaching only around 9 years. Loyal is currently conducting clinical trials to support regulatory approval. Separately, Fountain Life, a longevity company associated with Tony Robbins and Peter Diamandis, has raised $18 million, highlighting growing investor interest in longevity-focused ventures.
