Rejuvenate Bio launches to help dogs live longer, healthier lives

This 2019 report described a company developing gene therapy, a treatment that adds or changes genetic instructions, for dogs. The planned treatments aimed to target age-related problems such as heart disease, diabetes, and obesity. The company had not yet shown in a controlled study that treated dogs lived longer or healthier lives. The supporting research mainly involved laboratory work and mice, which does not directly apply to humans or prove the treatment works in dogs.

What this means for you: This was an early company announcement, not proof that a product works. You can ignore it when making health or pet-care decisions until well-designed dog studies report results.
