As the realization of the positive power of pet therapy started to grow, the organization established a framework and certification process for people to provide pet therapy to others. Love on a Leash® was incorporated in 1995 as a 501(c)(3) charitable organization based in San Diego County, California. Over the years, Love on a Leash® has expanded beyond Southern California to nearly every state in the USA. As of April 2022, there are over 2,400 Love on a Leash® members, volunteering as Love on a Leash® therapy teams with their dogs, cats, and/or rabbits. In many communities, volunteers have formed chapters to help coordinate visits and provide support, motivation, and social interaction.
