The American Society for the Prevention of Cruelty to Animals (ASPCA) has announced the participants in its third annual “Help a Horse Day” grants contest.

The nationwide competition of equine rescues and sanctuaries is designed to raise awareness about the year-round lifesaving work they do to care for local at-risk horses who’ve been abused, neglected or find themselves homeless. In honor of the ASPCA’s 150th anniversary celebration this month, the ASPCA has teamed up with “2 Broke Girls” actress and horse advocate Beth Behrs to spread the word about the contest, which has been expanded to include a total of $100,000 in grant prizes. This year, 191 groups will be hosting events across 42 states during the weekend of April 22-24 as they compete to win a grand prize of $25,000.

“The ASPCA Help a Horse Day contest has grown exponentially over the past few years, and we are excited to celebrate our 150th anniversary by providing even more grants to the dedicated equine rescues and sanctuaries that step in to care for abused or neglected horses and give them a much-deserved new lease on life,” said Jacque Schultz, senior director of the ASPCA Equine Fund. “We are proud to welcome Beth Behrs to the contest this year and we applaud her efforts to raise awareness about wonderful horses available for adoption around the country.”

Behrs said, “I recently adopted my horse, Belle, from a California sanctuary, where I was able to see firsthand the tireless efforts that go into rehabilitating and caring for at-risk horses. It’s inspiring to see the creative events being planned around the country in celebration of the ASPCA Help a Horse Day contest, and I am honored to lend my voice to equine protection and to help recognize these everyday heroes for their life-saving work
