In 1999, Peters and Mary Tyler Moore co-founded Broadway Barks, an annual animal adopt-a-thon. Each July, Peters hosts the Broadway Barks event in New York City. Peters held a concert, "A Special Concert for Broadway Barks Because Broadway Cares", at the Minskoff Theatre, New York City, on November 9, 2009 as a benefit for both Broadway Barks and Broadway Cares/Equity Fights AIDS. The concert raised an estimated $615,000 for the two charities. Also in support of Broadway Barks, Peters has appeared on the daytime talk show "Live With Regis and Kelly".
