- Join us for the 3rd annual Run Your Happy Tails off Race and Festival Benefitting Happy Tails Pet Therapy, a metro Atlanta non-profit organization. Founded in 1991, our 300 active volunteers make more than 1,700 assisted therapy visits annually serving over 15,000 individuals with emotional, cognitive, and special needs throughout the year. This family and dog friendly event will help us continue sharing the unconditional love of their pets with those in need.
