We are a low-cost, nonprofit spay and neuter clinic serving low income families and animal rescue organizations in the greater Columbus area. Our mission is to improve the quality of life of shelter animals and companion animals of low income families by providing affordable veterinary care, and to help reduce the homeless pet population through spay/neuter programs. SOS of Ohio was established in 2007 by Dr. Melanie deHaan as a mobile mash clinic serving humane societies and area shelters. In February of 2009, SOS of Ohio was reestablished in its current form as a Humane Alliance style, high-volume, stationary clinic serving both rescue organizations and the general public. While our primary focus remains spay and neuter, we also offer other low-cost veterinary services, vaccinations and treatments at the time of surgery.
