American Humane Association is not able to provide financial assistance to individual pet guardians.
You may qualify for funds available through http://www.imom.org/ for emergency situations. Also, ask your veterinarian about low-cost veterinary services in your area. Some clinics work on a sliding scale based on income. And some universities have veterinary programs where high-level veterinary students perform procedures under the supervision of licensed doctors, often at a greatly reduced rate. Veterinarians may also offer long-term payment plans for expensive procedures.
