Big Red needs your help!!

This 14 year old gelding has been living with an elderly couple who are no longer physically or financially able to provide for his care.  We are looking for funds to provide him with hay, supplements, grain,  medication to care for rainrot (a fungal infection resulting from no shelter or blanketing during inclement weather), worming, a visit from a veterinarian, a visit from a farrier to care for his feet, 2 blankets he can wear to protect him in bad weather, and to build him a shelter.  Our goal is to bring him back to good health and then to rehome him.   Thanks to any and all who are able to help.
