I have a mare that has contracted EPM. Right now we are giving her antibotics twice a day. We were going to buy the tube "Marquis" that is made for EPM but you have to buy for a 1000 pound horse and mine only weighs 200 pounds. Is there anyone out there that nows of a vet or has an extra tube of Marquis around. If not we have to give the mare her antibotics for three months instead of the one month. I was hoping to find it so she would not have to limp around for the extra two months.
