I need advice. I have a mature doe that has had scours for the past three weeks. At week two we gave her 1cc of Draxin followed 3 days later by another 1 cc of Draxin. With no change the following week we gave her 1cc of Cydectin. We also started the pen on Safegard for 3 days. We will begin another 3 days of Safeguard tomorrow. There is still no change in the scours. Any advice would be appreciated.
