Upon noticing symptoms of diarrhea, the first step should be to assess the goat's overall condition. Ensure that the animal is hydrated, as dehydration is a significant concern. Oral rehydration solutions that contain electrolytes can be beneficial. These solutions help restore lost fluids and maintain electrolyte balance. If the goat is severely dehydrated, subcutaneous or intravenous fluids may be necessary, and this should be done under veterinary supervision.
