Laura Mclain, a licensed doctor from this hospital, prescribed 1mg of Metoclopramide per 8 hours to my sick 1kg guinea pig. Immediately after taking the medicine, my guinea pig started to struggle and passed away after half an hour (torturing hour).
I later found that the suggested dose for animal is 0.1 to 0.2 mg per pound, which means the dose Laura Mclain gave my piggy is 2.3 times over the upper limit.
