Poor darlinn, he is having a serious diarrhoea now, since last night, had been going in and out from the toilet for more than 10 times, what can I do now?

He has no appetite for any food, forced him to drink more water to rehydrate himself. Given him two different kind of diarrhoea medicines, one in the morning and the other one in the afternoon, but both of that doesn't seem to have any effectiveness to him. What else should I give to him?

May bring him to refer to the GP if his condition doesn't turn any better, but it is already 6pm now, and today is Sunday, where to get a GP at this time?

*Pening*
