My 3 year old dgs has been poorly for a few days high temp,lethargic and no appetite. Gp has prescribed antibx and he is having calpol/ibuprofen at appropriate intervals. When I collected him at 9am his dad said he hadn't weed since the early hours and wasn't drinking much at all. It is now noon and dgs has just fallen asleep. His last temp was 38.3. He still says he doesn't need to wee. I have persuaded him to drink most of a tiny carton of apple juice and a few sips of water. Please tell me what if anything I should be doing. Should I wake him to give more Calpol? How much does the not weeing matter? At what point do I call a doctor or the little one's parents?
