It started on Friday 18th with bad diarrohea (sp.?) all day, then he seemed OK apart from lack of appetite, then on Tuesday he had bad runs again. Since then still no appetite, nasty yellowy poo and he was sick on Thursday night. Doctor seems unconcerned. Told me on Friday he thought he'd recover over the weekend, but he still looks pale, tired and still isn't eating much. He's also lost weight and I'm quite worried about him.
How long can these things last? He is drinking loads but eating very little.
