In fact I took him to the vet earlier today. She offered no definitive diagnosis but gave him injections of an anti nausea drug and anti biotics (plus dispensed some oral antibiotics for tomorrow onwards) and asked us to monitor him closely and, if necessary, use their OOH services today or tomorrow. That service is some distance away and i was looking for a second opinion as his condition does not seem to have improved since the 1200 consultation. Since then he has vomited four times, the last two being essentially a yellow bile. He has drunk some water but has no interest in food at all and has shown a tendency to hide - eg under a bush in the garden. Can you offerany further advice please?
I will do as you say - and have made a provisional appointment for tomorrow but we will act overnight if he worsens.
