Q. Vomiting what looks like whole food peices, shakiness, looks uncomfortable. Possibly slight fever.
DAVID ELBEZE, DVM, MRCVS
A. He might have eaten something spoiled that is causing this. Withhold food for 12 hours then offer him boiled boneless chicken and rice every 6 hours in small portions. If he is eating and not vomiting, continue with this diet for 2 days.
After 2 days, you can put him back gradually on his normal food.
If he continues vomiting or is not eating, take him to the vet to get treatment as it might be more than a simple gastrointestinal infection (foreign body ingestion, pancreatitis).
