Kiko is very sick...Help!
Kiko has been very sick for the last 4 days. His symptoms includes vomiting, loss of appetite, lethargic, shivering, and today he had black stool. We've taken him to the vet 2 days ago. The vet ran X-ray and blood work...both came back negative except for dehydration. So they gave Kiko a shot of antibiotics and an injection of fluid. they also gave him Cerenia (prevents vomiting). He got better for a day, then we're back to square one again. We racked up good amount of $$$ without any diagnosis from the vet. Any ideas what this could be? Thanks in advance.
