My dog won't eat, is throwing up, and has diarrhea. Is it serious?
Based on the information provided, I'm not clear as to how long the loss of appetite and other symptoms have been going on, but I'm assuming more than 24 hours. It sounds like your big man normally has a very healthy appetite. The symptoms do seem pretty vague, but if they are becoming more frequent, it is definitely time to see your veterinarian. Lots of things could cause Cash to stop eating; everything from a virus, to a blockage from something he ate, or kidney or liver disease, and more. Your veterinarian will likely want to start checking some bloodwork and maybe getting abdominal xrays. The previous episode of diarrhea may or may not be related, but I think it is time to look into this further. In response to your question "could this be something serious", that is harder to answer. In short, yes it could, but I hope it isn't. Only with a full exam and some testing will your veterinarian be able to answer that fully. I hope your Johnny Cash is on the mend soon.
