Dog has diarrhea, won't eat, normal bloodwork. What should I do?
I recommend that your contact your vet's office to schedule a follow-up appointment. Your dog may need further diagnostics to determine the cause of the vomiting and diarrhea. While blood work is an excellent and worthwhile diagnostic tool (and I commend you on having it done), it does have limitations. Blood tests are extremely useful for looking at the overall health of your pet. From the tests, a vet can learn if your pet's vomiting is caused by an underlying medical condtion like diabetes, kidney or liver disease, or an infection. Blood work can also reveal if your pet is dehydrated from the vomiting. Many of these problems may not be obvious on a simple physical exam, but if caught early can be successfully treated or controlled, giving your pet a longer and better quality of life. Sometimes blood work can lead to a definitive diagnosis, but oftentimes blood work results guide us as to what the next diagnostic steps should be (radiographs, ultrasound or more specific blood testing).
