I can't remember how many times I've been through this. My Tess seems to have very sensitive digestion. I always worry anytime she.vomits because it can progress to the bloody diarrhea quickly. The first time it happened I was a complete mess, thinking that she had internal bleeding. Now Im somewhat casual about it! I watch her carefully and don't delay in getting her treated but no longer panic. It sounds like you've done everything right for Misty. Has the vet had her on a bland diet? I usually give mine boiled rice mixed with baby food and then gradually reintroduce her regular food. Good luck.
