Of course not! I think with most vets and doctors they start with the most "probable" which usually translates to the most "common". Reading the description does make me wonder.
I think I want to know what the cut off point is for me to bring this back up with my vet (or search for a new one) if Ava keeps going with bloody diarrhea. When should I request blood work? What kind of questions should I ask? I want to do my due diligence in regards to Ava's health. So any scenarios or possibilities, no matter how scary, is appreciated.
