We took Holly to the new vet this morning, and he was GREAT! He looked at her long history of diarrhea and vomiting, as well as itchy skin, sneezing etc. He said it is likely there is an allergy component, as well as something else that's causing the digestive issues. He said she has symptoms that could represent a lot different issues, and he did blood testing to try and narrow it down. One possibility is that she has a pancreatic insufficiency so her body isn't able to break down the food like it should. He also said she's displaying symptoms of Addison's Disease although he said this is rare. He was surprised our old vet had never done blood testing to rule these things out before starting food trials for food allergies. He gave us a powder to help her digest food, and recommended we try TOTW since we have already tried California Naturals and Natural Balance with no luck. I did not hear the words Science Diet one time, yay! I felt very good about our visit, I feel like we are a team and he really wants to help us get to the bottom of this. He said we may need to go to an allergy specialist at some point but he would like to get the diarrhea and vomiting under control so she can start eating more regularly first. We will get the results of the blood test in a week or so, I will keep you all posted. Thanks for all of the kind thoughts and support!
