Britt, my Ruppi has pancreatitis. I got her when she was 7, adopted from a rescue as an owner surrender with no previous vetting. Discovering her illness was a first for me, I had 2 other yorkies at the time both healthy aside from one blonde with allergies, so when she had bloody stools and diarrhea with vomiting on Thanksgiving I called our vet and went in. She was medicated and started feeling better fast, we changed our diet (I free feed kibble) and changed our treats.
I still give digestible chews to my dogs, I get flossies and cut them into smaller pieces (1flossie-4 pieces) and supervise while my pups chew. Ruppi would love to gobble up all the flossies from her sisters and brother but since she has the issue I don't let her, and she understands
We had 2 bouts of the bloody stools her first year with us and have been pancreatitis free over a year now, thanks to an amazing vet and easy diet change.
I wish you the best, let me know if you just need to talk.
