Hello I am Dr. Joey. Thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 15 years of experience. I look forward to working with you.
I am so sorry Holly is having these issues. I am not certain the urinary leakage is linked to the vomiting, but this is certainly possible. It may take a bit more testing to separate out if it is linked or not. The trial with Proin sounds appropriate if her urinalysis was normal. And by blood tests I assume she had a complete CBC ,chemistry profile and thyroid check which was all fine.
Did she have X-rays? If not, then these are the definite next step. We are screening her primarily for any sort of intestinal foreign object which may be trapped in her system or bladder/kidney stones/calculi or cancer/tumor. If this is normal and a trial with antiemetic medication does not resolve the problem then endoscopy to view her stomach is necessary as this makes me worried about a primary stomach or upper small intestinal lesion/issue (such as ulceration or tumor or atypical infection). An abdominal ultrasound may also be useful if anything odd is seen on the X-rays or even if not because in the hands of an experienced clinician, this can reveal a tremendous amount about her intestinal tract and abdominal organs. However, I would advocate do the radiographs (X-rays) first.
Have you tried anything yet to help with the vomiting? If not, a starting point you can do at home without expecting any side effects is to use over-the-counter famotidine (20mg twice daily). You can get this (Pepcid AC) at any pharmacy for people.
