My dog was throwing up bile every morning I called the vet she put her on Pepcid ac she took it for a few weeks today is day 3 wothout it and she just threw up but seems to be more water then bile so maybe she drank too much? If she vomits again should I put her. Back on the Pepcid ? She’s eats and plays everything else seems normal she’s 5 yrs and 11 pounds thank you for your time and advice she also smacks her lips a lot at certain times of the day does that mean anything?

Smacking her lips could be a sign of a dental problem or nausea. Diarrhea and throwing up can be caused by a food sensitivity, dietary indiscretion, intestinal parasites, an intestinal blockage, bacterial infection, viral infection, the weather, food change, stress, etc.  I would fast Kiwi for 24 hours and then put her on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days. If this does not clear up the diarrhea or if the vomiting increases, or if your dog gets lethargic, she needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.
