My dog has been vomiting once or twice a day for about 3-4 weeks. This usually happens when she drinks a lot of water. It rarely happens when she eats. When she vomits, it is just the water and whatever undigested food she has eaten within the last couple of hours. The vomit is clear - not yellowish or any signs of blood. She is very alert and energetic and has no other symptoms suggesting any other health problems. What would you suggest?
