Hello, my name is***** and I have over 20 years of experience as a veterinarian. I am sorry to hear that your girl is vomiting water after drinking. She is likely dehydrated because she has been vomiting, thus the drive to drink even though nauseous, but if even water is making her vomit you need to take it away from her until she stops vomiting.

In most cases vomiting is triggered by eating something they should not, too much table food, too many treats or something they find outdoors.

More serious causes of vomiting include toxin ingestions, systemic viral or bacterial infections, esophageal reflux, a dietary allergy or sensitivity, inflammatory bowel disease, internal organ failure (kidney or liver disease), or a full or partial gastrointestinal obstruction. If she is a middle aged or older then an abdominal mass is also a possible cause.

In a young dog, especially if she never finished her vaccine series, a viral infection such as parvo virus, toxin ingestion, or a foreign body leading to a partial or full gastrointestinal obstruction would be the most likely cause of inability to keep even water down.

Because she is vomiting even water ideally she would see a veterinarian now.

If that isn't possible for whatever reason there are some things we can try at home, but if she's not improving quickly she should see a veterinarian for an examination, some diagnostic testing, intravenous fluids and injectable medication to settle her stomach.

To try and settle her stomach you can give either:

1) Pepcid ac (famotidine) at a dose of one 10mg tablet per 20 to 40 pounds of body weight every 12 hours

OR

2) Prilosec (omeprazole) at a dose of one 20mg tablet per 40 to 80 pounds of body weight every 24 hours

These are acid reducers and may help settle her stomach and get her feeling better and hopefully get her appetite back. They are very safe and can be used for several days.

I would pick up all food for now and water for a couple hours to allow her stomach to settle after the acid reducers.

In a couple hours when you give her water make sure it is in small amounts only. If she drinks too much too quickly that can lead to vomiting. You can also offer ice cubes to lick. To get some electrolytes in you can offer her a 50:50 mix of pedialyte and water.

If there is no vomiting for 12 hours offer a bland diet of 1/3 boiled, minced, white skinless chicken or boiled, lean hamburger and 2/3 boiled, white rice mixed with some low salt chicken or beef broth to make it easy to lap up and swallow. If she refuses that you can offer a little meat baby food. If she refuses both then don't push it, she needs veterinary care.

But if things go well and she does eat and doesn't vomit feed her the bland diet for 2 to 3 days then slowly start to mix back in her regular food, a little more at each meal. It should take about 5 to 7 days to slowly convert her back to her regular diet.

If she continues to vomit even with the acid reducers, runs a fever (more than 103F rectally), or has a lower then normal temperature (less then 99F), has a tense painful belly or if she refuses to eat she should see a veterinarian for an examination, diagnostics, injectable anti-nausea drugs intravenous fluids and supportive care.

Please let me know if you have any further questions.
