He's vomited yellow/cream coloured foamy bile about 3 or 4

This answer was rated:

Hi he's vomited yellow/cream coloured foamy bile about 3 or 4 times today, he's refusing to eat and he's shivering. We've checked his gums, they are still pink and he appears to not have tenderness on his tummy area. He is a 40kg GSD
Assistant: I'll do all I can to help. What sort of animal are we talking about?
Customer: He's a German Shepherd dog
Assistant: Hopefully it didn't make a mess. Did the German Shepherd Dog eat anything unusual?
Customer: No. He likes to raid the cat litter sometimes but I don't think he ate any today
Assistant: OK. The Expert will know what to do. What is the German Shepherd Dog's name?
Customer: Jake
Assistant: Is there anything else the Veterinarian should be aware of about Jake?
Customer: He's normally very healthy apart from hip dysplasia, which he has Metacam for, but we only give it to him when needed, not regularly.

Hello, I'm Dr. Kara, with over 20yrs of veterinary experience. Please give me time to review & type a full response. I can't take phone calls.

Yellow in the vomit means that the small intestine is refluxing bile into the stomach so that when he vomits you see the yellow color. That isn't normal as bile doesn't belong in the stomach, and it does mean that there is some reverse motility, but it isn't specific for any particular disease process. Vomiting foam simply is a mix of air and stomach/esophageal mucous made when he retches, it is not indicative of any disease process but tells us he is quite nauseous.

In many 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 viral or bacterial infections, chronic pancreatitis, a dietary allergy or sensitivity, inflammatory bowel disease, internal organ failure (kidney or liver disease), ketoacidotic diabetes, a full or partial gastrointestinal obstruction, an abdominal mass placing pressure on her gastrointestinal tract, or infiltrative cancers such as lymphoma.

In some cases though vomiting can be related to a medication. Metacam (generic name Meloxicam) is a nonsteroidal we do use in dogs. It is generally well tolerated but chronic use can lead to side effects including vomiting, diarrhea, abdominal pain, loss of appetite, stomach ulcers, blood in the stools, and acute kidney failure.

While some dogs tolerate a long term dose better than others it is possible he reacted to it. Ideally if this persists he would be seen on an urgent basis today.

If emergency care is not available at home now to try and decrease acid production in his stomach and lessen any possible symptoms you can give either:

1) Pepcid ac (famotidine) at a dose of one 10mg tablet per 15 to 40 pounds of body weight every 12 hours


2) Prilosec (omeprazole) at a dose of one 20mg tablet per 30 to 80 pounds of body weight every 12-24 hours


3) Ranitidine at a dose of one 75mg tablet per 75 to 150 pounds of body weight every 8-12 hours

These are acid reducers that are found over the counter at the drug store. They are the same ones that people take. Any of these can be given as needed for the next several days.

Then if he stops vomiting 6-8 hours after the acid reducer you can offer a bland diet for the next several days. A homemade bland diet is a mix of 1/3 boiled minced white skinless chicken or lean boiled hamburger and 2/3 boiled white rice mixed with some low salt chicken broth to make it easy to lap up and swallow and get in plenty of fluids. Feed small meals frequently.

Things to watch for tonight that mean trouble include continued vomiting, especially blood tinged, dark, black or tarry stools, or frank blood in the stools, lack of an appetite, increased water consumption and urination.

But ideally if this is related to the Metacam he should be seen and started on fluids to try to support kidney function and drugs to avoid ulcer formation. Emergency care is truly his best chance of doing well.

We have at home Gaviscon or Lansaprizole, can we give him either of these?

Lansoprazole is another proton pump inhibitor acid reducer. It can be given to dogs and is dosed at 1mg per pound of body weight every 12-24 hours.

Thank you very much

Glad to help.

After the first 24 hours if he is better I would decrease his Lansoprazole dose to 0.5mg to 1mg per pound of body weight every 24hours. If he's not better of course he needs to be seen.
