My dog is throwing up green foam. What's the cause and is it serious?

There may be vegetable bits inside and any food that could turn the stomach content into green color. Such a liquid and profuse vomiting is quite concerning, A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed.

It is concerning that he has thrown up so many times in just a few hours. I would most certainly have him seen by a veterinarian ASAP. He may have stomach inflammation or a more serious issue like a gastrointestinal obstruction.

This much vomiting is not normal. Tifa needs to be seen by a vet for an exam as soon as possible. Please understand that vomiting is a very non-specific symptom. Almost anything can cause vomiting. Your vet needs to do an exam and maybe some testing (blood and/or x-rays) to figure out what is going on. I'm glad she is acting OK and you don't think her abdomen is painful, but no offense, you are not properly trained to palpate the abdomen correctly. The vet will need to do that and will be able to assess pain as well as feeling the integrity of the organs. The stomach itself is up under the ribcage and cannot be palpated. Dogs can act seemingly normal but still have something wrong underlying.

Oh no, that's not good! It's quite serious when a dog can't even keep down water, and it can be caused by a severe GI illness, pancreatitis, a foreign body, or eating something rotten. This requires an immediate vet visit so the cause of the vomiting can be diagnosed and treated. Please take your dog into a vet now.

Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting can be observed with conditions such as gastroenteritis, pancreatitis, dietary indiscretion, gastrointestinal foreign body ingestion and obstruction, among other possibilities. For this reason, I highly recommend that you have Diesel evaluated by a veterinarian for further assessment and treatment as soon as possible as I am afraid he is likely becoming dehydrated. They would be able to check for these possibilities and also check his hydration status and give him medications to make him feel better. Good luck!

Poor Coki! I would be worried too, as having blood in the vomit can have very serious causes including GI ulcers, eating something toxic, GI tumors, bacterial or viral infection, a foreign body, or clotting disorders among others. I would have Coki seen by a vet right away for a physical exam, blood tests, urinalysis, and possibly x-rays. Once the cause of the vomiting and blood is diagnosed, the vet can start treatment.

This is likely to be due either to dietary indiscretion or possibly to a infective gastroenteritis. I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, more vomiting, lethargy or inappetence.
