My dog keeps throwing up yellow liquid. Why is this happening?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered

Milo keeps throwing up yellow liquid and it’s happened before but I thought he just ate too quickly but today he kept throwing up all around the house. This morning it had hair in it, but now it’s just yellow liquid. We ran out of food yesterday so we had been feeding him some plain chicken until we bought new food. Do you know what may be causing this?

Poor Milo. It could be a number things causing this including a severe GI illness, eating something rotten, a foreign body, pancreatitis, or an illness like kidney disease. It's concerning he's been throwing up all around the house today, so I think it's best he sees a vet now. I'd recommend taking him into one immediately.

Oh no, poor Buddy! It's not good that he's vomiting in the middle of the night. The yellow liquid is likely bile acid, and he could be vomiting due to a GI illness, a foreign body, or GI tumors among other causes. It would be best for him to see a vet for this, and I would take him into one in the morning. The vet can diagnose what is causing him to vomit so he can be treated.

There could be a couple of things causing Prince to vomit including GI illness, parasites, eating something rotten, a foreign body, and pancreatitis. Vomiting seven times in 30-40 minutes is quite a lot, and this requires an immediate vet visit. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck.

Hi, and thanks for your question.
These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). 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.

My dog threw up antler pieces and yellow bile. What should I do?

Poor Milo! If he is otherwise acting normal then you could withhold food for the day and see if the vomiting resolves. If so, then you could try a small amount of a bland diet, boiled chicken and white rice, this afternoon. Continue feeding the bland diet for a few days and the gradually transition back to his regular food. If the vomiting continues and/or he becomes lethargic then he needs to be examined by a vet for treatment. Your vet can take an x-ray, if needed, and then prescribe medications to help control the vomiting and make him feel better.

My dog is throwing up yellow bile and food. What should I do now?

If your pet has vomited this much in the past 45 minutes I would be very suspicious of a foreign body or a very intense dietary indiscretion (eating something he shouldn't have). I would recommend you start supportive care (like Famotiidne 05-1.0mg/kg every 12 hrs and a bland diet like Purina EN Gastrointestinal canned food OR boiled plain chicken and rice or cottage cheese. However there is a big possibility that this could have been a toxicity and if any more symptoms start to arise (such as ataxia (staggering) or shaking, crying out) then I highly recommend you seek a personal veterinarian for a physical examination and further diagnostics. - Dr. H

My dog keeps vomiting yellow liquid and is very tired. What to do?

It sounds as Dexter is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

My cat and dog are both vomiting yellow liquid. Should I worry?

This is not specific to any disease, but indicates that something is either directly upsetting their stomachs, or generally making them feel nauseous. The yellow color is due to bile staining which doesn't tell much other than they are vomiting on an empty stomach. One possibility is that they ate something they were not supposed to like medication, a chemical (i.e. antifreeze), raw meat, or a plant (i.e. lilies). Vomiting is often the first signs of an exposure to a toxin, so I recommend checking if it's possible for them to have eaten anything other than their normal diet. Vomiting and nausea can also be due to an infectious disease, organ failure, or imbalance in the blood. In order to narrow down the possibilities, you would have to take them to the vet for an evaluation. This doesn't appear to be an emergency, but if they are acting very depressed and is vomiting continuously, then it would be best to take them to the vet sooner rather than later. If they are otherwise acting normal, then it's important to not give any food for the next eight hours, but make sure they have plenty of clean water available. If they are not vomiting in eight hours, then only feed a small amount of food (about 1Tbsp.). If they keep that down, then you can feed a little more in two hours. If the vomiting is continuing tomorrow, then it's best to take them to the vet for an evaluation. For more information about vomiting, I recommend you read the article at the link below. https://www.petcoach.co/article/diarrhea-vomiting-in-dogs-when-to-call-your-veterinarian/ If you have further questions or need further clarification, then you may consider having an online consult with one of our vets on Petcoach. This way, you can send unlimited pictures and have a text conversation with a vet. I hope that helps and they get better soon.

Why does my dog vomit yellow bile often? What could be the cause?

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting is sometimes seen with conditions such as inflammatory bowel disease, dietary indiscretion, pancreatitis and chronic kidney disease, among many other conditions. Given Mugsy's young age and the fact that he is otherwise doing fine and this is sporadic, dietary indiscretion appears more likely. It may be something as easy as just changing his diet to something that he can tolerate better. However, an examination by a veterinarian as well as minimal diagnostic data would be needed to rule out more concerning things. You can start by changing his diet to a sensitive stomach type diet. If no improvement, have him examined by a veterinarian to start therapy if needed based on findings. Good luck!
