My Dog is Throwing Up Yellow Bile
Dog Throwing Up Yellow Bile
Why is my dog throwing up yellow bile?
Few things are scarier for us pet parents than seeing our dogs vomiting yellow foam, or bile. It’s easy to panic, but take a deep breath! While it can sometimes signal something serious, often it’s just one of those random things that happen from time to time. The good news? There’s plenty you can do to help your pup feel better.
Let’s break down what’s going on here, figure out why it’s happening, and find out  what you can do — both in the moment and for the long term — to address the issue.
Remember: Even healthy dogs occasionally vomit for no reason. But if you do notice your dog vomiting often, or it turns into an ongoing problem, it’s always better to play it safe and check in with your vet. You know your furry friend best, and staying vigilant is key to keeping them happy and healthy.

What’s making my dog vomit yellow bile?
First off, what is bile? It’s the yellowish fluid that helps your dog digest their food. While it’s normal for it to stay in the stomach where it belongs, if your pup starts throwing it up, it could mean something’s up — and bile can be tough on their stomach and esophagus. If it’s not dealt with, this could lead to other problems.
So, why is it happening? Dogs can vomit for all kinds of reasons. If you’re seeing yellow bile in their vomit and this happens regularly — especially if it’s paired with other symptoms like diarrhea — it’s definitely time to call the vet.
Vomiting can be a symptom of a whole range of conditions, and getting to the root cause is the best way to make sure your dog feels better in no time.
 
You can’t protect your dog from everything, but giving them a healthy diet can always be a good start. Check out our “Fresh is Best” dog food review — you’ll be doing your furry friend a favor and helping with your own peace of mind too!

Symptoms of dogs throwing up bile
If your dog’s been throwing up yellow bile, it’s natural to worry — and honestly, your best bet is to give your vet a call. There are all sorts of possible reasons this could be happening, from toxins to intestinal blockages, and it can be tricky figuring out which ones are serious and which might not be.
That’s where your vet comes in — they can help get to the bottom of it. Plus, let’s face it — no matter the cause, your furry friend is probably feeling pretty uncomfortable and stressed. That alone makes it worth picking up the phone.
In the meantime, here’s a quick rundown of things you might notice before or after your pup vomits yellow bile.

Causes of vomiting with bile in dogs
When your dog’s throwing up bile, it could be due to a bunch of different reasons, so figuring it out often involves a process of elimination. That’s what your vet will most likely focus on — checking for possible causes one by one to narrow things down. It’s all about finding the root of the problem so your furry friend can get the care they need to feel better.
 
This is when the pancreas becomes inflamed, throwing off the enzymes that help your dog digest food. It’s a common culprit behind vomiting bile.
 
If your dog’s stomach is empty, they might end up throwing up yellow bile since there’s nothing else left to bring up.
 
Dogs have a habit of eating just about anything, so it’s quite common for them to ingest something that causes a blockage. When something gets stuck in their intestines and food can’t pass through, vomiting tends to follow.
 
Parasitic illnesses
Pesky parasites like Giardia, are notorious for settling in your pup’s intestines. They’re especially common in younger dogs and can lead to vomiting and other issues.
 
If your dog vomits bile off and on, it could be BVS. This happens when their stomach is empty for too long—there’s nothing to soak up the stomach acid and bile, so it leads to nausea and bile vomiting.
Diagnosis of vomiting with bile in dogs
Your first plan of action should be to consult a vet! The first thing to do if your dog is vomiting bile is to call your vet. It’s better to address the issue sooner rather than later because things could escalate — like your pup becoming dehydrated or losing a lot of weight.
Another smart move? Start keeping a vomiting log. This record can be really useful for the vet in figuring out what’s going on. Make notes like:
 
  • How often is your dog vomiting, and is it just bile, or is it sometimes mixed with undigested food?
  • When is it happening? Maybe your dog’s vomiting yellow bile mainly in the morning, for example? Or after eating? This information can help to lead the vet to a quicker diagnosis.
  • How is your dog’s general daily well-being — do they act as normal at times other than when the vomiting is occurring?
  • Did the vomiting start suddenly, or has it been going on for a while?
  • Is it happening constantly or sporadically?
 
Because sporadic vomiting can sometimes give normal results during tests, keeping a detailed vomiting record could really help your vet. It’s an invaluable tool for getting to the root of the issue.
The next steps your vet will take are likely to include these measures:
  • Conduct a thorough physical examination
  • Perform blood tests, including blood count, profile, and chemical analysis
  • Carry out a urinalysis. It’s also a good idea to bring a sample of the vomit for evaluation
  • Do a fecal smear to check for parasites
 
If these initial steps don’t provide clear answers, your vet might recommend further investigations like:
  • Radiograph or abdominal ultrasounds to spot any obstructions or foreign objects
  • Endoscopy, which allows them to examine the abdomen (your dog would need to be under general anesthesia for this)
  • Biopsies, as well as advanced imaging like MRIs, CT scans, or abdominal contrast studies if needed
  • Exploratory surgery in the most severe cases might be required to assess the stomach, liver, and other organs directly

Pets can be expensive, but it doesn’t have to cost the earth to look after your precious pooch. With the right Wag! Wellness Plan, you can get access to a yearly check-up, annual booster shots, 24/7 vet chat, and much more. 
Treating vomiting with bile in dogs
The treatment for your pup’s vomiting will ultimately depend on the cause of the problem. Here are some of the options your vet might suggest to help get your furry friend back on track:
For cases of acute vomiting, your vet might recommend a fasting approach. This doesn’t mean strictly stopping your dog eating for 24 hours, but limiting what they can have. They’ll then have you gradually reintroduce small portions of a bland diet, increasing the food amount very slowly to avoid triggering more vomiting.
Your vet might decide if your dog needs to be hospitalized during this treatment. This is because if water also needs to be withheld, they may need to keep a close eye on your dog and the fluids may need to be fed using an intravenous drip.
Intravenous therapy may also be needed to balance your pup’s electrolyte levels. 
If the vomiting is due to an obstruction, there’s a chance that an endoscopy might have successfully cleared the blockage. If not, surgery will be required to remove the obstructing item.
If an obstruction is causing the vomiting with bile, it’s possible that the endoscopy may have been able to free the blockage. If not, surgery will be performed to remove the obstruction.
For conditions like gastric motility disorders, your vet may prescribe medications to improve stomach function. In cases of bilious vomiting, something as simple as adding a small evening snack to your dog’s routine could help reduce stomach reflux and alleviate the vomiting.

The road to recovery for dogs vomiting yellow bile
Seeing your dog vomiting yellow bile can be alarming, but the good news is that most cases can be resolved quickly and effectively. Once your vet figures out what’s causing it and gets things under control, your pup should be on their way to a full recovery.
That said, if the diagnosis turns out to be something more serious that requires surgery, it might take a bit longer for them to get over it. In that case, your vet will guide you on how to help your dog get better, like limiting exercise and making sure they get plenty of rest.
And don’t forget — regular check-ups and staying in touch with your vet are key to keeping your furry friend healthy and thriving in the long run.

These systems are concerning and she needs to see a vet ASAP. The vet can check her over and may run some tests such as a blood test or abdominal scan. There are many possible causes for her symptoms including a gut obstruction, toxin ingestion, pancreatitis etc. The sooner we have her seen and start treatment, the better. Hopefully she is back to normal very shortly.

Hello- Thank you for your question. I’m sorry your pet isn’t feeling well. There are many different causes of vomiting and decreased appetite including G.I. obstruction, pancreatitis, toxin ingestion, or gastroenteritis, or cancerous causes. It would be best to take him to a veterinarian so they can examine him, run some diagnostics (x-rays and blood work) to assess the cause of his vomiting and provide IV fluids and anti-emetics to help him feel better. I hope he feels better soon.

My pet has the following symptoms:
Throwing Up Yellow, Lethargy, Trying To Throw Up But Nothing Comes Out
I'm worried about my dog. He was acting fine yesterday and this morning but out of no where threw up yellow liquid. He threw up once and then tried again but nothing came out. I took him on a walk afterwards and he pooped a regular looking poop. He also doesn't have a loss of appetite. He has also been very tired after our walk. Should I be worried and take him to the vet?

Hello- Thank you for your question. If it was a single episode of vomiting yellow bile and your pup is otherwise acting normally then I don’t think you need to head to the vet right away. If he has more episodes of vomiting, stops eating, or becomes lethargic or continues to retch with no production of vomit then at that point you need to have him seen. Occasionally dogs will have an episode of vomiting but when it continues vet care is needed. I hope his symptoms don’t continue.

My pet has the following symptoms:
Vomiting Bile, Extra Tired, No Appetite
She has thrown up bile and water that she drinks this afternoon and night and hasn’t eaten all day. Is a vet visit necessary or will the stomach settle on it’s own?

Thank you for your question. If she is not able to keep water down and is continuing to vomit, it would be best to have her seen by a veterinarian, yes. Small dogs can become dehydrated quickly, and your veterinarian will be able to examine her and see what the problem may be. I hope that all goes well for her.

Thank you for your question. She may have eaten something that did not agree with her, or she may have a parasite or infectious disease. You can try feeding her a bland diet mixture of boiled white chicken and boiled white rice for 2-3 days and see if that helps settle her stomach. If she continues to vomit or becomes lethargic, then she should see your veterinarian right away. I hope that all goes well for her!

My pet has the following symptoms:
Vomiting Bile
My golden doodle has been vomiting bile early in the mornings for a while now. She is off and on vomiting but other than that acts fine. We have tried switching her diet but nothing seems to work. She was on the Science Diet (Hills Nutrition) and we switched to Merrick. Any advice? I do not think she has swallowed any foreign bodies. She has before and acted nothing like this. She acts normal other than sometimes not being hungry.
