Some dogs vomit a yellow liquid on a chronic basis. Most cases of this form of canine vomiting can be treated at home with a few simple changes in feeding habits.

Many dogs are prone to chronic stomach problems involving a clear yellow liquid vomit, which often occurs on a regular basis – daily in many dogs. Fortunately, this form of upset stomach in dogs is often solved very easily, with some basic changes in feeding frequency and pet care.

“It’s not uncommon to see a liquid yellow or light brown vomit in dogs. It’s typically clear, sometimes a bit frothy and dog owners usually see this type of vomit first thing in the morning, or shortly before a scheduled meal,” explained Dr. Michael Levine, DVM.

He continued, “Generally speaking, dogs vomit a yellow liquid when they have an empty stomach. The bile and stomach acids accumulate in the empty stomach and this upsets the stomach’s lining, resulting in inflammation and discomfort.”

A variation of this form of chronic vomiting occurs when the dog’s body produces an excess of bile and stomach acid. This can result in symptoms such as stomach upset and vomiting, even after the dog has eaten.

Pet owners can also see vomiting in their dog immediately after a meal. This occurs because the bile and gastric fluids irritated the stomach beforehand, and adding food to the equation is simply too much for the already-upset stomach to handle.

In some cases, canine stomach ulcers can form due to the chronic stomach irritation, resulting in even more discomfort and frequent emesis. Medications like Pepcid AC, Zantac and Tagemet (active ingredient famotidine, cimetidine) are often prescribed in these cases.

There are several solutions and treatments that can help a dog who experiences chronic vomiting and stomachache.

  • Feed more frequently. Instead of feeding one or two large meals per day, divide the dog’s daily food portion into three or four smaller meals. This will help keep the stomach fuller, longer, preventing the accumulation of bile and gastric fluids.
  • Give Pepcid AC. Pepcid or other similar medications like Zantac and Tagamet contain a drug (cimetedine, famotidine or ranitidine) that helps to control the production of bile and stomach acids, thereby reducing the volume of the fluids that are the source of the dog’s stomach problems. Your veterinarian can prescribe a dosage based on the dog’s weight. The typical dosage for Pepcid is .25 mgs per each pound of body weight, given every eight to 12 hours. Always consult a veterinarian before giving medications, particularly if the dog is already on another drug, as drug interactions can be deadly.
  • Give wet food or hydrated kibble. Providing wet dog food or hydrated kibble will help reduce the chances of stomach upset and vomiting in dogs. When dry, dehydrated kibble is fed, the food absorbs fluids and expands once it reaches the stomach. If the dog eats until full, the further expansion of the food in an already-upset stomach can lead to vomiting. Adding hot water to the kibble and allowing it to sit for about ten minutes will allow the bits of kibble to absorb the water and expand beforehand.
  • Keep your dog's meals stress-free. Feed your pet in a quiet, stress-free location. Dogs are instinctively protective of their food and stress and anxiety that can result from the presence of other pets or even humans during mealtime. This stress can worsen existing stomach problems, so feed your pet in a quiet, isolated area.
  • Limit activity following meals. Activity like running, playing or even taking a walk around the neighborhood can lead to stomach discomfort and upset. In a dog whose stomach was irritated by excess bile and stomach acids, this activity is even more likely to lead to vomiting. So limit activity for the two hours following a meal to limit the potential for vomiting.

In the event that the aforementioned remedies do not lead to an improvement in the dog’s symptoms, a visit to the veterinarian is in order. A vast array of canine health problems can lead to vomiting in dogs, including (but not limited to) tumors and masses and other growths, gastritis, food allergies, pancreatitis and intestinal obstructions.

Dr. Levine concluded, “Most cases involving a dog who is vomiting a yellow fluid can be solved with more frequent feedings, medication and a couple other measures. But in a few instances, an underlying problem is to blame. So if you don’t see improvement, additional investigation will be required.”

Great information - thank you. My dog has the exact symptoms you discribe. Vomiting the yellow bile first thing in the morning. I'm thinking we might be playing ball too late in the evening and it's getting his stomach juices running. I've tried giving him a small meal before bed but it doesn't seem to help much. What do you thik of pepto bismo for dogs?

Thank you so much, this is very helpful, my dog has exactly this problem, will start giving her little amounts of food more often, she is a basset hound and this will also help with her gorging herself on food at the same time. She's not too keen on the dried food she has so perhaps the more moist version will also help. Again thanks for your help as this was very worrying for me.

Nice to find an article that describes exactly the problem I have been having with my Westie for the past month. The vet did blood work and stool analysis and nothing abnormal showed up. He prescribed Ranitidine twice a day but nothing has helped. My dog vomits yellow liquid every morning and is fine afterewards. He is vey hungry, energetic with no behavoural changes. This week I have to take him to the hospital for a 'scope or barium swallow. Getting quite worried.

i changed my dog food 3 days ago and now he is throwing up the yellow stuff and pooping every where.. he started to look weak yesterday being the 2nd day so after coming home to our bath room covered in poop and throw up i took the new food away and gave him water only until later last night when i gave him wet food. he seem to be getting better. then this morning the throwing up started again and the pooping. my boyfriend took him to the vet and now they want ot keep him all day and run all these test on him.. from the sounds of it the new food just didnt sit right and his body is rejecting it causing him to get it out of his system. my boyfriend seems to think there is more to the story and wants him to stay...

Thank you for answering a mystery for me! My mini schnauzer has had this issue for a couple of years and the vet was clueless! She is healthy and happy (aside from being blind) otherwise but we felt terrible about the constant vomiting. She does the morning "yellow" and also the dry heaves before some meals. She also just vomits food frequently. I am hoping that switching her to 4 meals a day and getting her pepcid or something will eliminate the issue.

To the owner of the sick dog (Comment from July 7, 2010):

I'm sorry to hear your dog is unwell. It's a good thing that he's at the vet for testing; I would do the same if this was my dog. Particularly now, as Parvovirus outbreaks have been reported in many parts of the U.S. (diarrhea is a main symptom of parvo.) It could also be something much more serious, like an illness, disease, tainted food, salmonella, etc., so further testing is definitely prudent.

I would also perform a Google search for the name of your dog food and the term "Recall" to see if any recalls have been issued.

Generally speaking, if a dog hasn't started to recover within 24 hours, it's time for a vet visit. That's not to say he'll be back in top shape within 24 hours; it can take several days for complete recovery to occur. Particularly in the case of vomiting and diarrhea. Once the stomach is upset, it stays very sensitive for several days thereafter. It's made even worse by the stomach acids and bile that accumulate in an empty stomach. So you need to provide very small meals of bland food (rice and skinless chicken or hamburger meat with the oils blotted off with a paper towel) several times a day. When I say "very small meals," I mean 1 or 2 spoonfuls -- a bite or two -- to start; each meal can be a slight bit larger. It's best to wait 4-6 hours between each meal. If vomiting occurs, wait 2 hours until trying to feed again.

Normal food can be gradually re-introduced (mixed in with the bland food) after 2 days without vomiting and normal bowel movements. If the dog still cannot hold down meals, a vet visit will be necessary. Sometimes, medications are necessary to stop the self-perpetuating cycle of vomiting and diarrhea. (Once the food that triggered the stomach upset is gone, the dog vomits because he has an empty stomach; the dog has an empty stomach because he's vomiting -- it's a circular problem)

When introducing a new food, it's important to do it gradually, over the course of about 2 weeks (a bit longer for dogs who are known to have a sensitive stomach). You gradually add the new food, while gradually lessening the percentage of the old food in each meal. This is a vital step; otherwise, diarrhea and/or vomiting are apt to result.

I hope your dog is feeling better soon!

This artical was very helpful thank you to whomever put this out there for crazy worrying momies like myself. My baby is very important to me and I'd hate to take him to the vet and have him poked and proded for no reason. This is exactly what i needed to read to help my baby boy boxer feel better asap. Thank you again.

Thank you for this information. My dog is a 17 month old puggle and is very energetic and healthy, but this morning on our walk he was vomiting a yellow liquid. My mom has put him on a very strict feeding schedule with her dogs once a day when we eat dinner. >:( I already didnt like the idea, and now Biscuit (my dog!) will be on a better eating schedule!!!! thank you!

Great information - exactly what my dog is experiencing. Thank you!

I must say that this was much informative. Thank you very much. Wish I would have found this a few years back when the vet decided that they were going to cut into my little Sassy to only find that there was no underlying cause of her vomiting.

Thanks so much...this was great...I followed the suggestions and fixed my dogs problems...AMEN!

Yep, this sounds all too familiar! Thx so much for clearing this up. Makes sense because my dog produces bile only after a dry meal, or the next morning. She's okay when I mix her wet & dry with a little warm water. The days when she is out of the canned... Well, she may have to wait a couple days... Here comes the bile, mainly in the morning. Or on the weekend after turbo playtime! We may try waiting a little bit to go outside for a walk after mealtimes. Never thought of that one, thank you Mia!

informative-my Tinkerbell had an HGE (bloody vomit & diarhea) attack last week. I rushed her to vet and that was what was diagnosed and she spent day there on IVs etc. She has been doing great until this morning when she vomited yellow bile . She hadn't been fed yet. I think i started her back on kibble too soon-just a few kernels mixed in but not soaked in hot water . I eliminated the kibble and am feeding soft skinless baked chicken & cottage cheese. I will take to vet to discuss pepcid as she is still on antiobiotics.

This article was great! Very informative and helpful. My dog was vomiting clear yellow fluid but didn't seem lethargic or having other symptoms but I was still quite worried about him. I live in the boonies over 10 hrs away from a veterinarian office that its not feasible to travel especially if the forest service road is not plowed from the recent snow dump we're still having! Knowing that his symptoms is not life threatening was a relief and it also gives me peace of mind knowing what symptoms are more serious that driving out no matter what will have to be chanced!
Anyways, Binoo is actually my 9 yr old granddaughter's dog. She's had him for 2 years now and if anything should happen to him while she's with her mother would break her heart and mine. He's a fearless dog and a very good protector for the family even though he is only a terrier mix bred dog. The rascal even chased a 7 1/2 foot grizzly out of the yard in September of this year!! ...fearless but crazy little bugger and he's all ours! <3

It was a relief actually to find out how common the vomiting is! However my dog was actually having an allergy problem that was causing his stomach upset. He is on a hypo-allergenic diet and when he reacts to insect bites or certain pollens I can safely give him Benedryl and Pepcid.

Wow! I wish I had found this site before my $500 vet visit and to make my dog more comfortable earlier. Your suggestions/Pepcid ac dosage is right on the mark. I will be trying the more frequent feedings to reduce/hopefully eliminate the frothy/yellow bile.
