Why does my dog vomit yellow liquid and foam from an empty stomach?

This could be due to acid reflux. You can try an ant acid medication such as omeperazole to see if it helps. If you don’t see improvement in 1 to 2 weeks, you should follow up with your veterinarian for diagnostics including bloodwork and X-rays.

Thank you for using Petco Pet Education Center, formerly Petcoach! The material you are describing is most likely bile, which can happen if an animal is hungry. Abbey may be eating dinner too early and getting hungry before going to sleep for the night. I recommend trying to feed her dinner a little later than normal. The signs you are describing can be unrelated to hunger, especially if Abbey does not eat meals. Vomiting can be caused by intestinal inflammation, hormonal conditions such as Addison’s disease or low thyroid levels. I recommend changing Abbey’s mealtime (if she is fed meals) for a day or two to see if this helps resolve the issue. If not, she should be seen by her vet to rule out the conditions above.

Hello. Vomiting in the morning as you are describing could a few different things, but the most common would billious vomiting. This is when they are hungry and the stomach is empty, so they actually vomit due to acid build up. Try feeding her a small snack before bed, or moving her dinner later than 6pm, and see if the vomiting stops. If it does, great, if not then she may have some other medical condition and an abdominal ultrasound would be recommended. Good luck with Sara.

Dogs generally vomit bile when they have an empty stomach. I recommend feeding small meals several times daily to reduce the vomiting. Or you can give a treat or two just before bed and first thing in the morning. Generally this is nothing to be overly concerned about. If she continues to vomit, doesn't feel well or starts losing weight then please take her in for and exam and bloodwork. Then if there is a problem they can start treatment right away if they find a medical issue. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Emma.

Thank you for using Petco Pet Education Center, formerly Petcoach! Chronic vomiting in dogs is pretty concerning and can be caused by gastritis, ulcers, foreign body obstructions, pancreatitis, and intestinal parasites. Other internal issues, for example kidney or liver disease, can make dogs nauseous as well. Sometimes, dogs will vomit yellowish liquid if they re extremely hungry and anticipating their meal. You can try feeding Urban a little later at night to see if this helps (this only applies if he eats meals rather than picking throughout the day). I recommend having him seen by a vet to ensure that nothing serious is causing his issues, especially if you are planning a trip. I hope this helps and that all is well with Urban!

Thank you for using Petco Pet Education Center, formerly Petcoach! Onyx is such an adorable girl! Dogs can vomit due to many conditions from stress, to ingestion of a foreign body or toxin, eating too quickly, intestinal parasites, or viral infections. If Onyx is acting normally, you can continue to monitor her at home. I recommend holding off food and treats until tomorrow morning, and then giving her only about 1/2 of her normal portion. She should have access to small amounts of water to prevent her from drinking too quickly and causing herself to vomit. She should be seen by a vet as soon as possible if you notice that she doesn't have an appetite or energy, or begins having diarrhea. I hope this helps and that Onyx feels better soon!

[Vomiting](https://www.petcoach.co/dog/condition/vomiting-1/) in dogs has multiple causes and can sometimes be a symptom of a greater underlying condition. In the absence of additional symptoms (lethargy, [diarrhea](https://www.petcoach.co/dog/condition/diarrhea-1/), loss of appetite, abdominal pain), most cases of vomiting can be managed at home with a bland diet fed in small frequent amounts until symptoms resolve. Gradually transition over 5-7 days to the regular diet afterwards. If vomiting persists for 24 hours or more, or if new symptoms develop, a visit to your veterinarian is recommended. That said, what you have described may be a condition known as bilious vomiting syndrome. The exact cause is unknown and it can affect dogs of any breed or age. Too long of a time between meals is thought to contribute to the condition. [Bile](https://www.petcoach.co/article/diseases-of-the-gallbladder-bile-duct-in-dogs/), which is quite irritating, may enter the empty stomach and can cause vomiting. Pet parents report a foamy, yellow vomit late at night or early in the morning. Since Tickles has been [vomiting](https://www.petcoach.co/article/how-to-deal-with-chronic-vomiting-in-dogs) so frequently, an [exam with your veterinarian](https://www.petcoach.co/article/what-does-your-veterinarian-look-for-during-a-physical-exam) would be recommended to either confirm bilious vomiting syndrome or to diagnose and treat another cause. Blood work and abdominal x-rays may be suggested after the exam. A bland diet and antacids may be dispensed. Offering a small meal just before bedtime may help as well.
