Is your dog vomiting yellow liquid? Vomiting in dogs is a common problem which will naturally result in worry for any dog guardian. When the vomit is yellow with a foam, mucus or watery consistency, it is particularly concerning. Dog vomiting can be linked to poisoning, indigestion, enteritis and more. Since vomiting is a symptom of many diseases, our veterinarian will need as much information as possible to achieve a diagnosis.
At AnimalWised, we ask why is my dog throwing up yellow? We look at the possible causes of this problem as well as what treatments may be administered.
Why is my dog throwing up yellow liquid?
When a dog throws up, it can have varying properties. For example, when a dog eats and vomits immediately afterwards, their vomit will be made up mainly of undigested food. If the dog has drunk a lot of water, it is understandable their vomit will have a greater liquid consistency. Generally, the reason a dog's vomit is yellow will be due to one of the following reasons:
- Ingestion of non-digestible substances
- Infectious disease
- Chronic disease
- Allergies or food intolerances
If your dog vomits watery yellow liquid, this is an indication your dog has already vomited several times. This yellow liquid is often identified as stomach bile, a fluid that secretes from the gallbladder to assist digestion within the stomach.
Bile may vary in color between yellow, green or brown. If your dog is vomiting yellow foam or yellow mucus, it is likely either bile or has some bile content. For more information, we recommend reading our article on why dogs vomit bile.

My dog is vomiting yellow and not eating
