Why is My Dog Throwing up Yellow?

It’s hard to stay calm when your pet suddenly vomits. We know that usually throwing up doesn’t mean anything good. And while we can understand the reason for this condition when it’s us being nauseous, the dog can’t tell you what happened. Therefore, you need to figure out why your dog is throwing up.

Sometimes it is okay if the animal threw up. For example, it could eat too fast, of the food got digested poorly. Or maybe the dog ate something that wasn’t edible, and the body needs to get rid of that thing. But if your pet’s vomit is colored yellow, and there is foam in it, you should be concerned.

What are the Reasons for Yellow Vomit in Dogs?

The vomit has yellow color because it contains bile that is usually yellow. It’s a digestive fluid that is produced in the liver and stored in the gallbladder. Often it is an indicator of a gastrointestinal system illness. However, there are less serious reasons for that.

When did the dog eat?

When the stomach is empty, bile irritates the lining, and the dog feels nauseous. As a result, it throws up yellowish foamy liquid. If it happened after your pet didn’t eat for more than 12 hours, you have nothing to worry about. If you feed your pup twice a day and it throws up yellow often, consider splitting meals into smaller portions and feeding the dog more frequently. But if the vomiting doesn’t go away, see your vet. The animal is likely sick.

Is your pup eating grass?

If you see bits of grass in vomit, you have an answer to the question, why your dog is throwing up. Many owners think that it’s natural for dogs to eat grass and then vomit – this is the way for animals to clean their digestive system. Why would they need to clean it, who knows. But intuition suggests that it’s not quite normal for a healthy dog to eat grass to call vomiting.

Therefore, you should see a doctor in this case. And it will be useful if you bring a sample of your dog’s vomit. If the animal feels the need to “clean” its stomach somehow, it might suffer from some illness.

VET Answers: why is my dog throwing up yellow

Did you change its food recently?

You should change the food gradually, slowly introducing new kind to the dog. If you were feeding your pet with one type of kibble just yesterday, and today you feed it with another, the animal will most likely throw up yellow. 

Consider that even if the brand of kibble is the same, but the taste is different, you should replace food gradually. Even a slight difference in the formula can cause issues with the digestive system. So don’t rush the process.

Are there any other symptoms?

If your dog has no appetite, is lethargic and has diarrhea on top of that – rush to the vet. If the skin, gums, or eyes of your pet gained yellow hue – that the reason to take a trip to the doctor. Pretty much anything can be a cause, from stress and side effects from some meds to serious issues like allergies, worms, other parasites, or digestive system diseases. Also, foreign items in the stomach or intestines can cause yellow vomit – that’s way is necessary to track your dog. Then your dog needs emergency surgery.

Bottom Line

In general, if yellow vomiting is repetitive, and you can see that the dog is unwell – see your vet. It’s much better to detect the issue while it is still developing than fixing the disease that is already progressing.
