Every dog owner who has had a dog for a long time knows that it will poop at any time. They might vomit, but they might not even notice because they keep going with their day as if nothing had happened.

However, this article discusses the common question “Why is my dog throwing up undigested foods”?

Acid Reflux

Many dogs have reflux, which means that bile and food that hasn’t been fully digested come up in the middle of the night.

Yellow bile in the dog’s vomit usually means that bile from the dog’s small intestine is coming back up into the stomach and making the vomit yellow. Dogs often vomit several hours after eating at night.

This makes digestion more difficult and allows stomach contents to reflux back up into the esophagus. This causes pain and makes them more likely to vomit, and it is a sign of reverse motility.

Viral Infections

Dogs, like humans, can catch a stomach sickness. The majority of these bugs will go away in 24 to 48 hours, but some may require medical attention. If your dog is vomiting, appears to be lethargic, or has a temperature.

So, call your veterinarian to find out if you need to bring your pet in for treatment.

Simple Digestive Upset

In this case, there’s a good chance the dog didn’t like the food because it made it sick. If the dog’s stomach turns upside down by eating too much table food, this can happen.

This is because canines eat anything they find outside. Also, when dogs move to a new meal too quickly, they eat it joyfully that which affects them. In most cases, these problems get solved in 24 to 48 hours.

Bowel Disease

One of the reasons your dog is throwing up undigested foods could be inflammatory bowel disease. Dogs with IBD may vomit instead of having diarrhea like people with IBS. As a result, depending on which parts of the gastrointestinal system are damaged, you may vomit or have diarrhea, or both.

Poisonous Food

if your dog vomits undigested foods, try to remember what your dog ate. Because they may have eaten something they shouldn’t have, they may be sick. Among the things your dog might have eaten are chocolate, onions, and garlic. So, figure out what your dog might have eaten, and then call your vet.

Stress and Anxiety

Stress or a tense stomach can cause a dog to vomit food undigested foods. Many dogs may be stressed out because of changes in their lives, loud noises, or a fear of being alone. There are many other reasons your dog could become unhealthy.

Only your veterinarian can be sure that your dog is healthy. Ensure you take your dog to a vet as soon as possible.

7. Blockage

The dog may not be able to empty its stomach because there is a blockage in the way. Food could get stuck in the stomach and not be able to get out. This could lead to vomiting because the food could be pushed up and down.

8. Too much activity after eating

Keep the food you give your dog away from them while they’re running with you or during a training class. If a dog drinks or eats too much water while it is moving, it may vomit. If this is the case, you’ll most likely find the undigested food in the vomit.

Gastric Hypomotility

You should also check your dog for gastric hypomotility if it continues to vomit undigested foods. If your dog is old, this may happen more often than in younger ones. It doesn’t link to the gastrointestinal tract, but it can affect it and the heart.


There are many things that cause pancreatitis in dogs, but the most common are eating much fat. Pancreatitis can be very painful for dogs. It can make dogs very sick, making them lose their appetite, vomit a lot, and have an acute fever.

The pancreatitis type that makes dogs vomit undigested foods is the chronic type.
