Dog Vomiting Undigested Food At Night  

Some common causes of vomiting in dogs include:

  1. Intestinal parasites, e.g., roundworms
  2. Ingestion of foreign objects like rubber balls, bones, hair, stones, and stick, among other objects 
  3. Illnesses like cancer, diabetes, and stomach ulcers 
  4. Stress, anxiety, and extra excitement 
  5. Ingestion of poison like pesticides, rat poison, household drugs, and antifreeze
  6. Ingestion of table scraps, garbage, and fatty food 
  7. Motion sickness 
  8. Viral infections like parvovirus and distemper 

Some common causes of vomiting in dogs include:

  1. Over-excitement and anxiety 
  2. Eating too fast 
  3. Overeating 
  4. The dog’s breed – regurgitating is more common in Labradors, Irish Setters, German Shepherds, Retrievers, and Wire Fox Terriers. 
  5. Dilation in the esophagus, which means the food does not move to the stomach

Difference Between Vomiting and Regurgitating

Regurgitating is when your dog throws up undigested content like food and other contents like saliva and water. The content will come out in a cylindrical-like shape because the regurgitated food is usually in the oesophagus. Regurgitating happens effortlessly; no contraction of muscles and no prior warning of things coming up. 

Vomiting, on the other hand, will have a couple of signs, contraction of muscles, and the dog’s body will be tense. These include whining, pacing, drooling, and gurgling noises from its stomach. The dog’s stomach will tense, and the muscles will contract to expel the vomit. It could even be caused by a Virus or Infection 

Vomit comes from the upper small intestines or the stomach of the dog. It can contain either partially digested or undigested food. 

If the contents are from the small intestines, the vomit will be accompanied by bile, either green or yellow. Vomit from the stomach will, however, have a clear liquid. 

Dog Throwing Up Food From Night Before – Major Problems

As mentioned earlier, dogs will throw up now and then. As such, pet owners sometimes do not worry much about it. However, if you see the below, then there might be more to the vomit. 

  • Blood – bloody vomit is a sign of gastric ulcers. It can also be a sign that your dog has ingested a sharp object like bone. The vomit does not have to be bloody, and if it looks like coffee pellets, then this is a sign of dried blood.
  • Endless vomiting – if your dog vomits once in a while, it is probably fine. It will not hurt to have a vet take a look, but it is nothing serious, especially if the vomit is not bloody. However, if the vomiting is endless, take your dog to the vet for immediate attention.
  • If the dog is not only vomiting but is also showing other signs like sleeping more often, diarrhea, or lack of appetite, a visit to the vet is highly recommended. These could be signs of other underlying health conditions.  

If your dog is vomiting undigested food at night, there is a high chance that it is regurgitating. If the content is yellow or gree or comes with a clear liquid, then this is vomit. It could be from the dog’s stomach or small intestines.

There are many dog vomiting treatment available, but a visit to the vet might help you understand the underlying cause, especially if the vomiting is endless or too often.
