Emergency Guide: What to Do If Your Dog Is Vomiting Blo

When vomiting undigested food, it may indicate that there could be an issue with the esophagus; if the vomit contains partially digested matter, the problem might be located in the stomach. The presence of a small amount of blood in the vomit raises concerns for conditions such as gastric ulcers, chronic gastritis, or gastric tumors. If the vomit is laced with large blood clots or a coffeecolored substance, it often suggests severe damage to the gastric mucosa, possibly pointing to severe gastritis, gastrointestinal bleeding, perforation, or a severe infectious disease. A vomiting substance with white foam and an acidic taste signifies a problem within the stomach. A vomit that is yellowgreen and slightly alkaline is indicative of small intestinal fluid, suggesting an issue within the small intestine. The presence of fecal matter in the vomit primarily points to problems in the distal small intestine or the large intestine. If the vomit is filled with a large number of foreign objects and accompanied by loss of appetite and unusual eating habits, it may indicate nutrient deficiencies or intestinal parasites.

If vomiting precedes the symptoms, it may suggest a gastric issue; conversely, if diarrhea comes first, the problem is likely in the intestines. In cases of canine distemper, affected dogs typically experience vomiting first, followed by diarrhea, with the feces containing blood and bubbles. With enteritis caused by parvovirus, dogs may first exhibit diarrhea, then vomiting, with the feces appearing like tomato juice, having a strong odor, and the dog losing its appetite, even with minimal water intake leading to vomiting. In cases of coronavirus infection, vomiting often occurs early and persists for several days before subsiding as diarrhea sets in. Canine hepatitis may also present with vomiting, but the dogs show an increased thirst, sometimes even drinking excessively with their front paws submerged in water, and the vomit often contains blood. Canine infectious tracheobronchitis may occasionally cause vomiting, but the more pronounced symptom is difficulty breathing. Puppies infected with canine herpesvirus may also vomit, usually after nursing, often expelling curdled milk. Paratuberculosis in dogs can cause severe vomiting, similar to acute gastroenteritis.
