Blood in Dog’s Vomit

It is a condition in which body digest blood or bright red blood in dogs vomit is found sometimes, this condition is also known as hematemesis.

Possible Causes:

  • Clotting Issues ??” The dog could have coagulophaties, which causes bleeding into the dog’s GI tract.
  • Stomach Ulcers ??” As opposed to bright red blood in dog’s vomit, the vomit of a dog with a stomach ulcer would look like coffee grounds because the blood has started to be digested by the stomach acids.
  • Bleeding tumors ??” may be located in the upper GI including the esophagus and stomach.
  • Stomach Irritation ??” May be caused by the use of medications that irritate the stomach lining and cause bleeding
  • Foreign Body ??” Sharp objects can lacerate the esophagus or stomach causing bleeding.
  • Swallowed Blood – A dog can also vomit blood that has been swallowed from licking a wound or from coughed up blood.

Symptoms Owners Should Watch Out For:

  • Anorexia
  • Melena ??” Look out for black tarry stools, this is a sign of digested blood
  • Diarrhea
  • Fresh Blood in the Stool ??” Caused by bleeding in lower GI tract
  • Signs of abdominal pain or abdominal guarding in dogs
  • Pallor, Pale Looking Gums ??” Could be a sign of severe blood loss
  • Syncope, Clammy skin, weakness, hypovolemic shock

Owners should be watchful for bleeding in other parts of the dog’s body.

Diagnosis and Treatment

This is a very serious condition and dogs should be taken to the vet immediately. Diagnostic tests would involve:

  • Imaging studies ??” X-RAY and CT Scans may be prescribed. Endoscopy may also be used to determine the source of the bleed
  • Ultrasound
  • Blood Work (CBC)
  • Coagulation profile ??” a dog may have an issue with clotting
  • Urinalysis
  • Fecalysis ??” in case of Melena

Treatment:

  • Food restriction
  • Fluid therapy and electrolyte replacement
  • Blood transfusion when needed
  • Gastric coating agents and gastric blockers
  • Surgery may be necessary in some cases.

Ulcers in dogs are basically the lesions in the gastrointestinal tract which extend deep into the lining and mucosa way.
In some cases, dogs will not show any outward symptoms of the condition until it progresses into the final stages. At that point, sudden death can occur, when the ulcers perforate and the stomach contents are poured into the body.

Symptoms of Gastrointestinal Ulcers in Dogs

Vomiting ??” the vomit may or may not contain blood. When it does have blood, it will appear as coffee ground vomit. This is caused by bleeding into the stomach where the blood has been digested. These are different from gastric erosions as erosions are superficial and will only involve the mucus lining.

  • Melena ??” Black and thick tarry stools that have a foul smell. This is a result of digested blood passing through  the intestines
  • Abdominal pain
  • Pale gums
  • Weakness
  • Low body temperature
  • Collapse
  • Lethargy
  • Listlessness
  • Anorexia
  • Shock (Hypovolemic)

Cause and Treatment

There are many factors that can cause this condition in dogs, they include:

  • Metabolic Diseases
  • Stress ??” this can include major injury or surgery
  • Major Illnesses
  • Foreign objects in the stomach
  • Heavy Metal Poisoning (e.g. lead)
  • Gastroenteritis ??” an inflammation of the stomach and intestines
  • Bacteria ??” the bacteria Helicobacter Pylori or H. Pylori is pinpointed as one of the major causes of ulceration of the stomach lining.

The goal of treatment is to give the ulceration some time to heal. If it is caused by a foreign object, removal is necessary. Antibiotics may be given if H.Pylori is determined as the cause.

Treatments for the condition include

  • Antacids
  • Enteric coaters ??” coats the stomach protecting the ulcer from the stomach acids
  • Pain medication ??” only certain types and not those that cause thinning of the lining (e.g. aspirin, NSAIDs)
  • Surgery

Dog Gastric Ulcer

This can be a serious condition in dogs as it can lead to more serious problems like perforation.

  • The condition can be caused by bacteria or by the use of certain medications.
  • It is painful, but the location of the pain is also determined by the location of the ulcer.

Causes

There are two causes of gastric ulcers in dogs, they are:

1. H. Pylori Bacteria

  • These bacteria are considered to be the most common cause of gastric ulcer in dog.
  • It causes depletion in the mucus lining of the stomach.
  • It is important to point out that not every dog that has H. Pylori will develop ulcers in the stomach.

2. Long Term NSAID Use

  • Non-steroidal Anti-Inflammatory Drugs are pain medications that are usually prescribed to dogs.
  • These drugs are known to cause thinning of the mucus lining of the stomach.
  • This can be prevented by regulating their use, and by taking the said drugs together with food in order to minimize the effect on the mucosa.

Other causes include stress (e.g. Major Surgery).

Dog Gastric Ulcer Symptoms

Here are some of the symptoms that a dog with gastric ulcers may experience:

  • Abdominal pain
  • Diarrhea
  • Nausea and Vomiting
  • Coffee ground vomit – The dog’s vomit will have a characteristic of coffee grounds due to the presence of bleeding the stomach.
  • Melena ??” Black tarry stools, this is another consequence of bleeding in the stomach.

Treatment

  • Antibacterial Agent ??” This is administered to help fight the H.Pylori Bacteria.
  • Acid Pump Regulators ??” They can help decrease the acidity of the stomach.
  • Antacids ??” These are medications that coat the stomach and give the ulcer time to heal without being exposed to acids.
