Blood in Dog Stool: A Comprehensive Guide for Dog Parents

Causes of Blood In Dog Stool

• Parvovirus: Parvovirus is a highly contagious viral infection in dogs, especially puppies. It attacks the gastrointestinal tract, leading to severe vomiting, diarrhea, and dehydration. The intestinal lining becomes damaged, causing bloody diarrhea, which is one of the hallmark symptoms of parvovirus infection.

• Ulcers: Ulcers in a dog's gastrointestinal tract can occur due to various reasons such as ingestion of foreign objects, certain medications, or bacterial infections like Helicobacter pylori. These ulcers can lead to bleeding in the stomach or intestines, resulting in blood in the stool.

• Hemorrhagic Gastroenteritis (HGE): HGE is a condition characterized by sudden onset vomiting and bloody diarrhea in dogs. The exact cause of HGE is unknown, but it's believed to be triggered by factors like stress, dietary changes, bacterial infections, or toxins. The bloody diarrhea seen in HGE is often profuse and may contain fresh blood or have a raspberry jelly-like appearance.

• Inflammatory Bowel Disease (IBD): IBD is a chronic condition in which the gastrointestinal tract becomes inflamed due to an abnormal immune response to dietary antigens or intestinal bacteria. This inflammation can lead to ulcers, erosion of the intestinal lining, and subsequent bleeding, resulting in blood in the stool. Based on the extent and location of inflammation, dogs with IBD may exhibit either melena (if the bleeding occurs higher up in the digestive tract) or hematochezia (if the bleeding occurs closer to the rectum, resulting in fresh, bright red blood in the stool).

• Pancreatitis: Pancreatitis is the inflammation of the pancreas and can occur in dogs due to various factors such as dietary indiscretion, obesity, or certain medications. When pancreatitis occurs, digestive enzymes are released prematurely, leading to inflammation and damage to surrounding tissues including the intestines. This damage can cause bloody stools.

• Colitis: Colitis refers to colon inflammation and can occur in dogs due to infections, dietary indiscretion, allergies, or autoimmune disorders. Inflammation of the colon lining can cause irritation and bleeding, resulting in blood in the stool. Symptoms of colitis include diarrhea with mucus or blood, straining to defecate, and increased frequency of bowel movements.

Clinical Diagnosis

• History Taking

• Physical Examination

• Diagnostic Tests: Depending on the clinical findings and suspected main cause, the veterinarian may recommend various diagnostic tests, including:
• Fecal Examination: A microscopic analysis of the dog's stool can reveal the presence of parasites, bacteria, or other pathogens contributing to the bloody stools.
• Blood Tests: Bloodwork may be performed to evaluate the dog's overall health, assess organ function, detect signs of inflammation or infection, and rule out systemic diseases.
• Imaging Studies: X-rays or ultrasound scans may be used to visualize the dog's gastrointestinal tract and to look for any abnormalities, such as foreign objects, masses, or signs of inflammation.
• Endoscopy or Colonoscopy: In some cases, an endoscopic examination or colonoscopy may be recommended to directly visualize the inside of the dog's digestive tract and obtain biopsies for further evaluation.

Is Blood in dog stool an emergency?

• Severe or Persistent Bleeding: If your dog is passing large amounts of blood or experiencing persistent bloody diarrhea, it's essential to seek veterinary care immediately.

• Accompanying Symptoms: Bloody stool accompanied by other concerning symptoms such as vomiting, lethargy, weakness, abdominal pain, loss of appetite, or collapse warrants immediate attention. These signs may indicate a more serious underlying condition or complications that require prompt evaluation and treatment.

• Minor Gastrointestinal Irritation: Sometimes, dogs may experience temporary irritation or inflammation in the gastrointestinal tract, leading to the presence of blood in the stool. This can be caused by dietary indiscretion, mild infections, or changes in the environment. In such cases, the bleeding may resolve on its own without causing further complications.

• Anal Gland Issues: Anal gland problems, such as impaction or infection, can cause bleeding from the rectum.

• Rectal Injury: Dogs can injure their rectum or anus due to trauma, such as straining during defecation, rough play, or accidental injury. Minor tears or abrasions may result in bleeding without causing significant discomfort or other symptoms.

• Parasitic Infections: Some intestinal parasites, such as hookworms or whipworms, can cause bloody diarrhea in dogs. While these infections can be concerning, dogs may continue to behave normally if the infestation is mild or if they have developed some immunity.

Treatment for bloody diarrhea in dogs

• Fluid Therapy: Essential for managing dehydration associated with bloody diarrhea, especially in severe cases. Intravenous or subcutaneous fluids may be administered to restore electrolyte balance and prevent complications.

• Medications: Depending on the cause, antibiotics, anti-inflammatory drugs, or anti-parasitic medications may be prescribed to target bacterial infections, inflammation, or parasites, respectively. Anti-diarrhea for dogs would depend on these drugs.

• Dietary Management: Switching to a bland diet or prescription gastrointestinal diet can soothe the digestive tract. Easily digestible foods like boiled chicken and rice or specialized commercial diets for sensitive stomachs may be recommended.

• Probiotics: Supplementing with probiotics or digestive enzymes helps restore the balance of beneficial bacteria in the gut and promote gastrointestinal health.

• At-home Care/ Environmental Management: Addressing stress or anxiety factors is essential. Providing a calm environment and addressing stressors can aid in recovery.

• Monitoring and Follow-Up: Closely monitoring your dog's progress and adherence to follow-up appointments are crucial. The treatment plan's adjustment may be necessary based on your dog's response.

• Surgical Intervention: In rare cases of structural abnormalities or obstructions, surgical intervention may be required to correct the issue and alleviate symptoms.
