Common Causes of Bloody Diarrhea in Dogs
Dietary Indiscretion
Dogs are notorious for their scavenging habits, often ingesting things that are not meant for canine consumption. Eating spoiled food, bones, or non-food items like plastic or rubber can lead to gastrointestinal upset and bloody diarrhea.
Parasites
Internal parasites such as roundworms, hookworms, and giardia can cause inflammation in the intestines, leading to bloody diarrhea. These parasites can be contracted through contaminated soil or feces.
Infections
Bacterial, viral, or protozoal infections can also cause bloody diarrhea in dogs. Common culprits include:
- Parvovirus: A highly contagious and potentially fatal viral infection, especially in puppies.
- Salmonella: A bacterial infection commonly associated with contaminated food or water.
- Clostridium: A type of bacteria that can cause severe intestinal inflammation.
- Coccidia: A parasitic infection that can lead to bloody diarrhea and other digestive issues.
Inflammatory Bowel Disease (IBD)
IBD is a chronic condition characterized by inflammation of the intestinal lining. While the exact cause is unknown, it can lead to chronic bloody diarrhea and other digestive symptoms.
Food Allergies and Sensitivities
Certain foods can trigger allergic reactions in dogs, leading to inflammation and bloody diarrhea. Common culprits include beef, chicken, dairy, and wheat.
Tumors
Tumors in the intestines or surrounding tissues can cause blood in the stool.
Stress
Stress can trigger gastrointestinal issues, including bloody diarrhea. This is especially common in dogs with underlying anxiety or behavioral problems.
Pancreatitis
Inflammation of the pancreas, known as pancreatitis, can lead to severe digestive problems, including bloody diarrhea.
Liver Disease
Liver disease can disrupt the normal functioning of the digestive system, contributing to bloody diarrhea.
Signs and Symptoms of Bloody Diarrhea in Dogs
Besides the presence of blood in the stool, other symptoms associated with bloody diarrhea include:
- Diarrhea: Frequent and loose bowel movements.
- Vomiting: May be present alongside diarrhea.
- Lethargy: Reduced energy levels and inactivity.

FAQ
What are the most common causes of bloody diarrhea in dogs?
Bloody diarrhea in dogs can be caused by a variety of factors, including infections, parasites, inflammatory bowel disease (IBD), food allergies, and even cancer. Some of the most common infectious culprits include bacterial infections like Salmonella and E. coli, as well as viral infections like parvovirus and coronavirus. Parasites like Giardia and Coccidia can also lead to bloody diarrhea.
In addition to these causes, dietary indiscretion (eating something they shouldn’t), stress, and medications can also contribute to bloody diarrhea. It’s crucial to note that any instance of bloody diarrhea in your dog should be taken seriously, as it can be a sign of a serious underlying health issue.
What are the symptoms of bloody diarrhea in dogs?
Bloody diarrhea, or hematochezia, is characterized by the presence of fresh blood in the stool. This blood can range in color from bright red to dark brown, and may be mixed with mucus or accompanied by other symptoms like vomiting, fever, lethargy, and abdominal pain. It’s important to pay attention to the consistency of the stool, as well, as it can indicate the severity of the underlying problem. For example, watery diarrhea might suggest a mild gastrointestinal upset, whereas thick, bloody diarrhea could point to a more serious condition.
It’s important to note that not all cases of bloody diarrhea are immediately cause for alarm. However, if your dog exhibits any signs of distress, such as lethargy or loss of appetite, it’s important to seek veterinary care as soon as possible.
When should I take my dog to the vet for bloody diarrhea?
Any instance of bloody diarrhea in your dog should be considered a potential medical emergency and prompt veterinary care. There are a few key signs that should send you running to the vet, including:
- Blood in the stool is accompanied by vomiting, fever, or lethargy.
- The dog is experiencing severe abdominal pain.
- The dog is dehydrated, as indicated by sunken eyes, dry gums, or loss of skin elasticity.
- The bloody diarrhea persists for more than 24 hours, despite home remedies.
What will the vet do to diagnose the cause of bloody diarrhea in my dog?
The first step in diagnosing the cause of bloody diarrhea in your dog is a thorough physical examination. The vet will ask you about your dog’s recent diet, any medications they are taking, and any potential exposure to toxins or other animals. They will also check your dog’s temperature, listen to their heart and lungs, and palpate their abdomen to assess for any tenderness or abnormalities.
Further diagnostic testing may be needed to confirm a diagnosis. This can include blood work to assess your dog’s overall health, fecal analysis to rule out parasitic infections, or imaging tests like X-rays or ultrasound to examine the digestive system for any structural abnormalities.
How is bloody diarrhea treated in dogs?
Treatment for bloody diarrhea in dogs depends on the underlying cause. In some cases, the diarrhea may resolve on its own with supportive care such as providing plenty of fresh water and withholding food for 12-24 hours. However, if the underlying cause is more serious, treatment may involve:
- Antibiotics: For bacterial infections, antibiotics are often prescribed to combat the infection.
- Anti-parasitic medications: If parasites are identified, anti-parasitic medications will be prescribed to eliminate the parasites.
- Anti-inflammatories: For inflammatory bowel disease, anti-inflammatory medications may be given to reduce inflammation and pain.
- Dietary changes: In some cases, dietary changes may be recommended to manage the diarrhea, such as switching to a bland diet or a hypoallergenic food.
