Seeing your dog panting while also pooping blood is alarming and can indicate serious underlying health issues.
We outline the common causes of panting and pooping blood in dogs, what you can do, and when to seek veterinary help.
Dog Panting and Pooping Blood — Why It Happens
When a dog is panting and passing blood in its stool, this combination often points to acute gastrointestinal distress, such as hemorrhagic gastroenteritis (HGE), ulcers, poison ingestion, or trauma to the digestive tract. The panting occurs as a response to pain, shock, or stress, while the blood indicates inflammation or bleeding within the intestines or colon.
In some cases, severe dehydration or internal bleeding can also contribute to rapid breathing and weakness.
Because these symptoms can progress quickly and be life-threatening, it’s critical to seek immediate veterinary attention to identify the cause and begin treatment before the condition worsens.
Dog Panting and Pooping Blood: Common Causes
Gastrointestinal Injury or Trauma
Physical injury to the gastrointestinal tract is a common cause of bloody stool and panting. Dogs may swallow sharp objects, chew on bones, or ingest non-food items that can cut or irritate the stomach and intestines.
Symptoms include bright red blood in stool, signs of discomfort, restlessness, or panting due to pain. Immediate veterinary attention is needed to prevent complications like infection or internal bleeding.
Gastrointestinal Infections
Bacterial or viral infections can inflame the digestive tract, causing both diarrhea and blood in the stool. Infections like salmonella or parvovirus can be severe and sometimes life-threatening.
Other signs may include vomiting, lethargy, loss of appetite, and dehydration. Rapid treatment with fluids, medications, and sometimes hospitalization is essential to support recovery.

Parasites
Intestinal parasites, such as hookworms, roundworms, or giardia, can result in bloody stools and panting.
These parasites damage the intestinal lining and can lead to anemia and weakness if left untreated.
Dogs may also show signs of weight loss, a dull coat, vomiting, or visible worms in the stool.
Fecal testing and targeted anti-parasitic treatment from a veterinarian are crucial for resolution.
Inflammatory Bowel Disease (IBD)
Chronic inflammation of the intestines, known as IBD, can cause frequent diarrhea with blood and panting due to discomfort.
The inflammation can be triggered by immune system dysfunction, allergies, or chronic irritation.
Signs may include intermittent diarrhea, mucus in the stool, bloating, and reduced energy. Long-term management often includes dietary changes, medications, and ongoing veterinary supervision.
Anal Gland Problems
Impacted or infected anal glands can contribute to bloody stools and panting from pain. Dogs may strain while defecating or scoot their rear end along the floor.
Other signs include licking or biting at the anal area, swelling, or foul odor. Veterinary care is needed to express the glands properly and treat any infection or abscess.
Tumors or Polyps
Growths in the gastrointestinal tract, such as tumors or polyps, can lead to bleeding and discomfort, causing panting. Older dogs are particularly at risk.
Symptoms may include intermittent or chronic blood in the stool, weight loss, vomiting, and changes in appetite or behavior. Early diagnosis through imaging and biopsy increases the chances of successful treatment.
Coagulopathy or Clotting Disorders
Blood clotting disorders can make even minor intestinal irritation result in visible blood in the stool. Conditions like hemophilia or low platelet counts impair the dog’s ability to stop bleeding.
Other signs may include unexplained bruising, nosebleeds, or bleeding gums. Prompt veterinary testing and management are essential to prevent severe blood loss.
What to Do If Your Dog Is Panting and Pooping Blood
Keep your dog calm and confined to reduce stress and overexertion.
Ensure hydration by offering fresh water, and monitor for signs of dehydration such as dry gums, lethargy, or sunken eyes.
Avoid giving human medications unless specifically directed by a veterinarian, as many can be toxic to dogs.
Track the frequency and appearance of stools, noting any changes in color, consistency, or amount of blood.
Prepare to provide detailed information to your veterinarian, including diet, environment, and recent behaviors or exposures.
When to Call or Visit Your Vet
Immediate veterinary attention is required if your dog shows:
Continuous or worsening blood in stool
Severe panting or signs of pain
Vomiting, lethargy, or collapse
Signs of dehydration, including sunken eyes, dry gums, or weakness
Any systemic symptoms that suggest serious illness
Quick intervention can prevent complications like severe anemia, shock, or life-threatening infection.
