Spotting blood in your dog’s stool is sure to be a cause for concern for pet parents. Today, our Fort Pierce team shares some of the causes, symptoms and treatment for bloody stool in dogs.
Why Does My Dog Have Blood In Their Stool?Noticing any type of blood in your dog's stool means you should call your veterinarian. Being able to describe and identify the type of blood in your dog's stool or vomit can help your veterinarian to determine the source of the blood, and will ultimately play a role in diagnosing your dog's condition.
- First it's important to determine whether what you see is actually blood, since ingesting red foods, Pepto-Bismol or red items such as lipstick or crayon can cause your dog's stool to appear as if it is blood-streaked. Take a really analytical look at your dog's stool, and be prepared to provide your vet with a detailed description and samples if requested.
Hematochezia in Dog's Stool
If the blood in your pet's stool is bright red, then it's Hematochezia. Typically, hematochezia originates from bleeding in the lower digestive tract, rectum or colon. Bleeding in this area will encourage your vet to investigate a particular set of conditions such as parvovirus, hemorrhagic gastroenteritis, cancer, viral and bacterial infections, parasites, digestion of something inappropriate, sudden change in pet's diet, rectal injury, or colitis.
Melena in Dog's Stool
- If the blood in your dog's stool is dark, sticky and tar-like then it's Melena, which is blood that has either been swallowed or digested. This condition points to issues in your pet's upper digestive tract, esophagus, stomach, or upper small intestine such as parasites, liver cancer. Other common causes of melena in stool include ulcers caused by medications, blood clotting disorders, post-surgery complications, tumors, polyps, or ingestion of blood (licking a bleeding wound, a mouth injury or a bloody nose).
Other Causes of Bloody Stool in Dogs
- Some other causes of bloody stool include intestinal blockages, trauma, bacterial infections, or fissures.
What To Do If You See Blood In Your Dog's Stool
Regardless of the type of blood you see in your dog's stool or vomit it is important to contact your vet, or your nearest emergency vet right away. Bloody diarrhea or vomiting can be a veterinary emergency requiring immediate care. Some causes of blood in stool or vomit are potentially fatal if left untreated, so it's always wise to err on the side of caution.

Diagnosing Bloody Stool In Dogs
Diagnosing the underlying cause of bloody stool in dogs can be challenging. If routine diagnostic procedures are unsuccessful, more invasive procedures may be needed to diagnose the issue. The diagnostic procedure may include the following:
A Detailed Medical History
The more detailed information you can provide to the vet, the better. Some of the valuable information in your dog’s medical history may include:
- Whether your dog has experienced intestinal blockages, physical obstructions, ulcers or tumors in the past
- Your pet's vaccination record (to rule out parvovirus)
- How severe symptoms have been.
- Has it become worse?
Physical Wellness & Sample Examination
- Examination of the stool sample to confirm if blood is present
- Palpitation of the abdomen to check for abdominal obstruction or pain
- Heart function to look for symptoms of blood loss or dehydration
- Skin test to find out if your dog is dehydrated
- Biochemical tests checking liver function and blood sugar
- Packed cell volume (hematocrit) to confirm whether hemorrhagic gastroenteritis could be the cause
Endoscopy & X-rays
- To search for intestinal blockages, ulcers, tumors, or physical obstructions
- Fecal exams help to detect parasites or microbiological organisms
Treating Blood In A Dog's Stool
Treatment for bloody stool in dogs will depend on the underlying cause and your pet's general physical health. With the right treatment, most dogs respond very well and recover quickly. Treatment may include:
- Medications for soothing intestines
- Electrolyte and fluid therapies in the case of hemorrhagic gastroenteritis
- Antibiotic therapy if an infection is at the root of the problem
- Surgical remedies for tumors, ulcers or physical obstructions
- Corticosteroid therapy in cases of severe blood loss causing hypovolemic shock
- Anthelmintics (antiparasitic drugs) to expel parasitic worms and other internal parasites
Helping Your Dog Feel Better
Once your pet’s underlying issue is undergoing treatment, the main priority is allowing your pet's inflamed intestines time to recuperate. Your vet will be sure to provide you with detailed instructions on looking after your dog as they recover which may include,
- No food or water for 24 hours to allow your pet's intestines to rest
- Following the rest period, feeding a prescription or bland diet for a week or so before gradually returning your dog to their normal diet
- Monitoring your dog for other symptoms or recurring symptoms. If the problem quickly returns a prescription hypoallergenic medical diet may be recommended for your pet
- Restoring intestinal microflora by introducing food supplements (such as probiotics and probiotics) to help prevent the issue from recurring
