2025 Vet Guide: Dog Nosebleeds – Causes, First Aid & When to See a Vet 🐶🩸

By Dr. Duncan Houston BVSc

Nosebleeds in dogs—also known as epistaxis—are never normal and may signal anything from a simple scrape to a more serious health concern. This guide explains causes, immediate steps, diagnostics, treatments, and prevention strategies. 🛡️

🔍 1. What Is Epistaxis?

Epistaxis is bleeding from the nostrils, nasal cavity, or nasopharynx. It can range from a light drip to heavy bleeding.

⚠️ 2. Common Causes

• Trauma: Blunt or penetrating injury—most frequent cause.
• Foreign bodies: Grass awns, sticks lodged in the nasal passages.
• Tumors: Nasal cancers or growths—especially in older dogs—often cause persistent bleeding.
• Dental abscesses: Tooth root infections can leak into the nasal passages.
• Infections: Bacterial, fungal, or viral rhinitis/sinusitis.
• Clotting disorders: Von Willebrand disease, thrombocytopenia, DIC—can cause spontaneous bleeding.
• Hypertension or systemic illness: High blood pressure, liver disease, and cancers.
• Vasculitis or immune-mediated issues: Often systemic, causing intermittent bleeding.

🏥 3. First Aid Steps

• Stay calm and keep your dog quiet—excitement raises blood pressure and bleeding.
• Apply an ice pack (wrapped in cloth) to the bridge of the nose to constrict vessels.
• Don’t insert cotton or shove tissues—they can worsen bleeding.
• If bleeding lasts over 5 minutes or is heavy, seek veterinary attention immediately.

🔍 4. When to See a Vet

• Heavy, persistent, or recurrent bleeding of any amount.
• Bilateral bleeding (both nostrils), indicating a possible systemic cause.
• Signs like lethargy, disorientation, facial swelling, or breathing difficulty.
• Animal may swallow blood—vomiting or black/tarry stools could follow.
• Underlying chronic conditions (e.g., hypertension, tumor risk, breed predisposition to bleeding disorders): Dobermans, Shepherds, Corgis, etc..

🧪 5. Veterinary Diagnosis

• Detailed history and physical, including oral and nasal exam.
• Blood work: CBC, biochemistry, clotting profiles.
• Blood pressure check for hypertension causes.
• Imaging—X-rays, CT, rhinoscopy to assess the nasal cavity.
• Cytology/culture for infections; biopsy for suspected tumors or vasculitis.

🩺 6. Treatment Options

• Trauma/foreign body: Remove object, treat wounds, possibly cauterize.
• Infection: Antibiotics or antifungals as indicated.
• Dental disease: Extraction or root canal if the abscess is caused.
• Clotting issues: Transfusion, vitamin K for rodenticide, and treat the underlying disorder.
• Tumor or mass: Surgery, radiation, chemotherapy, depending on type.
• Hypertension: Treat the underlying disease and control blood pressure.
• Immune/vasculitis: Immunosuppressive therapy as prescribed.

📝 7. Prognosis & Follow-Up

Outcomes depend on cause: trauma/foreign body—often good; tumors or systemic diseases—variable; clotting disorders—requires ongoing management.

🏡 8. Prevention & Monitoring

• Supervise your dog outdoors to prevent trauma.
• Stay current with dental check‑ups and cleanings.
• Annual health screenings, especially for blood pressure and coagulation in at-risk breeds.
• Promptly treat any facial wounds or suspected sinus infections.

📱 9. Tools for Pet Parents & Vets

• Ask A Vet: Immediate triage for nosebleeds, guidance on severity.
• Woopf: Track episodes, bleeding volume, diagnostics, vet follow‑ups.
• Purrz: Monitor recurring issues, triggers, medications, and blood pressure records.

📚 FAQs

Q: Is a small trickle of blood normal after a sneeze?

No. Any blood—even a small amount—is abnormal in dogs and warrants at least a vet check‑up.

Q: Can home remedies stop the bleeding?

While ice helps, home care doesn’t treat underlying causes. Veterinary diagnostics are essential.

Q: When can I wait vs go immediately?

Heavy or persistent bleeding, bilateral flow, lethargy, facial swelling, or swallowing blood = emergency. Single nostril, mild bleed, stable dog = we can talk to your vet within hours.

💬 Owner Insight
