Common Causes of Dog Sneezing Blood
There are several possible reasons why your dog might be sneezing blood. Understanding these can help you respond appropriately:
- Foreign Object: A small stick, seed, or debris in the nasal cavity may scratch tissues and cause bleeding.
- Nasal Infection: Bacterial or fungal infections can irritate the sinuses and cause nosebleeds.
- Trauma: Rough play or accidental bumping into hard objects may injure the nose.
- Nasal Tumors: Growths inside the nose, more common in older dogs, can lead to recurrent nosebleeds.
- Blood Clotting Disorders: Conditions like hemophilia or ingestion of rat poison can cause spontaneous bleeding.
Symptoms to Watch Alongside Bloody Sneezing
Aside from bloody sneezing, monitor for these signs which may indicate a more serious condition:
- Facial swelling or nasal discharge
- Frequent sneezing without blood
- Loss of appetite or lethargy
- Eye discharge or pawing at the face
- Visible swelling on one side of the muzzle
- Unusual breathing sounds or snoring during sleep
What to Do If Your Dog Is Sneezing Blood
If you notice blood when your dog sneezes, follow these steps:
- Keep your dog calm and avoid excessive activity.
- Gently clean any visible blood around the nose.
- Use a cool compress on the snout to help minimize bleeding.
- Check for any visible objects in the nostrils but do not insert anything inside.
- Contact your vet if bleeding continues or reoccurs.

When to Go to the Vet
Visit your vet if:
- Bleeding lasts longer than a few minutes
- There’s blood in both nostrils
- Your dog seems disoriented or weak
- You suspect poisoning or ingestion of medication
How Vets Diagnose Bloody Sneezing
Your vet may conduct diagnostic procedures such as blood tests to check for clotting issues, nasal endoscopy to look for tumors or infections, and imaging like X-rays or CT scans to evaluate internal structures. In rare cases, biopsy may be required.
Home Remedies for Minor Nosebleeds
While veterinary evaluation is best, you can try home care if your dog seems otherwise healthy:
- Use a humidifier indoors to soothe dry nasal passages.
- Apply a cold compress to the snout for a few minutes.
- Avoid walks in dusty, pollen-heavy, or dry areas during flare-ups.
- Hydrate your dog well to support mucous membrane health.
Can You Prevent It?
While some causes are unpreventable, you can minimize risk by:
- Avoiding walks in areas with sharp grass or thorns
- Using non-toxic pest control methods around your home
- Monitoring playtime to prevent facial injuries
- Keeping up with regular vet checkups
