Vet-Approved: Why Dogs Sneeze and 7 Natural Ways to Support Nasal Comfort

Have you noticed your dog sneezing more than usual?

Before calling the vet, let’s take a closer look. In many cases, sneezing is completely normal. Dogs sneeze when their nasal passages need clearing or when something irritates their nose.

While sneezing is usually harmless, frequent or excessive sneezing in dogs can sometimes indicate an underlying issue. In this article, we’ll explore common causes, simple ways to support your dog’s comfort at home, and when to consult a veterinarian.

What Exactly Does It Mean When a Dog Sneezes?

Sneezing is a dog's natural way of clearing irritants from the upper airway, which includes the nose, nasal passages, throat, and windpipe. While sneezing is a normal reflex, it can sometimes signal an underlying health issue. 

Notably, sneezing is typically characterized by a forceful exhalation.

How about reverse sneezing in dogs?

As the name suggests, "reverse sneezing" occurs when a dog rapidly inhales air through the nose, producing a series of forceful, sudden inspiratory sounds.

Just like regular sneezing, reverse sneezing is a normal reflex in dogs. It can be triggered by various factors, including excitement, eating or drinking too quickly, or excessive leash pulling.

7 Natural Ways to Support Your Dog’s Nasal Comfort

For a dog that is otherwise well, these simple steps can support nasal comfort. If sneezing is frequent, comes with discharge or blood, or your dog seems unwell, see your vet first.

#1. Maintain a clean environment.

It may seem simple, but keeping your home and surroundings clean helps protect your dog from excess dust and other airborne irritants. Regular cleaning, proper ventilation, and minimizing exposure to strong odors can significantly reduce potential triggers for sneezing.

A humidifier or vaporizer can help by adding moisture to the air and keeping their nasal passages moist. If you don’t have one, you can create a similar effect by bringing your dog into the bathroom, running a hot shower (without direct exposure to the water), and letting the steam build up for at least five minutes.

#2. Ask your vet about a gentle saline flush.

A simple saline solution and a syringe can be used at home to flush your dog’s nasal passages. 

Start the saline flush by dissolving 1/4 to 1/2 teaspoon of salt in 1 cup warm water. Fill a syringe with the solution, then gently steady your dog’s head with a slight tilt forward. This helps prevent vomiting if the solution is too concentrated, as salty water is often used to induce vomiting in pets. 

Carefully insert the syringe into one nostril, aiming toward the back of the head. Gently inject the solution with minimal pressure, allowing it to flush out mucus or debris through the other nostril or mouth. Repeat for the other nostril to ensure a thorough cleanse. Ask your vet to show you how before trying it at home.

#3. Oatmeal adds beta-glucan fiber to the diet.

Oatmeal is rich in beta-glucan, a water-soluble fiber. Beta-glucan has been studied for its effects on the body after exercise, though research in dogs is limited.

Supporting your pet’s wellness with oatmeal is simple. Soak two teaspoons of plain oatmeal in cold water overnight, then mix it into their meals as a simple addition to their diet.

#4. A little local raw honey is a popular addition.

Some pet parents add a little local raw honey to their dog’s diet. The idea is that small amounts of local pollen may help the body get used to it, but research on honey and allergies is limited.

Recommended dose: Use 1/2 teaspoon for small breeds and 1 teaspoon for medium and large breeds. Avoid giving 1 teaspoon to small breeds, as it may be too much for them. Do not give honey to puppies, diabetic or overweight dogs without asking your vet.

#5. Turmeric is a common kitchen supplement.

Turmeric contains curcumin, an antioxidant that has been studied for its effects on the airways, mostly in lab research.

If your vet agrees, peel and grate a small piece of turmeric, then mix it thoroughly into their meals. Ensure it's well integrated, as large pieces may be too spicy for your pet.

The recommended dosage for powdered or freshly grated turmeric is 1/8 to 1/4 teaspoon per day for every 10 pounds of body weight, with a maximum of 1 tablespoon for large breeds.

#6. A diluted apple cider vinegar rinse helps keep the coat clean.

Allergens that cause your dog to sneeze can sometimes hide in their coat. A diluted apple cider vinegar spray is a simple way to keep your dog’s coat clean.

Mix equal parts apple cider vinegar and water in a spray bottle, then shake well before use. Avoid applying the mixture to your dog’s cuts, ears, eyes, or face to prevent irritation.

#7. Zumalka’s SINUPET supports clear sinuses and easy breathing.

Zumalka’s SINUPET is a homeopathic formula designed to help maintain clear airflow and comfortable breathing, and it promotes sinus and respiratory health in cats and dogs. BREATHE-EZ (CLEAR) is a homeopathic formula designed to help support respiratory health and comfort. Neither is a treatment for colds, flu, allergies or infections, so sneezing with discharge, nosebleeds or facial swelling should always be checked by your veterinarian.

For everyday wellness, Zumalka’s GENERAL DETOXIFICATION kit supports healthy kidney, liver, and lymphatic function and healthy, natural elimination as part of an everyday wellness routine.

What Causes Dogs to Sneeze?

Dogs sneeze for a variety of reasons. Here are some of the most common causes:

• Allergies: Triggered by food, environmental factors, or seasonal changes.
• Inhaled irritants: Strong odors from scented candles, cigarette smoke, vape emissions, and air fresheners can cause sneezing.
• Dental issues: Diseased gums, tooth infections, oral abscesses, polyps, or tumors may lead to sneezing.
• Brachycephalic airway syndrome: Breeds with short noses, such as Pugs and Shih Tzus, are more prone to sneezing due to their naturally restricted airways.
• Nasal mites: These parasites can cause itching and frequent sneezing.
• Foreign objects: Small items lodged in the nasal passages can trigger sneezing.
• Infections: Fungal or bacterial infections may lead to sneezing episodes.
• Cancer: Nasal and, in some cases, oral cancers can cause sneezing accompanied by other clinical signs such as nasal discharge, nosebleeds, facial deformities, pawing at the mouth, and bad breath.

Interestingly, some dogs sneeze as a way to communicate with other pets. This behavior, known as “play sneezing,” is common in puppies and serves as a friendly signal to initiate or encourage playtime.

When Should You Be Concerned About Your Dog’s Sneezing?

As mentioned earlier, some cases of canine sneezing may require veterinary attention. Be sure to contact your vet if you notice any of the following signs:

Your dog’s sneezing is accompanied by a bloody discharge.

If your dog’s sneezing is accompanied by blood, it may indicate a serious issue in the airways or nasal passages. Common causes include nasal tumors, cancers, or foreign objects lodged in the nose.

Your dog’s sneezing is accompanied by a chronic cough.

In addition to bacterial or fungal infections, this could indicate health issues such as respiratory parasites, canine influenza, or kennel cough. It's important to note that these conditions are often contagious to other pets in your household.

Your dog’s sneezing is accompanied by wheezing.

While this is often triggered by intense exercise or play, it can also indicate lung health issues or asthma. Be sure to monitor your dog for any signs that suggest a more serious condition.

Urgent Signs Your Dog Needs Veterinary Care

Certain signs indicate that your pet may need immediate veterinary attention. If you notice any of the following clinical signs, consult a veterinarian as soon as possible to ensure your pet’s health and well-being:

• Raspy or noisy breathing: Changes in your pet’s breathing may indicate an underlying issue.
• Changes in nasal discharge: A shift in color or consistency could signal an infection.
• Bloody nasal discharge: This may be a sign of a more serious condition requiring prompt attention.
• Increased sneezing or nasal discharge: A sudden or worsening pattern should not be ignored.
• Persistent clinical signs: If sneezing and nasal discharge last more than a few days, a vet visit is recommended.
• Additional concerning clinical signs: Lethargy, vomiting, or decreased appetite alongside sneezing may point to a more significant health issue.

Early intervention is key to ensuring your pet gets the best possible care. A pet homeopathy expert can also help with a general wellness routine.

How Do Vets Determine Why Your Dog Is Sneezing?

To determine the underlying cause of your dog’s sneezing, the first step is reviewing their health history to identify potential triggers. This is followed by a thorough examination, focusing on the nose, eyes, throat, and lungs to ensure a comprehensive assessment.

To determine the cause of your dog’s sneezing, your veterinarian may recommend diagnostic tests such as X-rays, scoping, swabs, blood tests, or biopsies. Some procedures may require anesthesia or sedation to keep your pet comfortable and safe. 

Based on the results, your vet will create a personalized treatment plan to address your dog’s specific needs.

How Is Dog Sneezing Treated Medically?

The best conventional treatment for your dog’s sneezing depends on its underlying cause. Your veterinarian may recommend various treatments to help manage clinical signs and promote recovery. Here are some of the most common options:

• Sedation or anesthesia may be needed to remove a foreign object.
• Antifungal or antibiotic medications may be prescribed to treat infections.
• Surgical removal may be necessary for abnormal growths or tumors.

Antihistamines, nasal decongestants, and other medications are often used to help manage your pet’s sneezing. However, the best treatment will depend on the root cause, so it’s important to work with your veterinarian to determine the most effective solution.
