Dog Reverse Sneezing A Lot And Vomiting

Seeing your dog reverse sneeze is often alarming, but when it happens frequently and is paired with vomiting, it’s understandable to feel concerned. While reverse sneezing alone is usually harmless, the addition of vomiting can signal a few different underlying issues. This guide will help you understand what might be happening, what you can do at home, and when to call your veterinarian.

Quick Q&A: Common Questions

Question: Why is my dog reverse sneezing and then vomiting?

Answer: This combination often points to irritation or inflammation in the upper airway or throat. The reverse sneezing episode can trigger a gag reflex, leading to vomiting. Common causes include post-nasal drip from allergies, a foreign object stuck in the throat, or a condition like a collapsing trachea. In some cases, it can also be a sign of a more serious respiratory infection or gastrointestinal upset.

Understanding Reverse Sneezing and Vomiting

Reverse sneezing, medically known as paroxysmal respiration, is a sudden, forceful inhalation through the nose. It sounds like a snorting or honking noise and can be quite dramatic. Vomiting, on the other hand, is the active expulsion of stomach contents. When these two symptoms occur together, it is important to look at the sequence and context.

The Connection Between the Two

The link between reverse sneezing and vomiting often lies in the shared anatomy of the throat and upper airway. The pharynx is a crossroads for both breathing and swallowing. An episode of reverse sneezing can irritate this area, triggering the gag reflex and leading to vomiting. This is especially common if your dog has just eaten or has a lot of mucus in the back of the throat.

Potential Causes

Several conditions can cause a dog to reverse sneeze a lot and vomit. It is rarely one simple issue.

1. Upper Respiratory Irritation or Infection

Allergies, dust, smoke, or even a mild viral infection can cause post-nasal drip. This excess mucus drips down the back of the throat, causing irritation. The dog reverse sneezes to clear it, and the gagging can lead to vomiting.

2. Collapsing Trachea

This is a common condition in small breed dogs like Yorkies, Pomeranians, and Chihuahuas. The tracheal rings weaken and flatten during breathing. This causes a classic honking cough or reverse sneeze. If the episode is severe, it can cause gagging and vomiting.

3. Foreign Body or Mass

A small piece of grass, a seed, or a bit of food can get lodged in the nasal passage or throat. This triggers persistent reverse sneezing as the dog tries to dislodge it. The gagging and vomiting are a secondary response to the irritation.

4. Gastrointestinal Issues

Sometimes, the problem starts in the stomach. Acid reflux, nausea, or a mild gastroenteritis can cause a dog to gag and vomit. The gagging itself can look and sound very similar to reverse sneezing. In this case, the vomiting is the primary issue, and the reverse sneezing is a secondary symptom.

5. Brachycephalic Obstructive Airway Syndrome (BOAS)

Flat-faced breeds like Bulldogs, Pugs, and Boston Terriers are prone to BOAS. Their shortened airways make them more likely to reverse sneeze, gag, and vomit, especially after exercise or excitement.

Home Care and What to Watch For

If your dog is reverse sneezing a lot and vomiting, there are a few things you can do at home before seeing the vet.

  • Stay Calm: Your dog will pick up on your anxiety. Speak in a soothing voice.
  • Gently Massage the Throat: This can help relax the muscles and stop a reverse sneeze episode.
  • Cover the Nostrils Briefly: For a second or two, gently cover your dog's nostrils with your hand. This encourages them to swallow, which often stops the reverse sneeze.
  • Offer Water: Small sips of water can help clear the throat.

When to Worry

Call your veterinarian if you notice any of the following:

  • The episodes are happening multiple times a day.
  • Your dog is vomiting bile or blood.
  • Your dog is lethargic, has a fever, or is not eating.
  • You see blood or discharge from the nose.
  • Your dog is having difficulty breathing or is turning blue.
  • The vomiting is projectile or forceful.

What to Expect at the Vet

Your veterinarian will start with a thorough physical exam, paying close attention to the throat, nose, and chest.

  • History: They will ask about the frequency, duration, and triggers of the episodes.
  • Oral Exam: They will look for foreign objects, inflammation, or masses.
  • Imaging: X-rays of the chest and throat may be recommended to check for a collapsing trachea, pneumonia, or a foreign body.
  • Bloodwork: This can help rule out underlying infections or systemic illness.
  • Rhinoscopy: In persistent cases, a small camera may be used to look inside the nasal passages.

Prevention and Long-Term Management

Preventing these episodes depends on the underlying cause.

  • Manage Allergies: If allergies are the culprit, your vet may recommend antihistamines, a hypoallergenic diet, or allergy shots.
  • Use a Harness: For dogs prone to collapsing trachea, always use a harness instead of a collar to reduce pressure on the neck.
  • Control Weight: Excess weight can worsen both respiratory and gastrointestinal issues.
  • Avoid Irritants: Keep your home free of smoke, strong perfumes, and dust.
  • Slow Feeders: If your dog eats too fast, a slow feeder bowl can reduce the risk of gagging and vomiting.

Final Thoughts

While a dog reverse sneezing a lot and vomiting can be distressing to witness, many cases are manageable with the right care. The key is to pay attention to the pattern and severity. If the episodes are frequent or accompanied by other concerning signs, a veterinary visit is essential to rule out serious conditions. With proper diagnosis and management, your dog can return to happy, healthy breathing.
