Dogs are known for their unique vocalizations, from barks and whines to growls and howls. However, some dog owners may be surprised to hear their dog snorting like a pig. Your dog snorting like a pig can be alarming and confusing for pet owners unfamiliar with the phenomenon.

While it may look and sound like the dog is having difficulty breathing, it is a reflexive action that helps clear the nasal passages of irritants or mucus. Since pulling on a leash is most common in dogs, investing in a no-pull -harness could be of excellent service to prevent reverse sneezing as it would remove the pressure from the neck to the chest.

By understanding the causes of reverse sneezing, pet owners can better identify when their dog may need medical attention and when it is simply a natural and harmless occurrence. With the help of research and advice from experts like Dr. Brian Collins, D.V.M., we have compiled reasons why your dog is snorting like a pig and what you can do about it.

So, Why Does My Dog Snort Like A Pig?

When dogs snort like a pig it is usually a reverse sneeze. Reverse sneezing occurs when a dog inhales air rapidly through their nose, causing their soft palate to vibrate and snort. Dogs of all sizes can experience reverse sneezing. However, it is most commonly seen in small breed dogs and short-nose breeds, such as pugs and bulldogs due to their shorter snouts and narrower airways.

Some common triggers of reverse sneezing include allergies, irritants such as dust or smoke, Excitement or anxiety, exercise or pulling on a leash, and eating or drinking too quickly.

While reverse sneezing can be alarming, it is generally not something to worry about. However, if your dog experiences frequent or prolonged episodes of reverse sneezing, it is essential to consult your veterinarian to rule out any underlying health issues.

In some cases, reverse sneezing may be a symptom of a more severe condition, such as nasal mites, foreign objects lodged in the nasal passages, or respiratory infections. By understanding the common triggers and how to handle reverse sneezing, you ensure your dog stays happy and healthy.

Understanding Canine Reverse Sneezing

Reverse sneezing, also known as Pharyngeal Gag Reflex or Paroxysmal Respiration is sudden, rapid, and repeated inhaling loudly through the nose and mouth. This results in a snorting sound that resembles a pig’s snort and can be alarming to pet owners.

Research shows that reverse sneezing occurs when the soft palate and throat muscles become irritated, causing the dog to inhale forcefully. It is a reflex action that can be triggered by various factors such as allergies, respiratory infections, excitement, and irritants such as dust, pollen, or perfumes.

Paroxysmal Respiration is more common in small breeds, such as Chihuahuas, Pugs, and Bulldogs, but can occur in any breed. It usually lasts a few seconds to a minute and poses no danger to the dog. However, if reverse sneezing persists for an extended period, it may indicate an underlying medical condition that requires veterinary attention.

A reverse sneeze is typical in dogs and is typically not a cause for concern. It is characterized by a rapid inhalation of air through the nose, often accompanied by snorting or honking sounds.

Common Causes of Reverse Sneezing in Dogs

Reverse sneezing, also known as pharyngeal gag reflex or paroxysmal respiration, is a common condition in dogs. It is characterized by a sudden, rapid inhalation of air through the nose, followed by a snorting or a whistling sound. While it can be alarming for pet owners, reverse sneezing is usually harmless and self-limiting. This section will discuss some common causes of reverse sneezing in dogs.

1. Allergies

Allergies are a common cause of reverse sneezing in dogs. Dogs can be allergic to environmental triggers like pollen, dust, mold, and cigarette smoke. When a dog inhales an allergen, it can cause irritation and inflammation of the nasal passages, leading to a reverse sneeze. Allergies can cause other symptoms, such as itching, scratching, and watery eyes.

2. Foreign Bodies

Foreign bodies, such as sticks, grass, seeds, or small toys, can become lodged in a dog’s nasal passages, causing irritation and triggering a reverse sneeze. In some cases, the foreign body may need to be removed by a veterinarian, especially if it is causing significant discomfort or obstruction.

3. Overexcitement

Overexcitement can also trigger a reverse sneeze in dogs. This is especially common in small and toy breeds, which tend to be more excitable. Overexcitement can cause a dog to hyperventilate, leading to a reverse sneeze.

4. Rapid Eating or Drinking

Dog gobbling on their food and water can cause excessive inhalation of air, which can irritate the nasal passages and trigger a reverse sneeze and burping, leading to severe conditions like bloating. Slow feeding or using a puzzle feeder can help prevent this.

5. Irritants to the nose, throat, or sinuses

Irritants such as smoke, perfumes, cleaning chemicals, or other strong odors can cause reverse sneezing in dogs. These irritants can irritate the nasal passages, throat, or sinuses and trigger a reverse sneeze. Avoiding exposure to these irritants can help prevent reverse sneezing.

6. Brachycephalic Dogs & Reverse Sneezing

Brachycephalic dogs, such as Pugs, Bulldogs, and Boston Terriers, are more prone to reverse sneezing due to their short snouts and elongated soft palates. These anatomical features can make it more difficult for them to breathe, especially during periods of excitement or exertion. Brachycephalic dogs may also be more likely to develop respiratory infections or other respiratory problems, which can increase the risk of reverse sneezing.

Other Reasons Your Dog May Snort Like A Pig

While reverse sneezing is the most common reason dogs snort like a pig, other reasons could be causing this behavior (also see our article on why dogs grunt). Here are some of them:

1. Brachycephalic Airway Syndrome

Dogs with short snouts, such as pugs, bulldogs, and boxers, are prone to a condition called Brachycephalic Airway Syndrome. This syndrome can cause breathing difficulties, snorting, and snoring, among other symptoms. If you have a brachycephalic breed, it’s important to monitor their breathing and seek veterinary care if you notice any issues.

2. Play Sneeze

Some dogs snort like a pig when they’re excited or playing. This is often referred to as a “play sneeze.” It’s a harmless behavior and nothing to worry about. If your dog only snorts when they’re playing, it’s likely just a quirk of their personality.

3. Laryngeal Paralysis

Laryngeal paralysis is a condition that affects the muscles that control the opening and closing of the larynx. Dogs with this condition may snort, cough, or have difficulty breathing. Laryngeal paralysis is more common in older dogs, and it’s essential to seek veterinary care if you suspect your dog may be suffering from this condition.

4. Kennel Cough, Respiratory Diseases, and Flu or Colds

Like humans, dogs can get colds, the flu, and respiratory infections. These conditions can cause snorting, coughing, and other symptoms. If your dog is coughing like they have a hairball or showing signs of a respiratory illness, it’s important to seek veterinary care to ensure they receive the proper treatment.

5. Collapsing Trachea

In some dogs, the trachea (windpipe) can weaken and collapse, causing snorting, coughing, and difficulty breathing. This is more common in small-breed dogs and can be managed with medication or surgery.

6. Nasal Mites, Nose Tumors, Allergies

Less commonly, snorting can be caused by nasal mites, nose tumors, or allergies. If your dog’s snorting is accompanied by other symptoms, such as nasal discharge or sneezing, it’s essential to seek veterinary care to determine the underlying cause. Research suggests that although dogs of all breeds, ages, and sexes are vulnerable to this condition, large breeds and dogs older than three years are more susceptible.

Symptoms of Canine Reverse Sneezing

Canine reverse sneezing is a common condition that affects dogs of all breeds and ages. It is characterized by a sudden, rapid inhalation of air through the nose, which produces a snorting or honking sound. The following are the symptoms of canine reverse sneezing:

Quick and loud inhalation of air through the nose;
Snorting or honking sound;
Inability to breathe normally during an episode;
Stiffening of the body;
Extension of the neck;
Bulging of the eyes; and
Blue or pale gums and tongue (in severe cases).

Canine reverse sneezing episodes typically last a few seconds to a minute and usually resolve independently. However, in some cases, they can be prolonged and require veterinary intervention.

Difference Between Reverse Sneezing and Normal Sneezing

Dogs sneeze for various reasons, including allergies, irritants, and infections. However, reverse sneezing is a unique phenomenon that can be mistaken for a typical sneeze. Here are the key differences between reverse sneezing and normal sneezing:

Reverse Sneezing

Reverse sneezing, also known as inspiratory paroxysmal respiration, is a common occurrence in dogs. It is characterized by a rapid and repeated inhalation through the nose, which sounds like a snort or a honk. Reverse sneezing can last a few seconds to several minutes and can be alarming to pet owners unfamiliar with it.

Reverse sneezing occurs when the soft palate at the back of the mouth becomes irritated or inflamed. Various factors can irritate, including allergies, infections, irritants, or excitement. Reverse sneezing is more common in small dogs and brachycephalic breeds with short snouts.

Normal Sneezing

Normal sneezing in dogs is similar to sneezing in humans. It is a reflex action that helps to expel irritants, allergens, or foreign objects from the nasal passages. Normal sneezing is characterized by a single, forceful expulsion of air through the nose and mouth.

Various factors, including allergies, irritants, infections, or foreign objects in the nasal passages, can cause normal sneezing. Unlike reverse sneezing, normal sneezing is not usually a cause for concern unless it is frequent or accompanied by other symptoms such as nasal discharge, coughing, or lethargy.

How Do I Get My Dog to Stop Reverse Sneezing?

Calm Your Dog Down

Reverse sneezing can be triggered by excitement or stress. If your dog is prone to reverse sneezing, keep your dog calm and relaxed. Avoid loud noises, sudden movements, and panicking, as dogs are good at sensing when we are stressed, which could trigger their anxiety. You can also try massaging their throat to help relax their muscles and ease the episode.

Cover One Nostrils & Close the Mouth

Covering your dog’s nostrils can help to stop a reverse sneezing episode. Close your dog’s mouth gently and close one nostril. This will force your dog to swallow and may help to stop the attack.

Massage Your Dog’s Throat

Massaging your dog’s throat can help alleviate the symptoms of reverse sneezing. Use your fingers to apply gentle pressure to the sides of your dog’s throat, just behind the jaw. This can help open their airway and reduce the severity of the episode.

Offer Water

Drinking water can help to soothe the dog’s throat and stop the reverse sneezing.

Try Antihistamines

If allergies cause your dog’s reverse sneezing, antihistamines may help to reduce the symptoms. Speak to your veterinarian about the best course of treatment for your dog.

Overall, reverse sneezing is a common occurrence in dogs that is usually harmless. If your dog experiences frequent episodes, try these tips to help them stop. If you are concerned about your dog’s health, speak to your veterinarian.

Veterinary Interventions

If the dog’s reverse sneezing is frequent or severe, a veterinarian may recommend one or more of the following interventions:

• Antihistamines: Antihistamines can help reduce inflammation in the dog’s nasal passages and decrease the frequency of reverse sneezing.
• Steroids: Steroids can be prescribed to reduce inflammation in the nasal passages and decrease the frequency of reverse sneezing.
• Surgery: In rare cases, surgery may be recommended to correct a structural abnormality in the dog’s nasal passages, causing reverse sneezing.

It is important to note that pet owners should consult a veterinarian before attempting to diagnose or treat their dog’s reverse sneezing. A veterinarian can help to determine the underlying cause of the reverse sneezing and recommend appropriate treatment options.

When to Seek Veterinary Help

You should seek veterinary help when the reverse sneezing becomes more frequent or accompanied by other symptoms. This includes:

Chronic Reverse Sneezing

If a dog is experiencing reverse sneezing regularly, it may indicate an underlying health issue. Allergies, infections, or anatomical abnormalities can cause chronic reverse sneezing. A veterinarian can help diagnose and treat the underlying cause of the reverse sneezing.

Physical Distress

If a dog appears to be in physical distress, like difficulty breathing, coughing, or gagging when sneezing, it is essential to get a vet involved. These symptoms may indicate a more serious underlying health issue, such as a respiratory infection or obstruction.

Behavioral Changes

When a dog’s reverse sneezing is accompanied by behavioral changes, such as lethargy or loss of appetite, it may be time to call a vet. A veterinarian can help diagnose and treat the underlying cause of the reverse sneezing, ensuring the dog remains healthy and happy.
