Why Do Dogs Sneeze?

Dogs are playful, energetic, and curious creatures that often display a wide range of behaviors that can be both endearing and puzzling to their owners. One such behavior is sneezing. While sneezing in humans is often a sign of illness or allergies, in dogs, sneezing can have many different causes, ranging from harmless and normal to potentially serious.

As a pet owner, it’s important to understand why dogs sneeze, what may be causing your dog to sneeze, and when to seek veterinary care. In this article, we will explore the various reasons why do dogs sneeze and what you should do if your furry friend is sneezing excessively.

Why Is My Dog Sneezing? Main Reasons

When it comes to sneezing in dogs, it can be caused by a variety of factors. Sneezing is a reflex action that helps clear the nasal passages of irritants or foreign objects. While it is normal for dogs to sneeze occasionally, excessive or persistent sneezing can be a sign of an underlying health issue. Here are some possible reasons why your dog may be sneezing:

  • Allergies: Just like humans, dogs can develop allergies to a variety of environmental allergens such as pollen, dust, and mold. Allergies may cause your dog to sneeze, itch, and experience skin irritation or respiratory issues.
  • Infections: Respiratory infections such as kennel cough, canine influenza, or a sinus infection can cause sneezing in dogs. Dogs with respiratory infections may also show signs of coughing, nasal discharge, and lethargy.
  • Irritants: Exposure to irritants like perfumes, smoke, or cleaning products can irritate a dog’s nasal passages, leading to sneezing. Dogs may also inhale foreign objects, such as grass seeds or small pieces of food, which can cause sneezing and other respiratory symptoms.
  • Dental issues: Dogs with dental problems or infections may develop sneezing as a symptom. Tooth abscesses or infections can lead to nasal discharge, which in turn can cause sneezing.
  • Reverse sneezing: Reverse sneezing is a common respiratory issue in dogs that can cause sudden episodes of repeated, forceful inhalations that sound like snorting or honking. While it can be alarming to witness, reverse sneezing is usually not harmful and can be resolved by gently massaging your dog’s throat or covering their nostrils for a few seconds.
  • Nasal mites: Nasal mites are tiny parasitic insects that can live in a dog’s nasal passages and cause sneezing, coughing, and nasal discharge. They are more common in puppies and dogs who live in crowded or unsanitary conditions.
  • Tumors: Although it is less common, sneezing in dogs can sometimes be a sign of a nasal tumor. Other symptoms may include bleeding from the nose, facial swelling, and difficulty breathing.
  • Anatomic abnormalities: Some dogs may have anatomic abnormalities in their nasal passages or sinuses that make them more prone to sneezing or respiratory issues. Examples may include a deviated septum, narrow nostrils, or elongated soft palate.
  • Other factors: In some cases, sneezing may be a normal behavior in dogs, especially when they are excited or playing. However, if your dog is sneezing excessively or showing other signs of illness, it’s important to seek veterinary care to determine the underlying cause of the issue.

If your dog is sneezing excessively or showing other signs of illness, it’s important to take them to the veterinarian for a proper diagnosis and treatment plan. Your veterinarian can perform a physical exam, evaluate your dog’s symptoms, and recommend appropriate treatment. In some cases, diagnostic tests such as blood work, X-rays, or a nasal endoscopy may be needed to determine the underlying cause of your dog’s sneezing. With proper care and treatment, most dogs with sneezing issues can recover and enjoy good health once again.

Why Do Dogs Sneeze When They Play?

For a number of reasons, dogs may sneeze when they play, but in many situations, it is a typical habit linked to their joy and enthusiasm. Sneezing when playing may be a means for dogs to communicate with one another or with their owners. It can also be a way for them to let out stress and release stored up energy.

The anatomy of dogs is another factor that might cause them to sneeze while playing. Dogs may breathe in more dust, grass, or other particles when playing, which might irritate their nasal passages and make them sneeze. In a similar vein, dogs who are exposed to intense aromas or odors during play, such as the smell of other dogs or food, may sneeze.

Due to underlying medical conditions or allergies, some dogs may be more prone to sneeze during play than others. It’s crucial to visit a veterinarian if your dog is sneezing excessively or exhibiting other symptoms of sickness, such as coughing, wheezing, or nasal discharge, in order to identify the underlying reason and create an effective treatment plan.

Sneezing when playing is typically nothing to worry about and just an indication that your dog is having a good time. To make sure that your dog is healthy and happy, it’s always a good idea to seek veterinarian treatment if you detect any changes in their behavior or health.

When Dog Sneezing Is a Sign of Health Problems?

While sneezing in dogs can be a normal behavior, there are times when it may be a sign of underlying health problems. Some signs that your dog’s sneezing may be a cause for concern include:

  • Excessive sneezing: If your dog is sneezing more frequently than usual or having prolonged sneezing episodes, it could be a sign of an underlying health issue.
  • Nasal discharge: If your dog’s sneezing is accompanied by nasal discharge, it could be a sign of a respiratory infection or other health issue.
  • Changes in behavior: If your dog’s sneezing is accompanied by other changes in behavior, such as lethargy, loss of appetite, or difficulty breathing, it could be a sign of a more serious health issue.
  • Blood or mucus in the sneeze: If your dog’s sneeze contains blood or mucus, it could be a sign of an injury or infection in the nasal passages.

Allergies, respiratory infections, foreign items in the nasal passages, dental difficulties, nasal tumors, and anatomical anomalies are a few of the medical conditions that might make dogs sneeze. It’s crucial to speak with a veterinarian to identify the underlying reason of your dog’s sneeze and create an effective treatment plan if you’re worried about it or see any of the symptoms mentioned above.

Thus, even while sneezing can be a typical activity in dogs, it’s crucial to be alert to any changes in your dog’s sneezing patterns or behavior and to seek veterinarian treatment if you have any worries. Most dogs may overcome sneezing-related health problems and resume excellent health and a high standard of living with the right care and treatment.


In conclusion, while now you know why do dogs sneeze and that it can be normal, it can also be a sign of underlying health problems. If you notice excessive sneezing, nasal discharge, changes in behavior, or blood/mucus in the sneeze, consult with a veterinarian. With proper care, most dogs can recover and enjoy good health. Keep an eye on your dog’s health and behavior and seek veterinary care if you have any concerns.
