Dog owners might wonder about the reasons behind their dog’s frequent sneezing. Occasional sneezes are normal, but if a dog sneezes excessively, it could indicate a health issue. The following information delves into why dogs sneeze and when it might be a sign of something more serious.
Anatomy of a Dog Sneeze
Despite the distinct appearance of dog noses compared to human noses, their structure is quite similar. According to PetCoach, the pharynx, situated at the back of the throat, connects the nasal and digestive passages. When irritants invade the nose or pharynx, the body’s natural reaction is to force air out through the nose and mouth, resulting in a sneeze.
Common Causes of Dog Sneezing
There are various reasons why dogs might sneeze, ranging from simple dust particles to more complex viral infections. While sneezing is typically harmless, it can occasionally point to underlying health concerns. Here are the most prevalent causes of sneezing in dogs:
- Irritants and Foreign Objects: Dust, pollen, and other small particles can get trapped in a dog’s nose or pharynx, causing irritation. Dogs’ noses can also be sensitive to perfumes, cigarette smoke, and cleaning products.
- Allergies: Dogs can be affected by seasonal allergies to different types of pollen. Symptoms often include itching, scratching, watery eyes or nasal discharge, and sometimes intermittent sneezing.
- Colds and Viruses: Dogs can catch the common cold and viral infections that lead to sneezing. A dog with a cold or virus may show other signs of illness, such as nasal discharge, coughing, watery eyes, lethargy, fever, or a reduced appetite.
- Infections: Bacterial and fungal infections in a dog’s sinuses or nasal cavity can cause sneezing. Tooth infections that extend into the nasal cavity are also a possibility. Signs of infection usually include thick or bloody discharge, swelling around the nose, and potentially a loss of appetite.
- Tumors: Although rare, sneezing can be an indicator of a nasal tumor, especially in dogs over eight years old, as noted by PetCoach. Sneezing may start sporadically but increase as the tumor grows, often accompanied by bloody discharge from one nostril.
- Excitement: Sneezing can occur when dogs are excited or happy, possibly due to nose wrinkling that triggers the sneeze reflex. A dog sneezing upon greeting its owner is usually a sign of joy.
When to Consult a Veterinarian
While infrequent sneezing without other illness symptoms is generally not a concern, persistent sneezing warrants attention. Allergies that cause sneezing and additional issues like itching or skin irritation should be discussed with a veterinarian. If sneezing is accompanied by thick discharge, blood, swelling, fever, appetite loss, or lethargy, it is crucial to seek veterinary care immediately.
Regularly monitor for other symptoms if a dog sneezes often. While it may not be a serious concern, the cause of the sneezing should be investigated.
