Dogs often snore due to allergies, rhinitis, fungal disease, tumors, dental problems, obesity or physical anatomies. While a snoring dog may sometimes be a normal occurrence, it is best to consult with a veterinarian to determine the specific cause.
If the dog typically snores around the same time every year, it may be due to seasonal allergies. Another cause of allergies in dogs may be exposure to cigarette smoke or other pollutants.
Snoring may also be caused by fungal infections, such as aspergillosis. This is a fungal infection caused by mold is found in grass or hay, and may lead to worse health conditions, such as loss of appetite, when left untreated.
Bad teeth may cause abscesses that swell and penetrate nasal passages. Untreated abscesses may spread throughout a dog's body and lead to systemic infections.
Prevent snoring in dogs by ensuring that they remain in good health. An overweight dog is likely to snore. Obesity in dogs causes the trachea to open and close as they breathe, resulting in a snoring sound.
Some breeds, such as pugs, have a natural tendency to snore due to their nasal anatomy. This can sometimes be treated with a nasal correction surgery. If a veterinarian determines that a dog's snore is not caused by a health problem, try repositioning the animal when it begins to snore.
