There’s nothing better than curling up with your dog after a long day. That is, until your dog starts snoring.
Snoring is caused when air vibrates as it travels in or out of the throat. Normally, air flows smoothly through the nose or mouth, into the throat, and down the windpipe. There are many things that can cause the air to vibrate.
Breed: Short-nosed breeds such as Bulldogs and Pugs are very likely to have snoring problems. Known as “brachycephalic”, these dogs often have an elongated soft palate. This means that the tissue at the back of the mouth is too long and can hang over the throat, causing snoring. While snoring on its own is not a health concern, dogs who snore due to an elongated soft palate are more likely to have difficulty breathing, and even go into respiratory distress.
Obesity: Excess weight can cause dogs to snore. Excess tissue in the throat makes snoring more likely, as does fat pushing on an already compromised airway.
Sinus infection: If the sinuses are stuffed up, air does not flow smoothly through them. This turbulent airflow vibrates as it reaches the throat, creating snoring.
Allergies: Like a sinus infection, allergies can cause inflammation and turbulent airflow that leads to dog snoring. This can be due to seasonal allergens or indoor irritants such as cigarette smoke.
When Is Dog Snoring a Problem?
Snoring is not necessarily a cause for concern. Many dogs who snore never have any serious breathing issues. For example, some dogs only snore when sleeping in a particular position.
However, snoring may be the first sign you notice of a more serious problem. A dog who only recently started snoring but who doesn’t have any of the identifiable causes listed above may have something blocking his nasal passages. This could be a foreign object, infection or even cancer. It is best to have your veterinarian do a thorough physical examination.
Dogs who snore regularly may be at risk for serious breathing problems. Brachycephalic dogs may have some or all of the characteristics of brachycephalic syndrome. Brachycephalic syndrome can lead to severe difficulty breathing, and even sudden death.
