1, obesity
Most dogs snore because they are overweight and obese. Because of too much fat, their upper respiratory tract will narrow. When air passes through the narrowed respiratory tract, the surrounding mucosa will produce sound due to vibration.
To humans, dogs are snoring. Obese dogs are not only prone to accumulate fat in the upper respiratory tract, but may even be oppressed by excessive neck fat, which eventually leads to snoring.
2. heredity
Some dogs have a relatively long soft palate due to physical problems. Moreover, this long soft palate will block the dog's respiratory tract. When the dog breathes, the air will be blocked here and then make a sound. Of course, there is another situation, that is, dogs are born with "nasal stenosis".
This happens mostly to dogs with short noses. In addition, it is also common in Schnauzer, Chihuahua, Golden Retriever and Labrador.
3. Air pollution
Dogs snore when their noses are stimulated. If the owner smokes, the dog's nasal mucosa will be stimulated, and the secreted nasal mucus will block the dog's nasal cavity, leading to snoring. If the dog has allergic problems, rhinitis can also cause the dog to snore when it is allergic.
