1. Breed Characteristics

A common cause of snoring in dogs is due to the structure of their airways. Dogs with short noses, such as boxers, pugs, Boston terriers, English bulldogs, and Shih-Tzus, snore more.

These dog breeds can have several structural deformities that increase breathing difficulties and snoring, including:

  • They have narrow nostrils, which makes breathing difficult.
  • Narrowness in the trachea. When inhaling, the airways narrow and collapse.
  • The dog has an abnormal formation of laryngeal tissue in the throat that blocks airflow.

2. Sleeping Posture

For example, if your dog lies on his back, this position may cause the tongue to relax and fall back against the throat, partially blocking the airway.

Likewise, if your dog rests his neck on an object, it could put pressure on the neck and cause snoring.

3. Obesity

Obesity in dogs can also be a cause of your dog snoring.
Weight gain can cause excess tissue in your pet’s neck or throat.

These tissues restrict airflow, making your dog more likely to snore.

4. Allergies

Allergies can cause the tissues in your dog’s airways to swell and become inflamed. That swelling restricts the dog’s airflow and causes snoring.

5. Infections and diseases

Some common ailments are the reason why your dog snores.

Upper respiratory tract infections

You’ve probably noticed that your dog snores when he has a cold. Nasal congestion clogs the sinuses, making it difficult for air to flow freely through the nose.

Kennel cough

Canine infectious respiratory disease (CIRD) or kennel cough, is a highly contagious respiratory disease in dogs.

Kennel cough in a dog causes a dry, cough that sometimes sounds like your pup has something stuck in his throat.

This respiratory disease causes mild symptoms in some dogs but can progress to life-threatening pneumonia in others.
That’s why it’s essential to recognize the symptoms and seek veterinary treatment immediately.

You can vaccinate your pet against kennel cough to prevent your dog from contracting it.

Nasal mites or dermatosis is a skin condition that can affect a dog’s snout.


Fungal infections

6. Fluid buildup

The fluid buildup narrows the airways and affects normal airflow, causing snoring.

7. Tumors

Another cause of dog snoring is a tumor within the airways that obstructs airflow.
Likewise, nasal polyps are benign but can still be problematic because they interrupt normal breathing.

8. Hypothyroidism

Snoring may be because your dog is not producing enough thyroid hormone.
Hypothyroidism occurs when your dog does not secrete enough thyroid hormones, causing his metabolism to slow down. Low thyroid levels affect all of your dog’s organs. In 95% of cases, direct destruction of the thyroid gland causes hypothyroidism.

9. Dental Infection

The bacterial infection that causes a tooth abscess may be responsible for inflammation and swelling of nearby tissues.


If you are concerned about your dog snoring, talk to your veterinarian. He can help determine possible causes.
It’s not always easy to know if your furry friend’s snoring is something to worry about.
If the snoring is new, or your dog has a runny nose, is sneezing, or has a low energy level, this suggests a change worth investigating.
While snoring is usual in brachycephalic breeds, or the dog snores frequently, it could affect your dog’s ability to breathe comfortably.
Discussing with your veterinarian how the snoring started, your dog’s activities when the snoring occurs, when the snoring is better or worse, and any other abnormal signs will help you identify the cause.
