Dog Snoring: What Pet Owners Need to Know

If you’re one of those people who can only fall asleep with your dog in bed with you, then you’re probably already used to his snoring habits.

Chance are, your dog’s snoring is perfectly normal, but there are times when it can be a sign of an underlying medical condition. When is it time to take your dog to the vet? Why is he snoring? How can I help him sleep better? Here is everything you need to know about dog snoring.

What Causes Dog Snoring?

Anatomically speaking, snoring is a noise caused by the vibration of the soft tissues in your dog’s throat and mouth. The vibration arises when there is a disruption of the normal flow of air within your dog’s respiratory system. Here are a few of the causes behind dog snoring.


Dog snoring generally occurs when air movement is restricted in the nasal passageways or throat. As you’ll read below, there could be several factors that cause this to happen. Serious breathing conditions, such as hypothyroidism and sleep apnea, although rare, can also lead to snoring.

A Congestion

Dogs can catch colds and become congested just like humans do. Some of the symptoms of a cold include canine inflammation, irritation, runny noses, dog sneezing, wheezing, and snoring. There’s no cure for a cold, so if this is why your dog is snoring, you may just have to ride out the noise until his nostrils clear up and he’s feeling better.


Just like with humans, dogs can suffer from allergies. Dust, weed and tree pollen, dander, and smoke can irritate your dog’s respiratory system and make it more difficult for him to breathe. Allergies can affect your dog’s snoring because it can cause the tissues in his mouth to swell. Your dog may also be dealing with watery nasal discharge, which can cause heavy breathing or panting in dogs. If you start seeing signs of dog allergies, especially labored breathing, then you may want to speak with your vet about medications to alleviate the symptoms and potentially reduce his snoring. Food allergies in dogs can lead to more serious symptoms besides just snoring.

Aspergillosis, or Fungal Disease

When your dog happens to inhale mold spores, which are found in hay, grass, and compost piles, it can cause breathing difficulties. These spores enter the body through the lining of the nasal cavity, and lead to irritation and inflammation, which restricts a dog’s airways.

Cigarette Smoke and Snoring

If you smoke, it could be affecting your dog. Dogs that are exposed to frequent or constant cigarette smoke will be more prone to snoring. The chemicals and toxins found in tobacco can irritate your dog. They may also put him at a greater risk of developing allergies and serious canine respiratory infections. If your dog’s snoring is due to tobacco smoke, it’ll stop if you quit smoking or, at a minimum, stop in the house.

Dental Issues

A throat infection or growth in your dog’s mouth can also restrict your dog’s airways and cause snoring. These types of issues can become more serious and require a vet visit immediately.


If your dog has hypothyroidism, he may be suffering from other issues beyond snoring. These may include loss or thinning hair, a dull coat, excessive shedding, scaly skin, weight gain, reduced activity, and a lower ability to tolerate the cold. Your vet may prescribe medication or suggest medication or hormone supplements to fix the issue and reduce his snoring.


Any time your dog begins a new medication, make sure you talk with his vet about potential side effects. Some pain relievers may cause his throat to relax more than usual, which can lead to snoring. If the medication is the culprit, but essential to your dog’s health, then you’ll have to deal with the snoring. Again, talk with your vet to learn about your possible options for improving the snoring situation.


One of the most common causes of snoring in dogs is weight issues. When a dog is overweight or obese, fat can also collect in his throat, which blocks the airways and causes snoring. This can be extremely dangerous, because it can lead to the tracheal collapse in dogs. Of course, canine obesity can lead to many other issues besides snoring, so if you know that your dog is otherwise healthy, but has put on a few pounds, then work on reducing his weight. You can talk to your vet about a weight management plan for your dog and the appropriate weight for your dog’s breed.

Physical Obstruction

Sometimes a piece of debris can get stuck in your dog’s throat or nasal passage, making breathing more difficult. It might not be to the degree that he’s choking, but if he does have a physical obstruction, you might also notice your dog coughing a bit more than usual. If you know that your dog has been chewing on a tennis ball or rawhide, then call your vet immediately to remediate the situation.


If you have an English Bulldog, Shih Tzu, Boxer, or Pug, then you’re probably used to loud and heavy breathing. Breeds that are brachycephalic typically have a broad, short skull and a short snout. This means their airways are shorter and may have more trouble moving air in and out. While smaller breeds are more susceptible to snoring, that doesn’t mean you can ignore it, still check with your vet if you’re concerned because there still may be underlying breathing issues present. In case you are wondering though, here are a few of the breeds that are predisposed to snoring:

  • Pug – Pugs are prone to brachycephalic syndrome, which can make breathing difficult. So, while they are small, they can also be loud as well.
  • Bulldog – A bulldog’s flat face and shorter airways can also make breathing a challenge. You probably already know that snoring isn’t the only noise a bulldog will make; they can be quite noisy, and produce frequent, audible grunts and snorts too.
  • Black Russian Terrier – This breed can be pretty high maintenance. Their long hair needs to be regularly brushed and you’ll have to dry off his beard whenever he drinks, snoring comes with the territory of owning a black Russian terrier as well.
  • Pekingese – Pekingese can suffer from breathing issues, such as snoring. They may even suffer from acute respiratory attacks that can cause loss of consciousness if not monitored.
  • Clumber SpanielThese dogs tend to snore much more than the average breed. Clumber Spaniels are prone to a heart condition called canine dilated cardiomyopathy (DCM), which can eventually lead to breathing complications.
