Most weird breathing noises in dogs are harmless, caused by something as simple as a spasm in the throat or mild irritation in the nasal passages. But some sounds point to conditions that need veterinary attention, especially if they persist, worsen, or come with other symptoms. The type of sound your dog is making, when it happens, and how long it lasts can tell you a lot about what’s going on.
Reverse Sneezing: The Most Common Culprit
If your dog suddenly starts making rapid, loud snorting sounds through the nose while standing still with their neck extended, you’re almost certainly witnessing a reverse sneeze. It looks alarming the first time, but it’s a normal reflex triggered by irritation in the back of the throat or nasal passages. During an episode, the muscles around the throat and soft palate spasm, pulling air inward forcefully instead of pushing it out like a regular sneeze. The whole point of the reflex is to move mucus from the back of the nasal passages down into the throat where it can be swallowed.
Common triggers include dust, pollen, excitement, pulling on a leash, eating or drinking too fast, and strong smells. Nasal mites and viral infections can also set it off. Episodes typically last 15 to 30 seconds and stop on their own. You can sometimes shorten one by gently rubbing your dog’s throat or briefly covering their nostrils to encourage a swallow. If reverse sneezing happens only occasionally, it’s nothing to worry about. Frequent episodes, more than a few times a week, are worth mentioning to your vet since they could signal chronic nasal irritation or an underlying issue.
Flat-Faced Breeds and Chronic Noisy Breathing
Bulldogs, Pugs, French Bulldogs, Boston Terriers, and similar breeds with shortened skulls are prone to a set of structural airway problems that make noisy breathing a daily reality. These dogs often have narrowed nostrils, an oversized soft palate that partially blocks the airway, extra tissue in the nasal passages, and sometimes a windpipe that’s narrower than normal. The result is snoring, snorting, and gurgling sounds during normal activity, and louder, more labored breathing during exercise or hot weather.
Some degree of noise is expected in these breeds, but it exists on a spectrum. A dog that snores lightly while sleeping is different from one that struggles to breathe after a short walk or can’t cool down on a warm day. If your flat-faced dog’s breathing sounds have gotten noticeably louder or more strained over time, or if they gag, retch, or seem to tire quickly, that suggests the airway obstruction is significant enough to discuss with a veterinarian. Surgical options exist to widen the nostrils and trim the soft palate, which can meaningfully improve airflow and quality of life.
The “Goose Honk” Cough
A persistent, harsh, dry cough that sounds like a goose honking is the signature sign of tracheal collapse, a condition where the cartilage rings supporting the windpipe weaken and flatten. This is most common in toy and small breeds like Yorkshire Terriers, Pomeranians, and Toy Poodles, particularly in middle-aged and older dogs. The honking often gets worse with excitement, pulling against a collar, drinking water, or in hot, humid conditions.
Tracheal collapse ranges from mild to severe. In mild cases, switching from a collar to a harness, managing your dog’s weight, and avoiding triggers can keep symptoms under control. More severe cases may need medication to reduce coughing and inflammation, and in some situations a stent can be placed inside the trachea to hold it open.
Kennel Cough and Other Infections
If your dog recently spent time at a boarding facility, dog park, groomer, or anywhere with other dogs and then developed a forceful, hacking cough that sounds like something is stuck in their throat, kennel cough is a strong possibility. It’s caused by a mix of bacteria and viruses that infect the upper respiratory tract. Dogs often sound terrible but otherwise act fairly normal, eating and drinking without much trouble.
The worst of the coughing usually improves within the first five days, but the full illness can linger for 10 to 20 days. Most healthy adult dogs recover on their own. Puppies, senior dogs, and dogs with other health conditions are more likely to develop complications like pneumonia. If your dog develops a fever, becomes lethargic, stops eating, or starts coughing up colored mucus, that signals a more serious infection.
Laryngeal Paralysis in Older Dogs
If your older large-breed dog has developed progressively noisy, raspy breathing, especially during exercise or warm weather, laryngeal paralysis could be the cause. The larynx normally opens wide when a dog breathes in. When the nerves controlling it stop working properly, the opening doesn’t widen enough, and the dog is essentially trying to breathe through a narrow gap. Cornell University’s veterinary team compares it to breathing through a straw.
Labrador Retrievers are the most commonly affected breed, but it occurs in many large breeds. The condition tends to develop gradually. Early signs include a change in bark (it may sound hoarse or weak), noisy breathing that worsens with heat or exertion, and exercise intolerance. In advanced cases, dogs can overheat quickly because they can’t pant effectively. Surgery to permanently tie one side of the larynx open is the standard treatment for dogs with significant symptoms.
Something Stuck in the Nose
Sudden, violent sneezing that comes on out of nowhere, especially after your dog has been outside sniffing around grass, dirt, or sand, can mean something is lodged in a nostril. Grass awns, foxtails, small sticks, and seeds are common offenders. You may also notice nasal discharge from one side only, which is a strong clue. The dog will often paw at their face and may have noisy, snuffly breathing between sneezing fits.
Some foreign objects work themselves out with sneezing, but many don’t. Objects left in the nasal passages can cause infection and worsening discharge over days. If the sneezing persists for more than a few hours or you see thick or discolored discharge, your dog will likely need sedation so a vet can visualize and remove whatever is stuck.
Breathing Changes Linked to Heart Problems
Not all abnormal breathing sounds come from the airways. When the heart isn’t pumping efficiently, fluid can build up in or around the lungs, causing faster, shallower, or more effortful breathing. This is especially relevant for dogs already diagnosed with a heart murmur or heart disease, but it can also be the first noticeable sign.
A useful number to know: a healthy dog at rest or asleep typically breathes fewer than 32 to 35 times per minute. You can count by watching your dog’s chest rise and fall for 30 seconds and doubling the number. If your resting dog is consistently breathing faster than 35 to 40 breaths per minute, particularly if you notice their belly moving more than usual with each breath, that suggests fluid may be accumulating. This is especially important to monitor if your dog is on heart medication, as a rising respiratory rate can mean the treatment needs adjusting.
Signs That Need Immediate Attention
Most weird breathing noises are not emergencies, but a few patterns demand urgent care. Check your dog’s gums by lifting their lip. Healthy gums are pink and moist. Gray, blue, or purple gums mean your dog isn’t getting enough oxygen, and this is a genuine emergency requiring immediate veterinary care. The same applies if gums are pale white or yellow.
Other red flags include open-mouth breathing with visible effort (neck extended, elbows pushed out, exaggerated belly movement), inability to settle or lie down, sudden collapse, or any breathing difficulty that seems to be getting worse over minutes rather than better. A dog that is struggling to get air in a way that looks panicked or exhausted needs to be seen right away, not monitored at home.
