Hearing your dog make a sudden, harsh coughing sound that seems like they’re choking is scary. You might rush over, check their mouth, and find nothing there. That raspy, honking cough can come from several common issues, and knowing the difference between an emergency and a minor irritation helps you stay calm and take the right next step. Let’s break down what that sound usually means, from kennel cough to reverse sneezing, and when you should head to the vet.
1. Kennel Cough: The Most Common Culprit
If your dog’s cough sounds like a dry, hacking honk followed by a gag or retch, kennel cough is the top suspect. It’s a highly contagious respiratory infection (like a human cold) that causes inflammation in the windpipe and voice box. Dogs often catch it at boarding facilities, dog parks, or grooming salons. The cough can be forceful enough to make them bring up a little white foam or mucus, which looks alarming but is usually just phlegm.
Most cases resolve on their own in one to three weeks, but you should still call your vet. They can rule out more serious issues and may recommend rest, a humidifier, or a mild cough suppressant. Keep your dog away from other dogs until the cough is completely gone to avoid spreading it. If your dog is a breed prone to respiratory issues, like a brachycephalic pup, the cough can hit harder, so extra monitoring is key.
Kennel cough is often called the “dog cold,” but it’s actually caused by several different viruses and bacteria. The classic “honking” sound comes from inflammation in the trachea, which is why it’s also called tracheobronchitis.
2. Reverse Sneezing: The False Choking Scare
Sometimes a dog makes a snorting, gasping sound that seems like they can’t breathe, but it’s actually a reverse sneeze. This happens when the soft palate gets irritated and spasms, causing the dog to rapidly inhale through their nose in a loud, choking-like burst. It’s common in small breeds and flat-faced dogs (like Bulldogs or Pugs), but any dog can do it.
Reverse sneezing episodes usually last 30 seconds to a minute and stop on their own. You can help by gently massaging your dog’s throat or covering their nostrils briefly to encourage them to swallow. It’s not harmful, but if it happens frequently or is accompanied by other symptoms like discharge or lethargy, have your vet check for allergies or nasal mites. For active breeds like Australian Shepherds who love to sniff everything on walks, this can happen from excitement or dust. If you have a smart, energetic Aussie, you might find them reverse sneezing after a big play session with their favorite puzzle toys for Australian Shepherds that get them worked up.
3. Collapsed Trachea: The Honking Cough
If your dog’s cough sounds like a goose honking, especially when they pull on the leash or get excited, a collapsed trachea could be the issue. This is most common in small breeds like Yorkshire Terriers, Pomeranians, and Chihuahuas, but larger dogs can have it too. The cartilage rings in the windpipe weaken, causing the airway to flatten and make breathing difficult.
You’ll notice the cough gets worse with exercise, heat, or pressure on the neck. Switching from a collar to a harness is the first and most important step. Using a harness reduces neck strain dramatically, and if you have a large breed like a Cane Corso, proper gear matters even more. Check out our guide on how to reduce neck strain with the best dog bowls for Cane Corsos to keep their posture comfortable while eating. For collapsed trachea, your vet may prescribe cough suppressants, anti-inflammatories, or even recommend weight management to reduce pressure on the airway.
“A harness is not just a fashion choice, it’s a medical device for dogs with a collapsing trachea.”
4. Foreign Object or Something Stuck
If the coughing started suddenly while your dog was chewing on a toy, bone, or stick, they might have something lodged in their throat or esophagus. Signs include frantic pawing at the mouth, drooling, gagging, and repeated swallowing. This is a true emergency if they can’t breathe or are turning blue. Do not stick your hand in their mouth, as you can push the object deeper. Perform a dog Heimlich maneuver if they are choking, and get to the nearest vet immediately.
For non-emergency cases where your dog is coughing but still eating and drinking, a small piece of food or grass might be irritating the throat. This usually passes on its own within a few hours. To prevent future issues, choose appropriately sized toys and chews. For example, if you have a powerful chewer like a Cane Corso, always supervise them with new items and consider whether Cane Corsos are good family dogs in terms of their play style and chewing habits before introducing certain toys.
5. Heart Disease and Other Serious Causes
A chronic, soft cough that gets worse at night or after exercise can be a sign of heart disease, especially in older dogs. When the heart isn’t pumping efficiently, fluid can back up into the lungs, causing a persistent cough. This is different from the sharp, honking sound of kennel cough. It’s often accompanied by fatigue, reduced appetite, and a swollen belly.
Other serious causes include pneumonia (wet, productive cough with fever), lungworm (coughing up blood), or even certain types of cancer. If your dog’s cough lasts more than a few days, is paired with lethargy, loss of appetite, or difficulty breathing, don’t wait. Schedule a vet visit for a full workup, including chest X-rays and possibly an echocardiogram. For large breed owners, understanding overall health is crucial. If you’re considering adding a Cane Corso to your family, knowing their predisposition to heart issues is part of responsible ownership.

When to Go to the Vet Immediately
Some situations require immediate veterinary care. Go to the emergency vet if your dog: is struggling to breathe, has blue or pale gums, collapses, is coughing up blood or large amounts of foam, or if they have a known heart condition and start coughing. Also, if your puppy or senior dog starts coughing suddenly, it’s always safer to get them checked. For most other cases, a video of the cough can be very helpful for your vet to diagnose the issue over the phone.
