A dog with a dry cough and hacking sound can be alarming, especially when the symptoms come on suddenly or worsen over time.
These respiratory changes can point to irritation or even a more serious underlying condition affecting the airways or lungs.
We outline the common causes of a dry cough and hacking in dogs, what you can do at home, and when to seek veterinary help.

Dog Dry Cough and Hacking: Why It Happens
A dry cough and hacking sound in dogs often happens when the throat, airway, or lungs become irritated or inflamed, and several conditions can trigger this uncomfortable symptom. Your dog may cough due to kennel cough, allergies, tracheal irritation, heart disease, or even something stuck in the throat.
Dry coughing can also appear when a dog inhales dust, breathes cold air, or is recovering from a recent respiratory infection.
In many cases, the sound is created by swelling in the airway that makes every breath feel scratchy or ticklish, prompting the dog to cough in an attempt to clear it.
These symptoms can be mild and temporary, or they may indicate something more serious that needs prompt veterinary attention.
Dog Dry Cough and Hacking: Common Causes
Tracheal Collapse
Tracheal collapse occurs when the rings that support the windpipe weaken, causing the airway to flatten during breathing.
This condition is more common in small breeds like Yorkies, Pomeranians, and Chihuahuas, and it often presents as a repetitive dry cough and hacking that sounds like a goose honk.
A dog with tracheal collapse may cough more when excited, pulling on the leash, or exposed to smoke or perfume.
The airway becomes irritated each time it narrows, which triggers the hacking sound. Over time, the cough may progress, making it difficult for the dog to breathe comfortably. Dogs with this condition often cough for years if it is not managed properly.

Allergies
Dogs exposed to dust, pollen, smoke, air fresheners, or mold may start coughing and hacking due to inflammation in the airways.
Allergies make the respiratory lining sensitive, causing swelling that triggers coughing even when nothing is trapped in the throat.
A dog with allergies may also show sneezing, watery eyes, or occasional throat clearing. Dry air, especially during winter or in air-conditioned homes, can worsen the hacking sound by drying out the airway tissues.
While allergies may seem mild, chronic irritation can make coughing more frequent and uncomfortable, especially at night.
Kennel Cough
Kennel cough is one of the most common reasons for a dog dry cough and hacking, especially when the cough sounds like a loud “honking” noise.
This contagious infection irritates the trachea and upper airways, making each breath feel rough and sensitive. Dogs can pick it up at kennels, groomers, dog parks, or anywhere canines gather.
The dry, hacking cough often gets worse at night, with excitement, or during leash pulling. Even though kennel cough is usually mild, the irritation can linger for weeks, especially in seniors or dogs with sensitive airways.
Infections caused by bacteria, viruses, or a combination of both can inflame the throat and trachea, which explains why the cough sounds deep and persistent.
Heart Disease
Heart disease can cause a dog dry cough and hacking when an enlarged heart presses against the airways or when fluid begins to accumulate in the lungs.
This type of cough often sounds dry, persistent, and occurs more when the dog is resting or lying down.
Because heart disease affects blood flow and lung function, the airway may feel restricted or congested, prompting the dog to cough in an attempt to relieve pressure.
Dogs with heart-related coughs may also show fatigue, reduced stamina, or breathing changes. This cause is more common in senior dogs but can occur at any age depending on the breed.
Throat Irritation
Sometimes a dry cough and hacking comes from a simple mechanical irritation. A dog may inhale dust, drink water too fast, or get a piece of grass or food stuck near the throat. This causes repetitive dry hacking as the dog tries to clear the sensation.
In more serious cases, a foreign object can partially obstruct the airway. Dogs may paw at their mouth, swallow repeatedly, or appear anxious. Even when the object is no longer present, the throat may remain irritated for hours or days, resulting in a persistent cough.
Respiratory Infection
While pneumonia typically causes wet coughing, early stages or milder infections can create a repetitive dry cough and hacking sound. Inflammation deep in the lungs makes breathing uncomfortable, and the dog may cough to reduce pressure or irritation.
Dogs may also show fever, lethargy, or faster breathing, although mild cases can start with only a dry cough. Pneumonia always requires prompt veterinary care, as untreated infections can progress quickly.

What to Do If Your Dog Has a Dry Hacking Cough
Start by monitoring how often the cough occurs and whether anything makes it worse. Give your dog a calm, quiet space to rest because excitement and movement can intensify irritation in the airway.
Keeping your home’s air humidified may help soothe the throat and reduce the dryness that triggers coughing. Avoid using sprays, scented candles, smoke, or strong cleaning products until your dog is fully recovered, as these can worsen respiratory irritation.
If your dog pulls on the leash, switch to a harness instead of a collar. Pressure on the throat can worsen coughing, especially in dogs with tracheal sensitivity or collapse. Encouraging your dog to drink small amounts of water can also help keep the throat moist, which may reduce hacking episodes.
For dogs recovering from kennel cough or minor irritation, gentle supportive care often improves symptoms within a few days. However, if the cough persists longer than a week, becomes more intense, or is accompanied by breathing changes, it’s important to get veterinary guidance.
A vet may prescribe cough suppressants, antibiotics, anti-inflammatories, or medications to ease airway pressure depending on the underlying cause.
When to Call or Visit Your Vet
If your dog’s dry cough and hacking becomes frequent, severe, or lasts more than several days, veterinary evaluation is recommended. A cough that worsens at night, during rest, or when lying down can signal heart-related issues, which require prompt testing and treatment.
If your dog shows any breathing difficulty, wheezing, or fast or shallow respirations, seek immediate care because these can be early signs of airway obstruction or lung involvement.
Coughing accompanied by lethargy, fever, lack of appetite, or nasal discharge may point to infection or pneumonia, both of which need timely treatment.
Dogs who make gagging noises repeatedly or seem like they might have something stuck in the throat should be seen quickly to rule out foreign bodies.
Senior dogs, puppies, or dogs with pre-existing heart or respiratory conditions should be assessed sooner rather than later. Their lungs and airways may not handle prolonged irritation as easily, and early care can prevent complications.

Key Takeaway
A dog dry cough and hacking sound can come from something as simple as throat irritation or something as serious as heart disease or tracheal collapse.
Paying attention to when the cough happens, how your dog behaves, and whether other symptoms appear can help you decide if home care is enough or if a vet visit is needed. With early support and proper treatment, most dogs recover quickly and breathe comfortably again.
If something feels off or the cough doesn’t improve, reaching out to your veterinarian is always the safest choice.
