Hearing your dog keep hacking up nothing can be worrying and unsettling. The sound often mimics gagging, choking, or retching, but nothing ever comes out.
Dog owners naturally wonder if something is stuck in their dog’s throat or if it’s a sign of a more serious health problem.
We outline the common causes of a dog hacking up nothing, what you can do at home, and when to seek veterinary help.
Dog Keeps Hacking Up Nothing — Why It Happens
When a dog keeps hacking up nothing, it usually means the airways, throat, or lungs are irritated even though no mucus or foreign object is being expelled. This can be caused by kennel cough, allergies, collapsing trachea, throat irritation, or even heart disease.
Sometimes the cough is dry and repetitive, while in other cases it’s triggered by exercise, excitement, or pressure on the throat.
Although occasional hacking may not be serious, constant or worsening symptoms often point to an underlying health issue that needs veterinary attention.
Dog Keeps Hacking Up Nothing: Common Causes
Kennel Cough
One of the most common causes of a dry, hacking cough where nothing comes up is kennel cough. This contagious respiratory infection spreads quickly in places like kennels, grooming salons, or dog parks.
The hallmark symptom is a deep, honking cough that sounds like your dog is trying to clear their throat but can’t. Some dogs may also retch or gag afterward without producing anything.
Mild cases sometimes resolve on their own, but puppies, older dogs, or those with weakened immune systems can worsen quickly. Veterinary care may include antibiotics, cough suppressants, and rest.

Collapsing Trachea
Collapsing trachea is another frequent culprit, especially in toy breeds like Yorkies, Pomeranians, and Chihuahuas. The trachea weakens and narrows, causing airways to partially collapse during breathing.
This leads to a distinctive, dry, honking cough where nothing comes up. The coughing often gets worse with excitement, pulling on a collar, or after eating and drinking.
Although it’s a chronic condition, management with medications, lifestyle adjustments, and switching to a harness instead of a collar can greatly improve quality of life. Severe cases may require surgical correction.
Allergies and Environmental Irritants
If your dog keeps hacking up nothing, allergies or irritants may be to blame. Dust, pollen, cigarette smoke, cleaning sprays, or mold can all trigger coughing episodes.
This type of cough is usually dry and persistent, without any mucus. Dogs may also have watery eyes, sneezing, or itchy skin if allergies are involved.
Limiting exposure, using air filters, and speaking with your vet about antihistamines or anti-inflammatory medications can help ease your dog’s discomfort.
Throat Irritation or Foreign Body
Sometimes dogs hack repeatedly because something has irritated their throat. This could be a small piece of grass, a dust particle, or food that scratched the lining. In some cases, it may also signal a foreign object that’s stuck but not completely blocking the airway.
Owners may notice their dog coughing suddenly, pawing at their mouth, or acting restless. The cough may be dry, repetitive, and unproductive.
If the irritation doesn’t resolve quickly or if your dog seems distressed, veterinary attention is important to rule out obstruction or injury.

Heart Disease
Coughing that produces nothing can also be linked to heart disease, especially congestive heart failure. When the heart struggles to pump effectively, fluid builds up around the lungs, irritating the airways.
This leads to a repetitive hacking or dry cough, often worse at night or after exercise. Dogs may also appear tired, weak, or breathe heavily.
Heart-related coughs require veterinary diagnosis and treatment. Medications to manage fluid buildup and support heart function can make a big difference.
Pneumonia or Bronchitis
Although hacking up nothing is usually dry, sometimes it signals early stages of pneumonia or chronic bronchitis. These conditions inflame the airways, causing coughing even when no mucus is expelled.
Dogs with pneumonia may develop fever, lethargy, or loss of appetite, while chronic bronchitis tends to cause long-term dry coughing that worsens with activity.
Both conditions require veterinary care. Pneumonia is especially serious and may need hospitalization and antibiotics.
What to Do If Your Dog Keeps Hacking Up Nothing
If your dog keeps hacking up nothing, start by keeping them calm and comfortable. Excitement, exercise, or pulling on a collar can make the coughing worse, so quiet rest is helpful.
Provide fresh water and encourage hydration, as this soothes irritation. Running a humidifier in your home can also ease airway dryness, particularly in winter or dry climates.
Switching from a collar to a harness prevents unnecessary throat pressure, especially if your dog tends to pull on the leash. This is especially important for small breeds prone to tracheal problems.
You can monitor mild cases at home for a few days, particularly if your dog is otherwise healthy and energetic. However, if the hacking continues, worsens, or is paired with other symptoms, schedule a veterinary visit to identify the underlying cause.
When to Call or Visit Your Vet
Not every dry hacking cough is an emergency, but there are times when veterinary care is essential.
Seek immediate help if your dog is struggling to breathe, collapses, has blue or pale gums, or is coughing continuously without relief. These can be signs of a blocked airway, severe infection, or advanced heart disease.
You should also call your vet promptly if your dog’s hacking is accompanied by fever, lethargy, appetite loss, or difficulty exercising. Puppies, seniors, and dogs with preexisting health conditions are more vulnerable and should be checked sooner.
Even if your dog seems fine otherwise, a cough that lasts more than a week should always be evaluated to rule out chronic or progressive problems.

Key Takeaway
If your dog keeps hacking up nothing, it’s often due to kennel cough, allergies, collapsing trachea, or irritation in the throat.
Sometimes it may be a warning sign of heart disease or a respiratory infection that requires prompt treatment.
While mild, short-lived coughing can be monitored at home, persistent or worsening symptoms should always be checked by a veterinarian.
With timely care and the right management, most dogs with a hacking cough can return to breathing comfortably and living happily.
