Hearing your dog keep hacking like there’s something stuck in their throat can be alarming and confusing.
While the sound may sometimes be harmless, constant hacking is often a signal that your dog is uncomfortable or dealing with an underlying health issue.
We outline the common causes of a dog hacking like something is stuck in their throat, what you can do at home, and when to seek veterinary help.
Dog Keeps Hacking Like There's Something in Their Throat — Why It Happens
Dogs often hack as though something is stuck in their throat due to kennel cough, throat irritation, tracheal collapse, foreign objects, allergies, or respiratory infections. This reflex is the body’s way of trying to clear the airway or respond to irritation.
In some cases, it passes quickly, but frequent or prolonged hacking suggests that your dog’s airways, lungs, or heart may be involved.
Dog Keeps Hacking Like There’s Something in Their Throat: Common Causes
Kennel Cough
Kennel cough is one of the most common reasons dogs keep hacking like something is stuck in their throat.
This contagious respiratory condition causes a dry, honking cough that can sound like gagging or retching.
It spreads easily in places where dogs gather, like boarding facilities or dog parks. While mild cases can clear on their own, kennel cough can become more serious in puppies, senior dogs, or those with weakened immune systems.
If untreated, it can progress to pneumonia, making veterinary evaluation important if symptoms persist.

Tracheal Collapse
In small breeds such as Yorkies, Chihuahuas, and Toy Poodles, tracheal collapse is a frequent cause of hacking.
The weakened cartilage of the windpipe flattens when the dog breathes, producing a loud honking sound that often mimics choking.
Episodes worsen with excitement, exercise, or pressure from collars. Over time, the condition can become chronic and interfere with breathing.
Tracheal collapse often requires long-term management through medications, lifestyle changes, weight control, or in severe cases, surgery.
Foreign Object or Obstruction
Sometimes a dog keeps hacking because something truly is stuck in the throat. This may be food, grass, a small toy piece, or even a bone fragment.
Dogs experiencing this often suddenly begin gagging, pawing at the mouth, drooling excessively, or showing distress.
If the object completely blocks the airway, it can become life-threatening within minutes. Emergency veterinary care is essential if you suspect your dog has inhaled or swallowed something that won’t pass on its own.
Allergies or Environmental Irritants
Just like humans, dogs can suffer from seasonal allergies or react to dust, smoke, or cleaning products. These irritants can inflame the throat and trigger repeated hacking as though something is stuck.
This type of hacking usually appears alongside watery eyes, sneezing, or itchiness. While not usually dangerous, allergies can make dogs uncomfortable and may worsen if untreated.
Managing environmental factors and discussing safe antihistamine use with a veterinarian can help provide relief.
Heart Disease
Coughing or hacking that seems like throat irritation may actually stem from heart disease.
When the heart is weakened, fluid can accumulate in the lungs, creating pressure that leads to persistent coughing and gagging.
Dogs with heart disease often show other symptoms too, like reduced stamina, difficulty breathing after activity, or fainting episodes.
Because heart disease can be serious and progressive, persistent hacking in older dogs especially should not be ignored.
Pneumonia or Bronchitis
More serious respiratory illnesses such as pneumonia or bronchitis can also cause dogs to hack as though clearing their throat.
In these cases, the hacking is usually accompanied by fever, nasal discharge, lethargy, or loss of appetite.
Pneumonia in particular is dangerous, as it fills the lungs with fluid and makes breathing difficult.
Without treatment, it can become life-threatening. Veterinary care is crucial if your dog’s hacking is paired with signs of illness or fatigue.
What to Do If Your Dog Keeps Hacking Like There’s Something in Their Throat
If your dog keeps hacking like there’s something stuck in their throat, first observe carefully. Take note of how often it happens, when it started, and whether it worsens during certain activities such as eating, drinking, or playing.
Keep your dog calm and avoid stress or strenuous activity while they’re symptomatic. Switch from a neck collar to a harness to reduce throat pressure, especially in small breeds.
Make sure your dog has access to fresh water, as hydration can soothe irritation. Keep your home free of smoke, dust, or strong scents that could make coughing worse.
If you suspect allergies, regular cleaning and use of air purifiers may help reduce triggers. However, always consult your veterinarian before giving medications, as many human products are unsafe for dogs.
If hacking seems mild and your dog otherwise feels well, you may monitor at home for a few days. But if gagging is constant or your dog seems distressed, veterinary attention is the safest course of action.
When to Call or Visit Your Vet
Not all coughing is serious, but constant hacking is not something to ignore. Seek immediate veterinary care if your dog is struggling to breathe, producing bloody mucus, or has sudden episodes of distress.
If hacking persists for more than a few days without improvement, schedule a veterinary visit. Long-term throat irritation can signal kennel cough, tracheal collapse, or even heart issues that benefit from early diagnosis.
Emergency care is also necessary if your dog suddenly starts gagging after chewing on a toy, bone, or stick, since this could mean something is lodged in the airway.
The main rule: if hacking is ongoing, severe, or paired with additional symptoms like lethargy, fainting, or labored breathing, call your veterinarian right away.

Key Takeaway
If your dog keeps hacking like something is stuck in their throat, it may be caused by something mild such as kennel cough or allergies, or something more serious like tracheal collapse, heart disease, or a foreign object.
While occasional gagging may not be urgent, frequent or severe hacking deserves a veterinary check.
By keeping your dog comfortable at home, removing irritants, and seeking professional advice when needed, you can protect your dog’s health and ensure they get the right treatment.
