A dog that is constantly hacking can be alarming for any owner. Persistent coughing or gagging sounds may point to something simple like throat irritation, or more serious issues.
We outline the common reasons for constant hacking in dogs, what you can do at home, and when to seek veterinary help.

Dog Constantly Hacking — Why It Happens
Dogs constantly hacking often suffer from airway irritation, infections, allergies, or more serious conditions like heart disease or collapsing trachea. In some cases, something as minor as dust, smoke, or a foreign body can trigger the reflex. But if hacking becomes frequent, it may signal kennel cough, pneumonia, or even cardiac problems.
Some breeds are more prone due to anatomical structure.
Dog Constantly Hacking: Common Causes
Kennel Cough
Kennel cough is one of the most common reasons for persistent hacking in dogs. It is a contagious respiratory infection that spreads quickly in places like kennels, dog parks, and grooming salons.
The hacking cough is often described as a dry, honking sound. Dogs may still eat and drink normally but will hack frequently, especially after exercise or excitement.
While many mild cases resolve with rest, kennel cough can progress to pneumonia if left untreated, making veterinary evaluation important.

Collapsing Trachea
Small breed dogs such as Chihuahuas, Yorkies, and Pomeranians are especially prone to tracheal collapse. This condition occurs when the cartilage rings of the trachea weaken and cause the airway to narrow.
Hacking often sounds like a goose-honk cough, worsening when the dog is excited, pulls on a leash, or after eating and drinking.
This condition can be chronic and may require long-term management with medications or, in severe cases, surgery.
Heart Disease
Heart problems can also cause a dog to hack persistently. When the heart isn’t pumping effectively, fluid can build up in the lungs, leading to coughing and difficulty breathing.
Owners may notice their dog hacking more at night or after lying down. Other symptoms can include lethargy, loss of appetite, and exercise intolerance.
Since heart disease can progress quickly without treatment, veterinary care is crucial.
Allergies or Irritants
Environmental triggers like pollen, dust, cigarette smoke, or strong cleaning chemicals can irritate a dog’s airway.
Dogs with allergies may experience constant hacking, sneezing, watery eyes, or itchy skin.
While occasional coughing from irritants may not be serious, ongoing hacking can signal chronic irritation or allergic bronchitis that needs management.
Foreign Body in the Throat
A lodged piece of grass, food, or a small toy can cause a dog to hack repeatedly as the body attempts to clear the obstruction.
This is usually sudden in onset and may be accompanied by gagging, pawing at the mouth, or drooling. In some cases, it can be life-threatening if the airway is blocked.
Quick veterinary evaluation is essential if this is suspected.
Pneumonia or Other Infections
Dogs with pneumonia or serious respiratory infections may hack constantly due to fluid and inflammation in the lungs.
This hacking is often moist and productive, and may be accompanied by fever, lethargy, and loss of appetite. Infections can worsen quickly and need prompt veterinary care.
What to Do If Your Dog Is Constantly Hacking
If your dog is hacking but otherwise acting normal, try to monitor frequency and triggers. Remove potential irritants like cigarette smoke, perfumes, or dusty bedding from their environment.
Offer plenty of fresh water to help soothe the throat. Keeping your dog calm and avoiding excessive excitement or leash pulling may reduce coughing episodes.
For dogs with mild kennel cough, supportive care and rest may be enough, but you should still contact your vet for advice. Never give over-the-counter cough suppressants without veterinary approval.
If you suspect something stuck in the throat, or if hacking persists for more than a few days, schedule a vet visit.
When to Call or Visit Your Vet
Seek veterinary care immediately if your dog’s hacking is accompanied by difficulty breathing, blue gums, or sudden collapse.
You should also call your vet if the hacking is persistent, worsening, or disrupting sleep. Dogs coughing up phlegm, blood, or showing lethargy need urgent attention.
Older dogs with a history of heart problems should always be checked promptly when hacking begins.
Puppies, small breeds, or dogs with other underlying conditions are at higher risk of complications and should not be left without care.

Key Takeaway
Constant hacking in dogs is a symptom that should never be ignored. While it may stem from something simple like throat irritation, it can also signal infections, heart disease, or airway problems.
Pay close attention to how often your dog hacks, when it occurs, and whether other symptoms are present. At-home care may help with mild irritation, but persistent or severe cases need veterinary evaluation.
With timely diagnosis and treatment, many causes of dog constantly hacking can be managed successfully, helping your dog breathe easier and feel more comfortable.
