A dog coughing by itself isn’t necessarily an emergency – but excessive coughing can be a sign of illness. Including heart disease, infection, or a breathing obstruction…some of which can be life-threatening. Here’s everything you need to know about the different types of coughing in dogs and what you can do to take care of your canine loved one. (Including a vet-approved recommendation: Activity Tracking.)

Why is my dog coughing?

In general, coughing is the body’s reaction to an irritant in the airway. As your buddy explores the world with their nose or mouth, they encounter germs, dirt, tiny bugs, bits of grass, and many other particles. If some of this material is breathed in, your dog may cough to expel it.

But if you’ve got a dog coughing:

  • Frequently,
  • In their sleep,
  • With changes in their breathing – like snoring or sleep apnea
  • or can’t seem to stop coughing once they start…

…then it’s time to take a closer look. All these signs could indicate something more serious.

Is my dog coughing or gagging?

Coughing and gagging may sound similar when they happen, but they’re not quite the same. A cough is caused when your dog forces air out of the mouth and throat. Gagging is more akin to vomiting, but nothing comes out except some phlegm or mucus.

Coughing can lead to gagging and vice versa – but either can happen on its own. Gagging is often the result of your dog gulping down large chunks of dry food or swallowing something distasteful. It’s a natural process to rid the body of the swallowed or partially-swallowed item.

What are the different types of dog coughs?

Pay attention to how your dog’s cough sounds so you can describe it to your veterinarian. This will help your vet decide the best way to care for the cough and make your pooch more comfortable. Which category below best describes your dog’s cough?

  • Dry, hacking, cough that is deep-sounding
  • Gagging and high-pitched cough
  • Wet and phlegmy
  • Deep and honking, like a goose

Each type of cough indicates a different problem. Take a video of your dog coughing and show it to your vet. This will help the vet decide if the cough signals an emergency or could be contagious, like kennel cough or canine influenza.

What are the symptoms of kennel cough?

The term “kennel cough” is a catchall for any inflammation of the dog’s trachea and lower airways.

  • It typically causes your dog to produce a deep, dry, honking cough.
  • Kennel cough is caused by several types of bacteria or viruses, but it produces only mild illness.
  • Left untreated, kennel cough can move into your dog’s lungs, leading to more severe problems like pneumonia or chronic bronchitis.
  • It’s also highly contagious and is often spread in group settings such as obedience classes, boarding facilities, or dog parks.

When should I bring my dog to a vet? 

Most cases of coughing in dogs are completely treatable. But your dog’s condition needs to be diagnosed in order be treated, so that means a trip to the vet. Bring along a video of your dog coughing in case your pup doesn’t cough during the appointment.

Bring your dog to the vet if your dog experiences any of these:

  • Your dog’s cough is getting worse
  • Your dog’s cough lasts more than 5 days
  • Your dog coughs after exercise
  • Your dog coughs after drinking or eating food 
  • Your dog coughs even when resting 
  • Lethargy – which you can catch on to early if you’ve been tracking your dog’s daily activity
  • Fever
  • Loss of appetite
  • Labored breathing

Your veterinarian can prescribe medication to alleviate the cough. Be sure to keep your pup away from other dogs until they are no longer contagious.

Likewise, the Bordetella vaccine and Canine Influenza vaccine can protect your dog from getting kennel cough. Your vet can administer them as an injection or nasal spray. Talk to your vet about these vaccines, especially if your dog is boarded frequently. 

Why is my dog coughing so much? 7 main reasons why

1) Foreign objects in the throat

Dogs sometimes swallow things that they shouldn’t, or they play with sticks or bones that can splinter and lodge in the throat. Coughing is your dog’s attempt to expel the foreign object.

But if the foreign object is wedged tightly in the throat, your dog won’t be able to clear it. Look around for clues to determine if your dog recently chewed on or ate something that could have lodged in the throat. If you suspect a foreign object is lodged in the throat, seek veterinary care as this could block the airway or cause infection.

Sometimes, the cough or gag is a result of your dog eating too fast and the food going down the “wrong pipe” (the trachea, which leads to the lungs, instead of the esophagus, which leads to the stomach). Just keep a close eye on your pup after an incident like this.

2) Environmental allergens

Pollen, smoke, fungi, and other inhaled allergens can cause coughing in your dog. If your dog has allergies, consider keeping them indoors during peak allergy season, or ask your veterinarian for medication to alleviate the symptoms.

3) Tracheal collapse

If your dog experiences tracheal collapse, their cough may sound like a honking goose. Tracheal collapse occurs when the cartilage surrounding the airway weakens.

Toy dog breeds and obese dogs have an increased risk of developing a collapsed trachea. Treatment for a collapsing trachea includes weight loss and medication to reduce coughing.

4) Pneumonia

A wet, phlegmy cough may indicate a buildup of fluid in the lungs. If the fluid becomes infected, then your dog will have pneumonia. This is a serious condition that requires immediate veterinary attention to protect your pet’s health.

One way to know if your dog might have pneumonia is to watch their breathing. If breathing is labored even when the dog is resting and not coughing, that may be a sign of pneumonia.

5) Heart disease

When your dog’s heart is not pumping effectively, fluid may start to accumulate around the lungs, resulting in a cough. You may notice the cough becoming more prevalent when your dog is lying down. Heart disease also can cause the heart to enlarge. Which, over time, can put pressure on the trachea – resulting in a cough as well.

Other reasons for coughing in dogs include heartworm disease. When not treated, heartworm disease can lead to heart disease. (Which is the main reason for the coughing.)

Heart disease is more likely to occur in senior dogs. Don’t put off a call to your vet – this is a serious condition.

6) Canine chronic bronchitis

When the tiny branches of your dog’s lower airways become inflamed, a persistent cough can develop. If your dog has coughed daily for more than two months, they may have canine chronic bronchitis. This chronic condition is unlikely to resolve, so treatment focuses on addressing the symptoms. 

Reverse sneezing, also known as paroxysmal respiration, may seem like coughing, but it’s not. In a reverse sneezing episode, a dog actually sucks air in rather than forcing it out. The reverse sneezing attack may last up to a minute, then it’s over – and your dog will probably act like nothing happened. Don’t be alarmed, but keep track of how often this happens. If reverse sneezing becomes a daily occurrence, contact your vet to rule out any other conditions.

Laryngeal paralysis is another condition that may seem cough-related. In laryngeal paralysis, the muscles that surround the voice box (larynx) become weak. Your pup may pant loudly and their voice may change. Always see your veterinarian when your dog experiences changes in breathing.

Lung cancer can cause persistent coughing in dogs. (However, thankfully, it’s not a common reason that dogs experience coughing.)

7) Canine influenza

Coughing, along with sneezing, runny nose, runny eyes, fever, and lethargy can signal canine influenza (dog flu). Ask your vet about supportive care for your pup, such as fluids and other medications to reduce fevers.

It’s important to alert your vet in advance if you are bringing a dog with canine influenza to the office – they may wish to keep your dog away from other pets to prevent the spread of dog flu.

Where an Activity Tracker can help you detect issues early

Sometimes it might take a few days for your dog to develop a full-blown cough. The signs they’re sick or struggling with an infection can be subtle and easy to miss – until they’ve worsened, that is.

💡Which is why vets recommend tracking your dog’s regular activity to catch on to health issues early.

“Keep track of your dog’s energy levels, especially how long they are able to walk.

If you notice significant declines, it could be a sign of pain, heart disease, or other illness.”

So you could jot down your dog’s symptoms in a journal – or use the actionable data from an Activity Tracker for dogs instead.

Tractive Activity Monitoring for dogs

Don’t be fooled by the “GPS” on your trusty Tractive device. With its built-in motion detector, yours picks up both on where your dog’s been off wandering – and for how long they’ve been on the move.

Which, over time, can help you figure out in numbers:

  • What’s a normal level of activity for your dog
  • How active your dog is compared to other, similar dogs – from your very own community leaderboard
  • If there’s a gradual (or even sharp) dip in your dog’s daily activity – which might signal they’re sick, injured, or in pain.

All of which can help you have a more productive conversation with your vet – and help you avoid a hefty, thoroughly preventable bill.

Are there some home remedies for my dog’s cough?

Persistent coughing can irritate the throat. So here are a couple of home remedies you could try:

  • Soothe your pup’s throat with honey. Add a spoonful of honey to a bowl of water, up to three times per day. 
  • Place a small humidifier near your dog’s bed can keep your pet’s throat from drying out.
  • If you don’t have a humidifier, invite your pup into the bathroom while you shower (but not in the actual shower or tub) for a bit of steam therapy. Close the bathroom door so the room gets extra steamy.
  • Allowing your dog to plenty of rest is important for recovery form any illness. Don’t force them to go on walks or engage in vigorous play. Their body just needs time to recover.

How to prevent coughs in dogs?

Sometimes, there isn’t any way to prevent coughing or gagging in your dog. But you can take some simple precautions to avoid life-threatening illness.

  • Keep your pup current on all vaccinations including the kennel cough vaccine.
  • Keep them away from unvaccinated or sick dogs.
  • Regular vet checkups can help with prevention, safeguard your pet’s health, and catch serious illnesses before they progress.

And finally…

💡Keep an eye on your dog’ activity – so you can catch on to a drop early on. (Which is often the first red flag they’re not doing so well, health-wise.)

“Absolutely love this tracker…it gives great insights on (our dogs’) activity and sleep levels.

I’m comforted knowing that if they started acting strangely or the data shifted drastically that we could take them to vet potentially before we would notice something wrong.

Can’t recommend this tracker enough!“
