With enough rest and a clean environment, your dog will recover within 2-3 weeks.


Dog coughing at night. Chronic Bronchitis in dogs


Chronic bronchitis leads to blockage of your dog’s airways, as a result of irreversible inflammation of the walls of bronchi. Bronchi refer to the branches of smaller airways from the trachea. They are responsible for allowing oxygen exchange in the alveoli. Now, those are medical terms, let’s look at it in layman’s lingo.

Chronic bronchitis causes irreversible damage to your dog’s lungs and usually lasts for longer compared to most respiratory diseases. The illness is caused by various factors among them parasites and bacterial infections. Your vet will be able to diagnose your dog for conclusive results.

Dog coughing at night. A cough associated with heart disease


One of the most common symptoms of heart failure is chronic coughing over a period of time. Congestive heart failure occurs when the heart cannot deliver enough blood to the body. Due to this, fluid is reversed back to the lungs and abdomen. This will lead to chronic coughing in dogs.


Dog coughing at night. Heart disease in dogs


Usually, this will be termed congestive heart failure. It is caused by your dog’s failure to deliver blood to the body parts. This leads to the accumulation of fluids in the lungs, causing breathing difficulties among other dysfunctions.

In medical terms, congestive heart failure is caused by mitral valve insufficiency, causing blood to leak back into the heart. Heart failure can be on one side of the heart, and sometimes both sides depending on severity. It is important to keep an eye on your dog if you are afraid he might suffer heart failure. This is because the condition can be deadly if left untreated.

Before we look at the symptoms of heart failure in dogs, let us quickly list the risk factors that may contribute to congestive heart failure in dogs;


The size of your dog


Large dogs are at high risk of dilated cardiomyopathy, which is known to cause congestive heart failure. This condition means that your dog’s heart has enlarged and thus cannot pump blood as it is supposed to. It is important to always have your dog checked for CHF in case you own a large canine friend.




Smaller breeds of dogs have been named to be at higher risk of getting heart failure at some point. These breeds, including Chihuahuas and poodles. This is due to their risk to contract degenerative valve disease which makes fluid leak back into the heart. You should have your puppy checked up by the vet regularly.



Older dogs are at risk of heart failure, especially dogs over the age of 16 years.





Adult heartworms may clog the heart leading to improper function of the heart. However, we will discuss this later on.



This is especially caused by poor diet and lack of exercise. You should look into what you feed to your dog as well as schedule his exercises.


Dog coughing at night. Symptoms of Congestive Heart Failure


Some of the symptoms of congestive heart failure may include a persistent cough which is mostly accompanied by breathing difficulties. Your dog may appear tied which may result in exercise intolerance.
He may also have reduced energy levels and excessive panting which may lead to decreased activity and need to rest. You may notice general weight loss in your dog and swollen

Your vet will be able to diagnose your dog through X-rays, blood, and urine tests to rule out any other medical conditions. The vet may also conduct a heartworm test and ultrasound for a conclusive diagnosis. After this, your vet will recommend the necessary treatment for your dog. These might include medication to correct irregular heartbeats as well as slow the fluid accumulating in the lungs.

In severe cases, the vet may recommend surgery to correct the faulty valves. In addition, you may need to change your dog’s diet into a low-salt diet to manage the condition.


Heartworm Disease


Heartworms can actually be life-threatening if left untreated since they can clog the heart. Well, they actually live in the dog’s body, and if not treated, they might cause critical heart conditions. One thing for sure is that it is quite manageable to treat heartworm disease but difficult. The best approach for this is to prevent diseases.

The diseases are transmitted through mosquito bites, especially in areas with wildlife. The parasite is deposited into the host’s body. It can last up to 7 months before the worm becomes an adult, which will cause your dog medical problems.

Unfortunately, in the early stages of heartworm disease in dogs, you may not notice any symptoms. However, when they start showing, your dog may experience mild persistent cough as well as exercise intolerance. He may also appear tired after limited activity and have lower stamina than usual.

When heartworms grow into adult worms, they will lead to the blockage of the blood flow in the heart. This will contribute to possible heart failure which is life-threatening to your dog. This may also cause blood leakage into the lungs and mucus in the windpipe and thus inducing cough.




Treatment of heartworm is time-consuming and costly and sometimes may lead to complications. This is especially after surgery to clear the blockage in the heart. However, prevention is cost-effective and leaves your dog healthy.

Since we cannot be able to tell what region has a prevalence of heartworm disease, it is wise to always treat our dogs. You can do this by use of preventive medicine which is mostly oral pills or even topical skin creams and products. Your vet should be able to recommend the best medication to use. Preventive medicine is usually effective in killing the larvae heartworms before they become adults.

We have already stated that heartworm disease is transmitted through mosquito bites. What are some of the risk factors for heartworm disease?


Risk factors contributing to heartworm disease


It is difficult to predict the risk factors for heartworm disease but we have managed to draw a few. For instance, the environment in which you live could be a contributing factor. However, the disease is a potential threat in so many parts of the world, which is why you should always treat your dog.

However, the availability of wild animals in your area might put your dog at risk. This is because mosquitoes might bite a wild animal and later bite your dog. It is important to note that heartworms can also be found not only in pets but also in wildlife animals.

Some other regions are more prevalent in heartworm disease than others. This means that you will have to regularly treat your dog against the disease.


Laryngeal Paralysis


This is another cause of coughing in dogs that can be influenced by various factors. However, the cause of laryngeal paralysis has not been well defined although it can be hereditary. Some breeds are at more risk of laryngeal paralysis than others.

Age is also another contributing factor to the disease, which affects the voice box of your dog. Breeds that are susceptible to laryngeal paralysis include the Siberian Husky and Dalmatians. Untreated infections and neuromuscular diseases also contribute to the paralysis of the larynx. Obesity can make your dog’s condition worse.

When the voice box fails, your pet will have trouble breathing, especially in warm climates. This makes it hard for him to bark or perform any vocal activities.
Not only does age contribute to laryngeal paralysis but also the size of your dog. Larger breeds are at higher risks than smaller breeds of dogs. This condition is usually mistaken for old age as well as arthritis if not well diagnosed by a vet.




Some of the symptoms of Laryngeal paralysis include coughing, wheezing, and panting. Your dog may also experience distress in breathing especially in warm surroundings and weight loss. He might find it difficult to exercise or perform any physical activities.

Unfortunately, this disease can be life-threatening if left untreated. The vet might ask about your dog’s history during diagnosis as well as the breed of your dog. He will perform blood and urine tests to rule out any other infections before making a conclusive examination.



Treatment may involve surgery to correct the voice box.

You should, however, make sure that your dog is not in warm and poorly ventilated places while awaiting surgery. The vet might also put your dog on sedation and oxygen therapy administered in the vet care. In case you are taking care of your dog at home, refrain from dog collars that may put pressure on the larynx.


Tracheal collapse in dogs


A honking cough could mean that your dog has a tracheal collapse, which is common in obese dogs. Let us look at collapsed trachea in dogs further;

This is a condition that has been largely influenced by the domestication of dogs. Natural dogs will weigh about 40 pounds but through breeding, we have been able to alter the genetics of our dogs. We have been able to come up with smaller breeds of dogs. For instance, we have poodles and Chihuahuas that have smaller trachea, better known as the windpipe.

Even though they are born with strong windpipes, age and weight could also contribute to this condition. One of the very first signs of tracheal collapse is usually a honking cough with difficulty in breathing. barking or any form of strain will make it even worse.
The condition can be diagnosed through radiography by your vet. You should always have your dog checked if he is coughing because it is never a good sign.


Kennel dog cough


This is the most common reason why most dogs cough at night and it is treatable. Kennel cough is quite common among canines, and unfortunately, it is also highly contagious. Did you leave your dog at day-care service and now he appears to have a cold? This could be a kennel cough affecting your canine friend.

As common as kennel cough is, it can be severe especially in puppies and dogs with a weakened immune system. Also known as canine infectious tracheobronchitis, the disease is transmitted through three main ways;


i) Airborne droplets

As mentioned earlier, kennel cough is quite contagious among dogs. If your dog comes into contact with infected airborne droplets from an infected dog, he is likely to contract the disease. For instance, one of the most common symptoms of this infection is coughing and sneezing. When an infected dog coughs, emitting droplets to the air, another dog in the same room or kennel is likely to contract the disease.


ii) Direct contact

This is also another risk, especially if you have a social dog who loves to rub his nose with his friends. Through direct contact, your dog might come across infected nasal fluid and contract the disease. It could be that you took him out to the dog park, show, or even training groups.


iii) Contaminated surfaces

This is the reason why you should always feed your dog in a clean and exclusive bowl. Even if you own two canine friends, it is important to always make sure that each has his own bowl. This will limit the risk of getting infected.

Dogs will eat and lick their bowls after a satisfying delicacy, leaving his saliva and other fluids. In the case where one dog is infected with kennel cough, there is a likelihood of transmitting it to the other.
Even though a kennel cough is treatable, it can turn out to be quite severe in immune-compromised dogs as well as puppies younger than 6 months.


Symptoms of Kennel cough in Dogs


Kennel cough can be viral or even bacterial, depending on the causal agent. If your dog has kennel cough, he might show the following symptoms;

Fatigue – like the human flu, a kennel dog will put your pup down for weeks. He is going to be tired with no interest to partake in the physical activities he used to. Due to decreased energy levels, he might develop the need to rest more often than usual.

Other dogs will cough in their sleep while walking or carrying out any other activities.

Fever – Your dog will develop a fever when his body is trying to fight all the pathogens. Usually, the fever is mild and nothing to worry about. However, dogs with symptoms of kennel cough should be taken to the vet for a conclusive diagnosis.

Nasal discharge – Just like humans, dogs will experience similar symptoms to those of influenza while dealing with kennel cough. These might include a running nose with nasal discharge. It is important to remember that the discharge can actually transmit the disease to another dog.


Diagnosis and Treatment


Kennel’s cough is not difficult to examine and diagnose. Treatment involves about two weeks of rest in combination with antibiotics. The vet might recommend antibiotics to prevent a secondary infection while your dog recovers.

To manage kennel dogs, you should provide your dog with fresh water at all times as well as food if he is able to eat at all. The vet might also recommend cough medication and isolation from other dogs for a while. This is done to prevent transmission of the disease to other dogs to prevent any secondary infection your dog might contract.

As your dog recovers, you should also make sure that your dog is in a well-ventilated room to avoid suffocation and strain the respiratory system. You may also involve your dog in moderate exercises as he gets better. This will help avoid some behavioral vices among others.
