Barking Cough or Laryngotracheitis: Symptoms, Complications, Diagnosis and Treatment

Coughing is an act as simple as every day that therefore goes unnoticed.

However, the cough may have very different origins, especially in children.

The medical clinic has made an inventory large enough to categorize, analyze and study all the spectra of cough, to the point of discerning without problems the origin of each of these.

Not all coughs are the same, mainly when we refer to babies.

This is the case of the colloquially called canine cough, which often manifests itself with frequencies in babies; it is a cough with very particular characteristics, which every parent should identify to know what treatments to take.

What is the Perruna Cough?

The clinical name of this condition is laryngotracheitis or laryngeal croup, which is analyzed and categorized among the infections that significantly compromise the so-called upper respiratory tract.

The majority of the medical community agrees that in the case of laryngeal croup, its presence is due to contact with infectious viruses that affect both the bronchi and larynx and trachea.


Generally, in contact with the virus is that inflammation of these areas subsequently occurs, obstructing their normal development and producing the particular cough, the dog cough, which is nothing more than a somewhat aphonic cough, which can have a small wheezing

Parainfluenza is the name of the virus responsible for the inflammation of these organs already mentioned and the expulsion of abundant mucus, mostly in babies, and especially in climatic seasons characterized by cold and humidity, as well as it is winter.


According to the specialized medical literature, the croup of croup or dog can manifest itself in 2 different ways in the person who suffers it. The classification used is spasmodic croup and laryngotracheobronchitis.

Spasmodic croup: This occurs fortuitously in the person, mostly at night, accentuating the hoarse cough and throat stridor.

As it has been said, it is manifested mainly in children, and precisely because of its unpredictable nature, its symptoms likewise cease without further ado, especially that of fever.

However, this fever could develop in the following nights in the same way in a fortuitous way.

Laryngotracheobronchitis: Unlike spasmodic croup, laryngotracheobronchitis does not appear or manifest abruptly but is preceded by the cold that will evolve into the croup.

The tendency is that this last form of croup is suffered in babies whose ages do not exceed three years. The progression or development of the condition is usually slow.

The symptomatology generated in the patient is, apart from fever, a more incredible respiratory difficulty with stridor settling, nasal flapping, narrowing of the ribs, and accelerated breathing.

The improvement of these symptoms depends on the child’s emotional state; therefore, the symptoms will increase if he is very excited and distressed. Otherwise, the levels of intensity of the same will be reduced.


The most predictable complication in the case of dog cough is that inflamed organs linked to the air part of the breathing are significantly obstructed to the point that the child would eventually require artificial respiration.


As in any disease, the history is a vital instrument to demonstrate the mode and presentation of the illness analyzed. In the case of these forms of infectious cough, it is necessary to know if there was a fever, for example.

In the case of medical examination as a method for diagnosis, the doctor will quickly check the child’s general condition to rule out urgency.

Then listen to the child to trace the typical signs of cough croup, such as throat and swollen bronchi, and atypical aphonia in cough, among others.

Because it has been shown that in the case of children, the worsening of the disease is in intimate relation with the emotional state of the same, additional tests have been dispensed with to strengthen the diagnosis.

Suppose the doctor, however, feels that he needs to rule out other possible processes that may be involved in the condition being analyzed. In that case, he will need to make the child x-rays to assess the possible presence of foreign bodies.


Depending on the level of affectation, the treatment will vary. Then, a relatively moderate medicine will be prescribed in those cases in which the disease has not been so invasive. The humidifiers are decisive for the improvement of the condition.

Similarly, with the help of parents, it is necessary to use their inventive conditioning of the environment in such a way that the levels of stress of the child completely deplete.

Being nervous would imply a relapse and worsen the symptoms in the case of them.

However, suppose the symptoms suffered from the disease have not been so mild. In that case, treatment should focus on administering corticosteroids such as budesonide, which are orally in the form of syrup, or, failing that, presentations with devices such as masks.

In those cases of urgency (which are rare), the child will inevitably require artificial respiration and even a dose of adrenaline to stabilize it.

As you can see, what we know as dog cough is one of how the croup can evolve, which also implies the dog, stridor, and aphonia as distinctive signs of croup.

Precisely because of the croup’s mutations, it is always advisable to maintain constant and fluid communication with the child’s doctor to prevent significant problems in time.

Because the emotional factor in the case of croup plays a decisive role in its development.

Finally, these respiratory and infectious diseases do not present negative indicators in terms of mortality. Usually, the patient improves within a few days or even hours, depending on the severity of the symptoms.
