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

Coughing is an act as simple as everyday that therefore goes unnoticed.

However, the presence of cough may have very different origins in each person, especially when it comes to children.

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

That said, not all coughs are the same and more 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, 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 are affecting, sometimes simultaneously to 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 produce a small wheezing

Parainfluenza is the name of the virus not only responsible for the inflammation of these organs already mentioned, but also the expulsion of abundant mucus, mostly in babies, and especially in climatic seasons characterized by its cold and humidity, as well as it is winter.


The croup of croup or dog, according to the specialized medical literature, 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 mostly 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.

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

Among the symptomatology generated in the patient is, apart from fever, a greater respiratory difficulty with stridor settling, with nasal flapping and narrowing of the ribs, as well as accelerated breathing.

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


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


As in any disease, the history is a very important instrument to demonstrate the mode and presentation of the disease analyzed. It is necessary to know in the case of these forms of infectious cough 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, atypical aphonia in cough, among others.

In view of the fact that 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.

If the doctor, however, feels that he needs to rule out other possible processes that may be involved in the condition being analyzed, 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, in those cases in which the disease has not been so invasive, a rather moderate treatment will be prescribed in which the humidifiers are decisive for the improvement of the disease.

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

Since in the case of them being nervous would imply a relapse and worsening of the symptoms.

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

Those cases of urgency (which are rare), the child will inexorably require artificial respiration and even dose of adrenaline to stabilize it.

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

Precisely because of the mutations that the croup could have, it is always advisable to maintain a constant and fluid communication with the child’s doctor in order to prevent major problems in time.

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

Finally, this type of 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.
