What is it?
Kennel cough is a highly contagious respiratory infection that mainly affects dogs living in groups. It causes inflammation of the upper airways, leading to a characteristic cough. It usually resolves well but can worsen in puppies or weak dogs.
This disease often results from a combination of several infectious agents, including viruses and bacteria such as Bordetella bronchiseptica. The combination of multiple agents makes the infection more contagious and sometimes more severe.
Dogs living in groups, such as in boarding facilities, shelters, or shows, are particularly exposed. Puppies, elderly or immunocompromised dogs, as well as those exposed to stress or poorly ventilated environments, face increased risk.
Commonly observed signs
These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.
The main sign is a dry, harsh, persistent cough, sometimes followed by a gagging sound or vomiting. Mild nasal discharge, sneezing, and reduced energy may also occur. Fever and loss of appetite are rare but possible in more severe forms.
When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Transmission
The disease is mainly transmitted through the air, via respiratory droplets released during coughing or sneezing. Close contact between dogs, especially in kennels, boarding facilities, or shows, promotes its rapid spread.
Diagnosis and care
Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.
If your dog has a persistent cough or unusual signs, it is important to consult a veterinarian for proper advice. Only a veterinarian can assess the severity of the situation and recommend appropriate care.
Prevention
Regular vaccination against the main causative agents is the most effective preventive measure. It is also advisable to avoid contact with sick dogs and maintain good hygiene in group living environments.
