==History and Clinical Signs==

Often a history of exposure to other dogs at either rehoming centers, bording kennels, in a hospital etc. Direct contact or aerosol spread are the most common routes of infection.  

Often a history of exposure to other dogs at either rehoming centers, bording kennels, or in a hospital etc. Direct contact or aerosol spread are the most common routes of infection.  

Clinical signs develop 3-5 days after exposure. Signs are often mild and self limiting.  Afected dogs usually have a dry hacking cough which is likely to be exacerbated on exercise or excitement. Sometimes serous nasal discharge, fever and lymphadenopathy are present.

The clinical signs typically persist for 2-3 days to 2-3 weeks.

The clinical signs typically persist for 2-3 days to 2-3 weeks.

Systemic signsare likely to indicate the development of bronchopneumonia, signs include pyrexia, inappetance and depression. Systemic disease is more likely to occur in young or immunocompromised animals. This condition is usually a result of secondary infection with pasturella and streptococci bacteria.

Diagnosis is most often made on clinical signs and physical exam ruling out other causes of the cough.

==Radiography==

==Radiography==

Thoracic radiography and ultrasound are often unremarkable.

Thoracic radiography and ultrasound are often unremarkable however may help to rule out other causes of the cough.

==Endoscopy==

==Endoscopy==

Tracheal cytology may reveal inreased numbers or neutrophils and bacteria.  

Only considered when kennel cough is amongst a large numbe of differentials. It will allow to collect tracheal samples allowing for tracheal cytology which may reveal inreased numbers of neutrophils and bacteria.
