A highly contagious acute respiratory disease spread by close contact causing larngitis, *[[Trachea Inflammatory - Pathology#Infectious causes of tracheitis|tracheitis]], [[Bronchi and Bronchioles Inflammatory - Pathology#Infectious causes of bronchitis or bronchiolitis|bronchitis]] and in some cases a [[Nasal Cavity Inflammatory - Pathology#Rhinitis|rhinitis]].

Multiple agents are implicated in the disease including [[Canine Adenovirus 1|Canine ''Adenovirus'' 1 ]],[[Canine Adenovirus 2|Canine ''Adenovirus'' 2]],[[Canine Herpesvirus 1|Canine ''herpes'' virus]],[[Canine Parainfluenza - 2|Canine Parainfluenza - 2]],[[Canine Distemper Virus|Canine Distemper Virus]], [[Category:Mycoplasmas|Mycoplasma species]] and [[Bordetella bronchiseptica|''Bordetella bronchoseptica'']]. Very common disease in dogs that are housed in groups.

''B.bronchoseptica'' adheres to ciliated epithelial cells in the trachea where it proliferates and releases toxins causing epithelial necrosis and prevents ciliary clearance.Irritation to tract causes coughing. Mortality rates are very low it is a commo disease in dogs that are housed in groups.
