Abstract: To date, there is no known evidence of a parasitic invasion of Oslerus osleri in Bulgaria, in contrast
to its widespread use in incidence in the United States and Canada. Globalization and the free
movement of humans and animals in the world are therefore predisposing factors for the spread of
infections and invasions in different latitudes. After infection with Oslerus osleri, dogs show signs of
tracheobronchitis accompanied by permanent cough and worsening of the general condition.
The aim of the study was to determine the age groups of the infected animals, to examine the effectiveness
of three specific anthelmintic therapy schemes, and to establish a clinical protocol for testing
dogs for Oslerus osleri as part of the differential diagnosis of tracheobronchitis.
