The primary objective of the experiment was the evaluation of endoscopic examination usefulness for the diagnosis of respiratory tract diseases in dogs. The experiment was conducted on 77 dogs of various breeds, sexes, sizes and ages (7 months - 14-years-old). Group no. 1 was selected from some healthy dogs, and group no. 2 was consisted of dogs with respiration problems. During the experiment endoscopy examinations of lower and upper airways were conducted in dogs classified for the experiment. In substantiated cases, microbiologic swabs and tissue samples were taken during bronchoscopy for additional tests. The results of bronchoscopy exploration in dogs evidenced its special usefulness for the diagnosis of inflammatory and deformation processes in the respiratory tract. In cases of aspiration of some foreign bodies that could not be detected on the Rtg, only fiberoscopic examination was the appropriate diagnostic tool. Microbiologic and histopatologic examination of the obtained samples was very useful in the diagnosis and treatment of respiratory tract diseases in dogs.
