Abstract

Tracheal collapse is a pathology characterized by deformational changes in the tracheal rings and the development of a complex of changes leading to cardiopulmonary failure and severe death of the animal. The article presents the results of a study of the prevalence of tracheal collapse in dogs without a clinical manifestation of pathology. 79 clinically healthy dogs with ornamental breeds weighing up to 4 kg were examined with respect to tracheal collapse. Studies using endoscopic visualization of the condition of the trachea were performed during routine surgical operations. It was found that in dogs of ornamental breeds, subclinically occurring collapse of the trachea was revealed in 77,2%, characterized by changes in the 1st – 3rd degree of pathology. When analyzing the age-related predisposition to the disease, it was determined that the pathology is more common in dogs aged 1 to 3 years, with a 1-2 degree collapse being the most common. No sexual determinants have been identified, and Yorkshire Terrier dogs are the most susceptible in pedigree. When analyzing the relationship with orthopedic pathologies, the relationship of the tracheal collapse with the medial dislocation of the patella was established. We believe that this disease is associated with pathologies of connective tissue histogenesis, which is confirmed by the greater incidence of tracheal collapse in dogs with a dislocation of the kneecap. The data obtained make it possible to substantiate methods for the prevention and diagnosis of tracheal collapse in dogs, as well as to develop methods for clinical examination of animals at risk for the development of this pathology.
