"Breed predisposition describes a tendency to disease based on genetic, morphological, and physiological characteristics. Long—term breeding of breeds has increased some signs and increased the risk of hereditary diseases," explained Roman Katargin, Associate Professor at St. Petersburg State Medical University.

He added that taking into account the breed predisposition is important for early diagnosis and personalization of preventive strategies.

In addition to osteosarcoma, tracheal collapse is more common in small dogs, and mastocytoma is mainly found in bulldog-like breeds. Owners are recommended to have an annual medical examination, taking into account the diseases typical for their pets.
