Diagnóstico presuntivo de osteopatia hipertrófica em cão da raça Shih Tzu

Pulmonary hypertrophic osteopathy (PHO) is a rare condition in dogs, especially in small breeds. This study presents a case report of a 13-year-old Shih Tzu diagnosed with PHO secondary to suspected pulmonary disease. According to the literature, PHO is more commonly observed in large and giant breed dogs and is usually associated with thoracic neoplasms, which makes this case unusual and noteworthy. The presumptive diagnosis was primarily based on radiographic findings and the presence of pulmonary changes, even without histopathological confirmation. This case highlights the importance of considering PHO in dogs of any size when persistent locomotor signs are present, particularly if associated with potential thoracic lesions.
