Thoracic cavity is an anatomical space enclosed dorsally by the vertebrae, ventrally by the sternum, and laterally by the ribs. It is the most common bite site in small animals, affecting on average 10 to 15% of all trauma, and accounts for 22 to 35% of all bite sites. It is associated with a higher mortality rate than bite wounds affecting other body areas. Treatment for dogs with bite wounds consists of primary stabilization, clinical examination and additional diagnostic tests that enable doctors to decide further treatment. Animals can be treated conservatively or they can be operated on if necessary. In this retrospective study, the goal was to compare patient data and diagnostic parameters to treatment outcome in 39 owner dogs. According to the processed data it was concluded that most of the admitted animals had body weight of up to 10 kg (73 %). Extent of injuries was not directly related to body weight or dog breed. It has been observed that dogs of higher body weight have higher number of broken ribs which is not correlated to the outcome of treatment.
