The valve prolapse is a condition resulting from degeneration of tendinae chords and valve leaflets, which prevent the affected valve to perform its function closing properly, causing blood reflux during ventricular sistol. This reflux will lead to secondary systemic changes, such as pulmonary hypertension, pulmonary edema and congestive heart failure, if not treated properly. In auscultation, a cardiac sound is emmited when there is valve prolapse it called "murmur", which can be classified into grades from one to six. This study aims to report the case of Mike, dog, Shih Tzu, male, 3 years old, antended at Hovet Ung in 2012. As history, the main complaints were of prostration and an recent episode of syncope, and respiratory noises when excited. On physical examination the animal had a murmur, mitral valve focused, grade IV - VI, however, it was not constant. This uncommom condition is known as “Intermitent Murmur”.

Folliculitis furunculosis is a deep pyoderma affected commonly by Staphylococcus pseudointermedius. It is a disease characterized in purebred and crossbred dogs Shepherds and other herding breeds like Dalmatians and Bull Terriers. The cause of infection can’t be defined; it is believed that there is a genetic predisposition and an immunodeficiency T-lymphocyte cell that often aggravates factors linked to worsen the picture. The diagnosis is based on physical examination, history, race, age of the animal, as well as findings of cytology and histopathology. For treating the case, it is necessary the use of antimicrobials and anti-inflammatory drugs, associated with topical therapy. The study reports the changes found and the therapeutic protocol of a disorder identified in an animal breed Pit Bull, which is consistent with changes in a worldwide characterization folliculitis furunculosis in German Shepherd breed.
