3M™ Littmann® Classic III™ Stethoscope

Build an Ear for Veterinary Heart and Lung Sounds

The 3M™ Littmann® Classic III™ Stethoscope gives veterinary learners a versatile instrument for developing one of the most fundamental physical assessment skills: auscultation. Students can practice identifying normal and abnormal heart and lung sounds while learning how patient positioning, stethoscope placement, and listening technique affect what they hear. Its dual-sided chestpiece makes it useful across a range of appropriately sized animal patients, giving learners experience adjusting their approach as patient size and anatomy change. Instructors can incorporate the stethoscope into physical exams, cardiopulmonary assessment labs, anesthesia monitoring, patient signs monitoring, and other simulation scenarios rather than limiting auscultation to a standalone exercise. Because these skills translate directly into clinical assessment, students can use the same stethoscope as they progress from classroom practice and simulation to appropriate hands-on veterinary training.
