What is included in the otic exam components?

The otic exam is specifically designed to assess the health and condition of the ears in canines. Within this context, examining the lateral ear canal is a fundamental part of the procedure. This component allows the practitioner to look for signs of inflammation, infection, wax buildup, or foreign bodies that may be affecting the ear canal's health. A thorough examination of the lateral ear canal is critical, as many common ear issues in dogs originate from this area.

The other components listed do not pertain to the otic exam. For instance, a skin tent is typically a measure of hydration status rather than an ear-related assessment. The color of the eyes relates to ocular health, and heart rate is a vital sign assessed during a general health examination, neither of which provides information about ear health. Thus, the correct choice focuses directly on the specific structures and conditions relevant to the otic examination.
