The ear is prominent both in its function, by giving us an insight into the how the dog is feeling both physically and emotionally by looking at their posture. Also as a reminder that demonstrates the dogs personality and character. And from the veterinary standpoint, the ears are a good place to begin a physical exam to check for both specific and general diseases.
The anatomy of the ear can be divided into four parts of the ear flap (auricle or pinna); external ear canal (external auditory meatus); middle ear; and internal (inner) ear. The dog’s ear canal is considerably longer than its human counterpart, and after extending downward, it makes a sharp turn inward toward the eardrum.
The eardrum separates the external ear from the middle ear, containing three small bones within the middle ear, the malleus, incus, and stapes. The inner ear consists of two main parts: the cochlea (end organ for hearing) and the vestibule and semicircular canals (end organ for balance).
