Anatomy of the Canine Ear

Dogs are better able to utilize their ears’ abilities in comparison to a human. In fact, humans hear up to 20,000 hertz, while dogs can hear up to approximately 60,000 hertz. The anatomy of the canine ear is part of what enables dogs to have a wider range of hearing.

  1. Outer Ear

    • In dogs, the outer ear features the flap of the ear known as the pinna. This flap can be upright or it can be floppy, depending on the breed. The outer ear also contains the opening of the ear, known as the ear canal.

    Ear Canals

    • In dogs, the ear canals start out vertical, then turn horizontal in the inner parts of the ear. The ear canal connects the outer ear with the inner ear and is important for transmitting sounds.

    Ear Drums

    • The ear drums are between the outer ear and the middle ear. When sound is heard, the membrane of the ear drum vibrates and transmits the information to the brain.

    Middle Ear

    • In dogs, the middle part of the ear is on the opposite side of the ear drum. According to the Newman Veterinary website, it contains a large chamber full of air that aids in hearing lower-pitched sounds.

    Inner Ear

    • The inner ear is connected to the brain and, according to the Washington State University College of Veterinary Medicine, it contains the nerves and is the hub for the dog’s hearing and balance.
