The laryngeal saccules are extensions of the laryngeal ventricles as part of the lateral wall of the larynx. [1] They ascend posterior to the thyroid cartilage. [1] They are surrounded by loose areolar connective tissue. [1] This may contain lymphoid tissue, which is healthy in children and may be a sign of illness in adults. [1]

Brachycephalic obstructive airway syndrome (BOAS), also known as brachycephalic airway obstructive syndrome (BAOS), brachycephalic airway syndrome (BAS), and brachycephalic syndrome (BS), [1] is a pathological condition affecting short nosed dogs and cats which can lead ...
Packer RM and Tivers M found that the results of this surgery showed that about 25% of dogs were “breathing normally” after the procedure and about 53.6% saw much improvement. [9] Laryngeal saccule resection: when there is a grade I laryngeal collapse, the laryngeal saccules are everted. This causes another obstruction that blocks the airway.
Brachycephalic airway obstructive syndrome is a condition of brachycephalic (short-nosed) dogs, characterized by the presence of stenotic nares, elongated soft palate, narrow trachea, collapsed larynx, and everted laryngeal saccules. Signs include difficult and noisy breathing. Surgical options are available. [192]

Usually these dogs are born with a normal larynx, but over time the nerves and muscles that control the laryngeal cartilages lose function. [2] Laryngeal paralysis may also be congenital in some breeds (e.g. Bouvier des Flandres, Dalmatians, Siberian huskies, and bulldogs), appearing in dogs between two and six months of age.

Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]
