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.

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.
Some Norwich Terriers suffer from an upper respiratory obstructive syndrome that differs from brachycephalic obstructive airway syndrome.In a study of 12 dogs with signs of the condition 11 had abnormalities of the laryngeal opening with redundant aryepiglottic folds, laryngeal collapse, everted laryngeal saccules, and a narrowed laryngeal opening all being observed in multiple dogs.
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]
