Deafness in an old English sheepdog. A case report.
The histopathological features of the inner ears in a case of deafness in an old English sheepdog reveal a cochleo-saccular (Scheibe) type of degeneration. However, also the hair cells in the vestibular part of the labyrinth were reduced in number though there appeared no clinical signs or symptoms of vestibular dysfunction. The present case is the so far only known old English sheepdog with a hearing loss reported in Sweden.
