Original publication title: Inner ear morphology in a bilaterally deaf Dogo Argentino pup.
Plain-English summary
A 43-day-old female Dogo Argentino puppy was found to be bilaterally deaf during a hearing evaluation. Examination of her inner ears showed significant damage, including degeneration of important structures needed for hearing. While some parts of her inner ear were normal, the findings suggest that her deafness was likely due to a genetic issue present from birth. This case highlights the potential for congenital deafness in Dogo Argentinos, similar to what has been seen in other breeds like Dalmatians.

Abstract
Two bilaterally deaf and three unilaterally deaf pups were identified from a litter of 10 Dogo Argentino pups presented for hearing evaluation by electrophysiological investigation. One pup, a bilaterally deaf female aged 43 days, was available for histopathology. Examination of both inner ears revealed bilateral cochlear degeneration with atrophy of the stria vascularis, collapse of the cochlear duct, degeneration of the organ of Corti, and abnormal tectorial membrane. The left vestibule, including the sacculus, was normal. The spiral and vestibular ganglia were essentially normal. This is the first histopathological description of lesions associated with deafness in a Dogo Argentino, but abnormalities were similar to those previously described in deaf Dalmatian pups and in other white hair-coated breeds. The defect was classified as a cochleosaccular degeneration. It was probably congenital and genetic causes were suspected.
