Plain-English summary
Three working dogs developed hearing loss after being exposed to loud noises. Despite thorough examinations, the dogs showed no other health issues, but tests confirmed they had bilateral sensorineural deafness. One dog couldn't regain hearing but adapted to using hand signals at work. Another dog was lost to follow-up, while the third dog was treated with a daily regimen of Vitamin B complex, Vitamin E, and N-acetyl-cystine. After two months, this dog regained its hearing, as confirmed by follow-up testing.

Abstract
Three working dogs were diagnosed with noise-induced hearing loss following exposure to loud noise. Physical and neurologic examinations in each case revealed no significant findings. Brainstem auditory evoked response (BAER) demonstrated bilateral sensorineural deafness. One dog did not regain hearing but continued working with adjusted protocols utilizing hand signals. One dog was lost to follow-up. The last dog was treated with oral Vitamin B complex (daily), Vitamin E (400 IU daily), and N-acetyl-cystine (600 mg daily) and regained hearing 2 months later, based on repeat BAER testing.
