Early Onset Adult Deafness, EOAD

What is EOAD?

This form of Early Onset Adult Deafness is due to a variant in the EPS8L2 gene which likely causes degradation of inner ear hair cells.

What are the signs & symptoms that develop in affected dogs?

Signs of hearing loss can include no longer responding to sounds like clapping, knocking, doorbells, or the dog's name. A dog with hearing loss may also be difficult to wake.

When do signs and symptoms develop?

Affected dogs may have normal hearing after birth, but exhibit progressive hearing loss between 4 and 24 months of age.

How do vets diagnose this condition?

Hearing disorders are generally clinically examined by using brainstem auditory-evoked response (BAER) testing to confirm unilateral or bilateral deafness.

How is this condition treated?

There are no widespread treatments. Management is aimed at lifestyle changes, training, and reducing the risk of injury.

What actions should I take if my dog is affected?

  • Train using visual cues instead of sounds
  • Avoid startling the dog
  • Put tags on leashes or collars identifying the dog as deaf
