Signs and symptoms
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.
Affected dogs may have normal hearing after birth, but exhibit progressive hearing loss between 4 and 24 months of age.Uncover health risks with Embark
