What common disorder in dogs could potentially lead to hearing loss?

The choice of deafness as a common disorder in dogs that could potentially lead to hearing loss is accurate because deafness itself directly pertains to the loss of hearing. In dogs, there are various causes of deafness, including congenital factors, age-related degeneration, exposure to excessive noise, and certain infections or medical conditions that affect the auditory system.

Understanding that deafness can manifest in different forms—such as congenital deafness known to occur in specific breeds—highlights its relevance as a disorder associated with hearing loss. The link is clear: deafness is the condition characterized by a deficiency in hearing ability, making it the most straightforward answer to the question presented.

In contrast, hip dysplasia is primarily a skeletal issue that affects the hip joints, while cataracts are an eye condition impacting vision, and "frog face" is not a recognized medical condition in dogs. Consequently, these options do not directly relate to the possibility of hearing loss.
