ABSTRACT
Sensory disorders can impair a person or a dog’s ability to function normally in society. It is clear that blindness and deafness are relatively easily recognized and quantified in humans. Even in animals, diagnostic tests to evaluate vision and hearing are validated and available. Furthermore, these tests do not require a training or learning component, as they are typically based on electrical stimuli. For example, an electroretinogram captures activation of the retina and is used to confirm blindness, whereas the brain stem evoked auditory response can be used to diagnose deafness.
