Progressive Retinal Atrophy (PRA) is a family of eye diseases that involves the gradual deterioration of the retina.
Early in the disease, affected dogs become night-blind, with the loss of sight during the day occurring as the disease progresses.
Unfortunately, there is no treatment, but it is known that the condition doesn’t cause any pain or discomfort and most dogs will adapt well to their limited or lost vision, so long as their surroundings and environment stay the same.
