Description: Progressive retinal atrophy is an inherited disease that occurs in many dog breeds and manifests itself in various forms. The form of a progressive rod and cone degeneration is photoreceptor degeneration and occurs at different dog ages. The genetic disorder causes the degeneration of retinal cells in the eye. The rods are first affected; therefore, night blindness occurs first.

However, the time of onset may vary and depends on the breed of the dog from 2 to 12 years.
