Details
Day Blindness also known as Achromatopsia , or color blindness, is characterized by cone photoreceptor dysfunction, causing severely reduced or complete vision loss during daylight hours. Dogs may also show signs of avoiding bright light or distress in bright light (photophobia). The disease is present at birth (i.e. it is congenital) and clinical signs show when dogs are approximately 8-10 weeks of age.

Application in the Breed
Carriers may be bred to normal animals (N/achm2 x N/N) . Offspring should be tested before breeding .No breeding of two carriers (N/achm2 x N/achm2) nor of affected animals (achm2/achm2). Day-blindness in bright light, normal vision in dim light.
