Details
Cone-rod dystrophy (CRD) is a type of PRA which first affects the cones in the retina, so initially results in day blindness for sufferers, and then the rods begin degenerating secondarily. Age of initial CRD (NHPH4) onset for affected dogs varied between 10 months to 3 years, with complete retinal atrophy observed by 6 years old.
Details 2
Clinical diagnosis should be made by a veterinary ophthalmologist using the methods of indirect ophthalmoscopy and/or electroretinography, although this can only observe affected dogs after symptoms have developed and will never detect the symptomless carriers. Cone-rod dystrophy (CRD) is a type of PRA which first affects the cones in the retina, so initially results in day blindness for sufferers, and then the rods begin degenerating secondarily.The NPHP4 gene was found to be shorter in all of the clinically PRA affected dogs. The age of initial CRD (NHPH4) onset for affected dogs varied between 10 months to 3 years, with complete retinal atrophy observed by 6 years old.

Application in the Breed
Carriers may be bred to normal animals (N/pra x N/N). Offspring should be tested before breeding. No breeding of two carriers (N/pra x N/pra) nor of affected animals (pra/pra). Retina cells are lost slowly : Problems seeing in dim light. Rarely complete blindness.
