Details
gPRA in Schapendoes is characterized by late onset and slow progression. Affected Schapendoes dogs appear normal when young, but develop gPRA between 2-5 years. Early in the disease, affected dogs are night-blind, progressing to full blindness within 2 years.
Details 2
gPRA is transmitted in an AR manner. gPRA in Schapendoes is characterized by late onset and slow progression. Affected Schapendoes dogs appear normal when young, but develop gPRA at an age of onset between 2-5 years. Early in the disease, affected dogs are night-blind, lacking the ability to adjust their vision to dim light; later, their daytime vision also fails. This process of complete photoreceptor degeneration takes up to 2 years. (Lippmann et al, 2007)

Application in the Breed
Carriers may be bred to normal animals (N/gpra x N/N) . Offspring should be tested before breeding . No breeding of two carriers (N/gpra x N/gpra) nor of affected animals (gpra/gpra). Problems seeing in dim light (2-5 years of age)- within 2 years full blindness
