• CEA,  CEA/CH,  CH,  Choroidal Hypoplasia,  Health


    CEA (Collie Eye Anomaly) is the name given to a group of eye defect afflicting many herding breeds. Currently there are DNA tests for many of herding breeds for CEA, but unfortunately our breed is not one of those breeds*. CEA is a group of eye anomalies, one of which is CH (Choroidal Hypoplasia). Actually the DNA test for CEA is actually a test for the genetic marker indicating CH. So, how can you know then if your dog is affected or not then? There are only a few ways to know. The most reliable way to know if your dogs are affected or not is for all puppies to have their…

Wahl, Christine A. Rees, and Keith E. Murphy) Intro – Merle is a pattern of coloring observed in the coat of the domestic dog and is characterized by patches of diluted pigment. This trait is inherited in an autosomal, incompletely dominant fashion. Dogs heterozygous or homozygous for the merle locus exhibit a wide range of auditory and ophthalmologic abnormalities… (NOTE: The Pyrenean Shepherd is referenced in this article.)
