Actually, both the Bedlington and West Highland white terriers are affected by
this disease.  It does have a genetic basis, however, many of the details have
slipped my mind.  Also sheep on a molybdenum deficient diet can be affected by
copper toxicosis that results in a hemolytic crisis.  I hope that helps.
