Inbreeding due to the small foundation stock numbers has led to Entlebuchers suffering from congenital defects, the most common of which is hip dysplasia.[1] Hemolytic anemia also is known to occur. Progressive Retinal Atrophy (PRA) is also present in the breed. The National Entlebucher Mountain Dog Association (NEMDA), in collaboration with other organizations, is working to eliminate these issues from the breed through responsible breeding, genetic testing, and fact dissemination.[2]
