It's more commonly referred to as Legg Perthes disease. It's considered a genetic disease. The hip joint disintegrates due to lack of blood supply. Surgery is usually the only option to prevent the dog from going lame or suffering pain.
You need to contact your breeder and personally I would take him to an orthopedic specialist.
