For every recognized breed of purebred rabbit (Kelinci Holland Lop) there is a written standard which describes, in detail, exactly what the breed should look like.  It describes all of the breed’s physical features and exactly how they are to look and fit together.  The purpose for the written standard is so everyone raising that breed will be working towards raising the same typed rabbit for that breed.  A recognized breed of rabbit (kelinci) has gone through a lengthy process which takes 3 years to complete.  Each of the 3 years must show an improvement in conformation, using its temporary written standard.  At the end of the 3 years, if all has gone well, then the breed becomes recognized and its’ standard is then placed in a Standard of Perfection  ARBA (SOP).
