Una Parline comes from an excellent dam line. Her dam’s siblings include Alicante (by Casall), successfully competing at 1.60 m level, as well as Idaho M (by Eldorado vd Zeshoek) and Lucky Number One (by Numero Uno), both successfully competing at 1.50 m level. Una is sired by Dallas VDL (Douglas × Heartbreaker), who not only competed at 1.60 m level himself, but has also produced offspring beginning their careers at the same level.
