Big bones, strong structure, dick skin and expression of spanish presa was combined with noble, balanced character, high game, perfect catch and hunting abilities. Troll belonged to las Tinieblas kennel. We used Troll once with Calabriafor her first litter. He transmitted most characteristic typically for Carpintero line but improved by Calabria.

Her quality is visble in our female line started at litter Troll x Calabria – Vengo Araya , Vengo Flecha , Vengo Kana.
