Thank you Savvylover and Katana for your suggestions.
I will look into the Savvy club and I already found some used DVD on e-bay, most sellers don`t ship here but I will have a friend in the US re-send them to me, so that is almost done. Which serie do you think I should get: Playing the 7 games or Level 1 ? (can`t afford both at this time!).
Katana, I don`t know of anybody here who would own a Parelli DVD, I don`t even think they have been translated to Spanish.. have they? And Parelli is not well known around here, although many people does natural horsemanship.
Thank you again for your help.
