Is this the same Xochitl who was Dog of the Day last July? See http://DogoftheDay.com/archive/1999/July/03.html . Sometimes I have heard of dogs learning to play from another, often younger dog. Does Xochitl have any puppy friends who might teach her? If it is the same Xochitl, she's such a beauty that I cannot imagine anyone abusing her, but I do hope you stick with it - I bet she'll catch on and surprise you some day!
