I train all my dogs myself. I learned that from my grandpa when I was kid, and later in the military.
She is a show quality Dogo, I will show her when I have time, but to me working ability is more important than show titles. I am not a breeder (if I breed them, I breed for myself.), show titles is not what I am after.
