There is an excellent Mule & Donkey trainer near Ft. Worth. Her name is Janet Vance and I know of her because my Best Friend rides and shows Mammoth Donkeys. Her donkey is from her prized Jack and He is the sweetest thing on four hooves. You might look her up on FaceBook or the web and see if she can offer some advice.
I've seen her animals at shows and they are amazing! :) Posted via Mobile Device
