i like to teach mine in the comfort of there own home as well as ring classes it helps alot
i put them on there show lead and walk them around the back garden like tey would in the ring
then put them on the table and go over them and i get friends and family to as well so they et used to different people approaching them and going over them
i find what else is good is involving them with like going to the shops and stuff so lots of different people see them and come over for a stroke thats helping with ruby as she is shy in every aspect but learning fast
