> If you can't find a local Ringcraft Class, I'd not rule out doing the same - going to an Obedience class and getting them to allow you to stack etc
My Obedience class lets me do that, I know the organiser well, in fact she used to show a bitch I had back at 7 months and she gave her a home.
I don't have them sit during heelwork but have them stand, and do stands instead of sit stays, and use steady for looser heelwork appropriate to moving a pup at show speed.
Down stays are useful, as are recalls, for whatever discipline.
Did quite well at Obedience often running off against her collie kennel mate at the local Exemption shows top class.
