Look up local dog clubs in your area. Ours in Missouri is Greater Kansas City Dog Training Club. They have Obedience and training for shows. Hope this helps.
I have experimented with several different types. My favourite by far is a lambs leather half choke all in one. I feel I have enough control and they can't easily escape from them either!
I think what it may mean though a little hard to say out of context is that it is a BRACE Class where non-regular class entries are not eligible to participate. Not sure though.
