One correction and a couple additions for ya.
The AKC Herding Championship is just HC...people often think its a typo for a CH on Elsa's name
Also, in Canada (CKC) you can now earn additional obedience titles as follows:
OTChX (Obedience Trial Champion Excellent)
MOTCh (Master Obedience Trial Champion--only one Rottweiler has reached this level so far)
GMOTCh (Grand Master Obedience Trial Champion)
