Gee, No I haven't thought of TDAA. I have been working on getting their VCD titles. Becky has her CDX, MXJ, AX, RA, and I am hoping this fall to get her TD. If I can, she will be only the 3rd. Eskie in the history of the breed to have an AKC Tracking Dog title. I would love to get an OTCH on her, she should have her MACH this fall, but running a business doesn't leave a lot of time for training.
