Great list!

The most comprehensive list of dog sports titles I found (note that tracking titles are listed under obedience titles):
http://www.caninetrainingsystems.com/resources/dog-sport-titles

Thanks for adding that! Certainly easier than me trying to list them all here.

No freestyle titles listed, though.

This list has many of the German rating terms translated/explained. Some spelling is incorrect but the meaning holds.

PS I would add
'DSH' = Deutscher Schäferhund
analog
'GSD' = German shepherd dog (which is in the list)

ha ha one of the guys in our training groups license palte reads DSH SCHH ha! now i know what it means.
