AKC created new Agility titles based on a dog’s lifetime achievement agility runs. As of July 1, 2012, AKC updated its files and grandfathered in the new titles based on agility legs earned on or after January 1, 1999.
Dogs earning titles after July 1, 2012, will automatically be updated on PCA’s Online Book of Titleholders with the Lifetime Achievement title(s).
From the AKC Agility In the Zone online newsletter for June, 2012:
Now all of those ‘extra’ qualifying legs from the Excellent B classes that you often didn’t think much about as you were not ‘working on a double Q’ that day, count towards the new Lifetime Achievement Titles.
In order to recognize consistency and longevity in the Master Agility Excellent (MX), Master Excellent Jumpers With Weaves (MXJ) and Master Excellent FAST (MXF) classes, the AKC will record a Lifetime Achievement title on the dog’s record. There will be a Bronze, Silver, Gold, and Century title associated with both the regular and preferred standard, JWW, and FAST classes.
The new titles take effect on July 1, 2012. However, they will be retroactive for any legs earned on or after January 1, 1999.
