Shasta passed it at 3 years old. Actually just this past June. She's a German Showline cross. I probably could have tested her earlier but I didn't have a whole lot of faith in her ability to pass anything relating to dogs because she gets excited and pulls.
Dax... he's got a ways to go before I'll even consider TRYING to test him. He's Czech/ddr. He's a bonehead. I'll hopefully get him close to where I'll test him on it when he's about a year old but we'll see. I have a lot of "chill out" work to do with him.
The more people I meet and talk to,the more I love my dogs and their intelligence.
