I will get into agility when he is a little older, his bones are still too immature for that yet. I would also like to get Khalani into becoming a "therapy" dog as he has a beautiful nature, He can't be assessed for that until he is at least 18 months old.
You must tell me more about the "skateboard", does he ride it? Have you ever videoed your agility, I'd love to see that.
There are a few youtube videos of Zest! doing agility. Just seach "Zest Agility" and the r/w little basenji is mine. Those are all from her Novice days. She's now in Excellent. We've had quite a few set backs, but she has achieved her excellent agility titles in AKC. You can see my other 2 here:
All but the dogs on the table are mine. Zest is also the star of the Agility Manuevers videos.
Hopefully, you'll be able to find a local agility class. There are lots of foundation work you can do with puppies before you start doing jumps and weaves.
The other two (Digital the brindlewonderkid and Jet the trying) are retired, but have certainly done a lot.
Therapy work is so rewarding! You'll love it. Z and I are off to the Alzheimer's facility tomorrow. Both my boys also really loved it.
