I put a few photos in the group of my little kids doing the agility thing. I can't post the really good photos because they are copywritten by the photographers. Sigh!
Agility is a great sport. My friend has run a 4 pounder (the teeter totter is designed to tip to the ground in 3 seconds when a three poind weight is at the end). The lowest jump height is 4 inches for most organizations. Also, classes such as Jumpers do not have the big contact obstacles like the A-Frame, dog walk and teeter. My male runs 8 inches ususally; my female is a 12 incher. I also run them in veterans/preferred classes to jump at a 4 inch lower height for some organizations. There is also an organization, the Teacup Dog Agility Association (www.k9tdaa.com <http://www.k9tdaa.com> ) specifically for smaller dogs. The distances are shorter between obstacles providing a challenge for the team that you don't often get at the other organizations. Be careful though, this sport is HIGHLY addictive.
