Thanks for the info! I may have to try that. Not that I plan to ever show/breed her, but it would be cool to be able to do it on her part (so to speak). She's only got three legs (due to an injury before I adopted her) and with that, plus her hard life of being dumped and rescued, it'd be nice to "put a feather in her cap".
Most of the associations won't allow a three-legged dog to compete, but I THINK that one of the other associations allows them to compete in the Tunnelers class. Not sure which one - I've only competed in AKC and USDAA, and neither one allows dogs that are lame or have a deformity.
If you Google dog agility and disabled or handicapped, something ought to come up.
