There was a dog agility show at the Sugartown Historic Days. I didn't see any dogs that would win a National contest but all the the dogs put in a good show and entertained the crowd.
Most of the dogs didn't want to go through the tunnel and more than one dog stopped and greeted a spectator at the fence. The handler said the 9 month old corgi didn't know how to weave through the poles so the dog and handler just ran past without trying.
For the jumps the bar height was adjusted based on the size of the dog. The little dachshund could easily clear the bar these big dogs jumped over. That little dog could fly.
