There are many organizations that offer agility titles for dogs.
Even so, many people train their dogs in agility just for the enjoyment
of developing teamwork with their dogs and the sheer fun of agility.
Some obstacles your dog learns to navigate include the A-Frame,
Teeter-totter, Open Tunnel, Collapsed Tunnel, Tire, Weave Poles,
Pause Table, Crossover, Dog Walk and various types of Jumps. Obstacles
like the A-Frame and Teeter-totter have "contact zones"
at the beginning and the end where the dog is required to touch
at least one paw (on the up, down or both depending on the organization)
while on that obstacle.
