You can also go to agility trials in your area and talk to the handlers to see which training classes they recommend.

Here is also a very interesting messageboard for agility lovers. It's packed with great information about how to get started: http://www.i-love-dogs.com/forums/dog-sports-agility/

Agility is a great way to get fit with your pet while having fun at the same time. The best way to get started is to learn more about the sport at http://www.usdaa.com/. Then, google-search for agility training courses in your area. I found three different places that offered agility in Phoenix. I chose the one that was closest to where I live. I hope this helps!

I would also like to do this with my 2 year old shih tzu who is about 2 pounds overweight. Have you heard back how to get started yet?

How did you get started? I really want to do this with my Vizslas, but I don't know where to start.

I participate in agility with my cavalier king charels spaniel and we love it. He has lost weight because of it and his tail is always wagging and he is always ready to run! I suggest getting a course put in your backyard. Then if you want to compete that is great too! We have never competed before but i'm considering it becuase it is SO much fun! Good Luck! :)

I signed my Japanese Chin, Loki, up for an Agility course last Spring. He was a natural! Some things you want to take into consideration are the dogs age: they should be full grown and comfortable around other dogs in a training environment.
