not sure where you are in. I would imagine Lansing would have a training club. I took Dora up there for her Rally Excellent title. They were very nice, had great food, etc. Some of the actual obedience clubs require obedience classes/testing before you can go on and do agility. I would say check AKC and even if they don't do agility. You can ask them for places or private lessons. The midwest is very known for "clubs" which are great!
In Columbus, Dora was required to complete 4 obedience classes before she could test into agility but now she loves it! This weekend they have the agility nationals here in Columbus. I am going to watch on Saturday-very excited. A few of my friends are competing and my training club is sponsoring and working a ring.
