I agree that it would be a good idea to visit some classes and get your name on a waiting list if you can........I was chatting to our Agility trainer last week and she said that some classes are in such demand that there is now an entrance assessment
Fortunately, our classes are for fun and although they are in great demand, there is no pressure to have a dog that meets a certain standard........but if you find a class you are happy with and want to establish the basics, then a reasonable recall, a reliable wait and you could even practice with a childrens play tunnel and a set of homemade weaves
