i am thinking of taking sky to agility,but as you would be im wary.there are probably post on this already,but im feeling lazy and dont wanna look.she has all the basic commands,sit stay,lay,come here you little bugger! and very good retrieving,so, would anyone do more before they took a dog or go for it and advance the dog at classes?

Well i know that many people in my agility class didn't even have there dogs sit/stay downpat so you should be fine. Depending on the class, you start from absolute basics. But if you want to make it easier then yes it is good to have the basics. Me and my girl already new all her obstacles/contacts etc but we are doing the class incase there was anything we missed and you have to do it to get to the beginners/intermediate class.
