hello Sharonda, agility is a coarse of different obstacles. you have the A-frame which is what is sounds like a frame that the dogs have to walk up and then over the top and back down the other side. then you have what is called the dog walk. it is a 6 inch beam that they have to walk over usually 5 feet tall. then you have all the jumps including a tire jump where they have to jump through the tire that is held by a frame. you have a shoot that starts out as a barrel then turns into fabric which they have to make there way through. (Buckley has trouble with this one because he got stuck and twisted in it once). then you have the tunnels which they have to go through. they are turned and curved so they cant see through it to the other side. some are light and some are dark. I think I got all of them.... but may have missed some. this is all done in what they call a ring. the dogs cant go potty in the ring or in a competition will be disqualified. there are different levels in agility. we are intermediates right now. haven't done much in the way of competitions with Buckley but maybe in the future. right now we just go to have fun. hope this has helped some.
