How do you teach a dog to jump through a hoop?

Have someone with you at first, make sure your dog knows how to sit and stay. With the one person holding the hoop, have your dog sit and stay about three feet from the hoop, go to the other side of hoop, with a treat, and call your dog(make sure you start the hoop close to the ground, if he/she tries to go around the hoop say no, if your dog is too shy to jump through the hoop you can show he/she by going through the hoop yourself. Good luck!!!
