Herding breeds like border collies are the masters of this game, which is why you’ll see a ton of them at trials, but they’re not the only players. Chihuahuas, pit bulls, huskies, hounds, even Great Danes. You name it, my dogs and I have probably been shown up by it at some point. Surprisingly, certain toy breeds like Papillons have a real knack for agility.
You can start training your dog before they're of age to compete. Begin by working on basic obedience and teach your puppy to sit, lie down, come, heel, and stay. Your puppy will also benefit from attending training classes where they will learn basic obedience and get used to working around lots of other dogs and people. Having your pet take and pass the AKC Good Citizen Test is a helpful step.
In competition, merely sitting, lying down, or walking on a leash are insufficient. The dog and handler must perform the activities off leash and in a highly stylized and carefully defined manner. For example, on a recall, the dog must come directly to the handler, without sniffing or veering to one side, and must sit straight in front of the handler, not at an angle or off to one side or the other.

Therefore, house training (also called housebreaking or potty training) is one of the first things you need to work on with your dog. Crate training can be a very helpful part of the training process. This includes house training as well as many other areas of training:
