How to get your dog started in agility?

Well, your first step is to lay a solid foundation in obedience training. Actual agility training won't begin until the dog is grown or nearly so (as it's stressful to their joints). When the dog is ready to begin agility training, it's best to take some classes if this isn't something you've done before. The best place to do that is through a local agility club. Your vet and/or the local shelter are likely to know of organizations in your area.
