There are many factors that go into choosing the right training school for you and your dog. Certainly distance is a consideration; however, convenience shouldn’t be the only factor that influences your decision. Other things like training methods, appropriate classes for your needs, compatibility of the instructor’s personality with yours, and certifications of the instructor should also play a role.
Once your dog is ready to start agility training, your best bet is to find a class or group in your area. The United States Dog Agility Association (USDAA) offers a directory for agility groups in each state, and many dog trainers offer classes as well. In the classes, you will be able to introduce your dog to the obstacles without the expense of buying or building them yourself.
Prong collars must never be turned inside out (with the prongs facing away from the dog's skin), as this may cause injury against the body and head.  Plastic tips are occasionally placed on the ends of the prongs to protect against tufts forming in the fur or, in the case of low quality manufactured collars with rough chisel cut ends, puncturing the skin. Like the slip collar, the prong collar is placed high on the dog's neck, just behind the ears, at the most sensitive point.
Dog intelligence is exhibited in many different ways, and a dog that might not be easy to train might nonetheless be quite adept at figuring out how to open kitchen cabinets or to escape from the yard. Novice dog owners need to consider a dog's trainability as well as its energy level, exercise requirements, and other factors before choosing a new pet. Very high intelligence is not necessarily a good thing in a companion dog, as smart dogs can require extensive daily mental stimulation if they are not to become bored and destructive.
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. Training for obedience competitions builds on basic obedience training.
Seesaw: This obstacle looks just like what you might see on a playground, with one plank supported in the middle, so that either side can be lowered toward the ground. The dog will start at one end and walk to the other, while the plank shifts with the dog’s weight. Some clubs require that this obstacle have grips or treads on them, as a safety measure.
Agility first appeared in England in 1978, as essentially a half time show at Crufts. The creators based the demonstration on horse jumping competitions, intending to show off the dogs’ natural speed and agility. Dog owners and trainers looking for something new to do with their pets pricked up their ears and said, “Hey, MY dog could do that.” Thus the sport was born.
